That's very true and correct :)

Form my experience, here are some things that make GPU usage non-uniform / uneven in dual SLI enabled setups in particular, so in order of likelihood for pCARS:

1. Overheating of top card causing throttling of GPU speed/voltage, usually from transference of temp from bottom card (8°C to 12°C above the bottom card which is normal behaviour when 'on air cooling' as heat rises naturally) - can cause SLI to disengage in flight.
2. Breach of GPU's theoretical TDP causing the Graphics card to panic and induce throttling of GPU speed/voltage, this only needs to happen for a fraction of a second before fail-safe is brought in and can cause SLI to disengage in flight.
3. No SLI profile in drivers (there has been for a few months now, so unless you are on really old drivers or 'dirty install of drivers, should not be an issue) - SLI will not be engaged at all.
4. No in-game support for multiple GPU (usually responsibility lies between game devs and graphics driver elements) - SLI will not be engaged at all.

vSync and frame limiters can cause low GPU usage (as they should), but this will show as a uniform drop across both cards normally, unless one of the above is in play.

For example, in the case of @jrp's screenshot, it looks to me like the max TDP may have been breached and GPU2 has gone in to fail safe mode as the GPU2 speed has removed the OC and gone to stock and Voltage has dropped to stock too. In reality, when cooling is not the problem, this is the #1 cause for poor performance on SLI and is misunderstood greatly. TDP is not how hot the GPU is, but how much power (volts x amps) it can take in theory and how much cooling would need to be applied to keep it there. It's a limit written in to the firmware to protect the GPU's circuitry by the designers. It can of course be overwritten with a custom BIOS which can increase the TDP and therefore the GPU will not throttle so early.

Hope this helps.
Thanks MrPix, I'll bet it's #2 causing the issue for me. Now I need to find a fix...I'll start with the Nvidia driver, I thought Nvidia pushed an update last week right around the time my problems FPS problems began. Any advice appreciated.

Any advice appreciated.You could be on to something. The TDP limit is in firmware (BIOS)... how it is used for throttling is in the driver (what to do) and the firmware (when to do it).

Most likely though, its the rise in ambient temps outside that are having an effect ;) (My science teacher blamed every failed experiment on the weather and looking back over 50 years, he may have been on to something too)

No sorry, I don't work for SMS. I'm just a bod like you trying to help explain things.

As long as you are not using any form of vSync in game or outside of it, and you are giving the GPUs something to work on, they should be flying at 85-99% all the time... providing they are not being throttled.

Before I started to log all my GPU stats and usage, back in the day when I had SLI, I thought it was the game to blame all the while... whatever the game was... all the older games never had the issues... just the new ones!

Once I started to analyse the logs, I found tiny instances where the Thermal trip had been switched (prior to going sub aqua) or the TDP had been breached thus causing throttling. If the 'blip' is big enough it can affect both cards.... but if you are on air then the top card usually gets blipped first as it is already a lot hotter so the TDP limit is a lot closer to breach.. under water however, it's usually both cards that get throttled. If the thermal trip is intact then the throttling may sometimes be very temporary, but the throttling remains on in most cases. Of course, if you alt tab out and back in again, then the GPUs switch to 2D mode and back to 3D mode and the trip is reset, and performance climbs until it is tripped again.

Project Cars is a very demanding game indeed and can cause the GPUs to work very hard when coming round a corner to be met with the stadium and the pit lane and the pit wall and with crowds and and and... and all of a sudden the demand to render the objects rockets... this can be the moment when the TDP is tripped.

I know it sounds like I am obsessed with TDP, but since the 580's I had in SLI, it has always been the issue. Once I have added a custom BIOS (I have been under water since I got 2 580's and the top card kept hitting the thermal trip) and upped the TDP out of the way as I know I won't hit any thermal barriers in practice (I'm under water), so why should I have them imposed on me in theory (firmware).. The cards remain at the clocks and voltages I put them at when under load.

Don't forget, TDP is not what the card is actually doing in practice, it's a theoretical limit: Temp & Power Draw (voltage/current) and theoretical cooling in a equation. When overclocking, the voltage usually is increased and also the current used will be too so it will be a greater multiplier against the theoretical cooling temperature thus hitting the TDP limit faster. If the TDP limit is upped, then most likely will not be reached so easily.

Thanks for the reply, but my cards are not hitting TDP, i've both cards flashed with custom bios and under water never reaching 50 Dec C.
So I know that this is not the issue, its a software problem as alt/tab corrects it most of the time.

Are both your cards running at the same performance? I have one running at 95% and the other at 25%; that's what started the TDP talk. Reason I ask is because I'd rather not mess with BIOs if I can avoid it. Thanks

Edit: Never mind, I see in an earlier post that you state that the cards should be running the same, so I assume yours are.

Yes Cuba, both are the same % of usage, start off 90-99% then for no reason drop to 40-50% usage with half the required FPS.
Is anyone else running a 4K Gsync monitor?
Wonder if that's got anything to do with it?

I got more FPS with one GTX 980 than two GTX 980. More smooth gameplay too.

But I think there's not pCars fault. It's a SLI fault. There's not only a single racing game that I can see any benefits with SLI. All of them (and I have basicly all racing simulators) run better with a single GPU card.

SLI was an amazing marketing play of nVidia, but the results in real life are pathetic.

Is that with triple monitors though? I find running at 6110 x 1080 I need the extra SLI horsepower to keep a good framerate. With just a single monitor (unless its 4k) it probably wouldn't make much of a difference.

It might be worth adding the exact conditions (track, car, number of cars etc etc) when you are seeing low GPU usage as I've just experienced the following:

Mercedes 190/Hockenheim/Time Trial/Clear Weather - 95% usage on both GPU's the whole time (constant 60FPS Vsync)

BUT

Any car/Le Man's/Race Weekend/Thunderstorms/20 opponents - 50-60% fluctuating usage on both GPU's (frame drops to 40FPS when near any opponent cars)

I run 2 x MSI 970 G4 GTX in SLI with an overclocked I7 4770k. SLI runs smooth as silk for me and I definitely get higher framerates.

Again, I haven't read through the whole post, but I have finally gotten my SLI setup to get fully utilized (91-95%). I have locked my frame rate to Adaptive V-Sync and I stay at a constant 60fps and the game play is VERY smoth. It does drop some in some points on Brands Hatch, but I attribute that to the track optimizations that yet need to be worked on. However, in the rain... FPS takes a major hit... BUT.. My video cards are only working at about 40-50% in the rain, so obviously there is going to be a FPS hit. Is anyone else noticing that in the rain BOTH video card usage and FPS drops? So it seems that the rain isn't really taxing the video cards, it seems that is it just not utilizing them.

Correct me if I'm wrong but technically isn't an *80 GPU better than a *70? So apart from newer architecture I don't think it'll be a massive improvement.

Unless the 970 has more VRAM than your current 780, if so that might help.

Only reason I'm thinking about for 1080p is the fact my SLI 780ti SC dip to 40fps with 20+cars and rain, whether that's down to the low SLI usage or the 3GB VRAM I don't know but either way a single 780ti or Titan X should solve that, plus who knows when I might decide to get a 4k display.

Jeremy Clarkson is right on target.

I had upgraded to a 980Ti SLI set up only to crash into the same performance wall. My SLI setup works wonders on any other game in 4K without a flaw. GTAV being one of them.

My settings are: 4K, All settings at maximum possible with AA OFF and SMAA OFF. (i5 4670K at stable 4.6Ghz, 16GB RAM, Dual GTX 980Ti SC, SSD and 1200w PSU).

When I disable SLI, the single GPU usage goes up but does not achieve maximum usage below 60FPS. If I disable Vsync, nothing changes.

Below I have attached 4 images which show the following:

1. Single GPU with 30 opponent cars in view.
2. Single GPU with no cars in view (Notice the usage increase with the cars out of the picture. Shouldn't it be the other way around?).
3. 2-Way SLI GPUs with 30 opponent cars in view.
4. 2-Way SLI GPUs with 30 opponent cars in view (Same note as item # 2).

PC SPECS: i5 4670k @ 4.6GHz (NB @ 4.4 GHz) Water-Cooled | 2-Way SLI EVGA 980Ti @ 1291MHz | 16GB Corsair @ 1866Mhz | ASUS Maximus VI Hero | Win 8.1, 64bit | 512 SSD Corsair Neutron | Corsair 1200AX |

Jeremy Clarkson is right on target.

I had upgraded to a 980Ti SLI set up only to crash into the same performance wall. My SLI setup works wonders on any other game in 4K without a flaw. GTAV being one of them.

My settings are: 4K, All settings at maximum possible with AA OFF and SMAA OFF. (i5 4670K at stable 4.6Ghz, 16GB RAM, Dual GTX 980Ti SC, SSD and 1200w PSU).

When I disable SLI, the single GPU usage goes up but does not achieve maximum usage below 60FPS. If I disable Vsync, nothing changes.

Below I have attached 4 images which show the following (Just noticed the images look like crap. I will update soon)...

1. Single GPU with 30 opponent cars in view.
2. Single GPU with no cars in view (Notice the usage increase with the cars out of the picture. Shouldn't it be the other way around?).
3. 2-Way SLI GPUs with 30 opponent cars in view.
4. 2-Way SLI GPUs with 30 opponent cars in view (Same note as item # 2).

No matter what I do... I can't read the red writing on those images man... spell it out please... this forum seem to resize the pictures... OR you have downsized them before uploading... whichever.. the red writing is illegible.

I just added anotther HD6990 to my setup and I get utilization of 42-50% per core on all 4 GPUs. With just one card (2 GPUs) load is ~97% per core. So, no FPS boost, which makes sense as 4 x 4x%close to 2 x 9x% - the only benefit is that quadfire is much smoother.

Well, we know that AMD has driver issues with pCars and my cards are old, so I have very low expectations. However, here's what bothers me.

Sometimes, I do not know what happens, but I launch game and load is ~65% per GPU. That gives huge FPS boost. Same settings everywhere, I change nothing, but load is, sometimes, higher. There's something strange going on with load balancing here. I tried various settings etc, no luck, I noticed no pattern so far. It is not heat issue, not CPU bottleneck. Another interesting thing; lowering settings reduces GPU load. Also, GPU load drops in rain - just as others reported.

To your note on point 2 and 4.... with more cars, more physics are required to be calculated, so the load is heavier on the CPU... which as you can see, the CPU usage stays the same (which as an average of ~77% is practically flat out despite not being 99% on each core, the system appears to have other components that limit the CPU going above ~77% average so it seems (this is quite common), but the GPU usage goes up as the CPU calculations are less so are provided at a greater rate, so the consequence is that you see greater GPU usage because the frames can be drawn faster.

Don't know why SLI is broken for some of you. Works perfectly for me with the latest NVIDIA drivers 350.12

I made a video earlier today and you can clearly see both cards are getting above 90% utalized.

This is insane. I can't even run greater than 40FPS with two 980 Ti cards. I'm going to go back to those specific drivers to see if it improves my GPU usage for now. Unfortunately it if does, it will destroy my stability in GTA V and NVIDIA needs to get these driver under control.

Thanks for the advice, MrPix. I have added my specs. However, I don't believe my system is being bottlenecked. I will be downgrading drivers to 350.12 as there seem to be some gpu usage improvements and will report back.

Great setup but just as an experiment, pull a card and try again. SLI/xfire isn't as great as i'd thought it was going to be. I was horrified when my last card died in sli and i only dropped a couple of FPS. 20% perf boost and no shared memory is a bad marketing ploy. I know this is a cynical post but nVidia and AMD should market cards with a slave system and less money. I have an AMD 1090T and an 1 old gtx 460 and apart from raindrops on the camera i'm averaging 30+ fps. Might not be awesome at the moment but it does show what an old cpu and an ancient gpu are capable of. Most of the visual settings give negligible results at ultra or high, so it's worth experimenting.

Unfortunately, I was unable to downgrade the drivers since the only driver that works with the GTX 980 Ti at the moment is 353.06. Anything else is incompatible. However, I have been participating on a lot of forums and there is an excessive number of people running excellent FPS (Above 60FPS in the rain with 15+ cars, roughly the same graphical settings) with the GTX 780 and 780Ti and 4670K and 4690K processors. Also most of these users are running less than 16GB of RAM. The idea that these might be bottleneck issues seems less and less the more I research around forums and discuss the problem with the peers. There's no way two GTX 980 Tis can truthfully perform with less than 40FPS in the same conditions.

This person is running just one GTX 980 Ti and a "stronger", lower clocked 4790K (4.0GHz) and look at his performance:

I'm still trying to figure out whether it's the game or the drivers but this game is definitely underperforming on the GTX 980Ti. I have two of them and I cannot get them to operate at a minimum of 60FPS during rain and 25 cars. the GPU usage stays below 50% without maxing out the CPU cores. GTAV nearly maxes out my CPU but both cards run at 100% usage when they need to maintain 60FPS and the settings are as max as they can go in 4K resolution.

Take a look at this thread if you're also using SLI:

I check my GPU drivers daily, my BIOS and rest of the system like the chipset and peripheral firmware weekly. Especially if I'm going to run high over clocks. Yes, I've been doing this for the past 10 years or so. Same with the software. In the case of the GPU, there is only one driver compatible with the GTX 980Ti at the moment, if you're wondering.

It's not the bridge. Look at the 3dmark scores. Every other game like Witcher, GTAV, Crysis and Metro run flawlessly on SLI and removing a card definitely makes a difference. I deleted the graphicsconfig.xml when I installed the new cards and verified the integrity of the files through steam. In regards to EVGA precision, I used it for a long time until it started displaying the wrong FPS. The software is primitive. No need for Precision X when I can use MSI afterburner. It's not the PC.

You can rule out the CPU being a bottleneck with SLI by adding the launch options "-skipcrowds -dx11mt". Compare the GPU utilization before and after using these options!

Assuming you are using the digital Steam version:

-skipcrowds reduces small draw calls for the animated / track-side characters and grand-stand crowds.
-dx11mt enables more render threading to improve CPU performance : this will help your highly over-clocked 4670k @ 4.6 ghz if you are actually CPU bound.

Pardon my ignorance on computer science and I really appreciate your help but if this command (-skipcrowds) is going to remove or reduce the amount of crowds on the stands, I don't really want to do so. If this were my goal, I would lower the settings which still doesn't make a difference when I do in this particular game as the graphics cards continue to be underused. In addition, I'm still not clear about how -dx11mt affects the game. I don't want to apply temporary fixes which hurt the overall game graphics just to fix a performance issue that's not on my part. In advance, I promise you I'm not trying to be rude. I'm frustrated with the situation, not with anyone here.

UPDATE: I tried -dx11mt and my GPUs still performed at 45 to 55% and my frames remained between 30 and 40FPS. So does my GPU usage (40 to 50%).

Thanks for sharing this hint. I tried it on my setup (2xHD6990) and all 4 GPUs stayed utilized below 50%. So, something else is limiting full utilization in my case.
BTW: excellent scaling with just 2 GPUs in my case.

Edit: "Below 50%" applies to Hockenheim, Nurburgring, Brno. Just had race at Spa: up to 65% and great FPS (and heat :D) So, that also varies track to track. All tracks had clear weather, 23 opponents.

In this video, the user has a GTX 980 with a 4670K compared to my dual 980 Ti and the same processor. At minute 8:47 he has loaded rainy conditions with 51 opponents and he is getting the same framerate (35ish) I get with 25 opponents in the same conditions. Needless to say, upping my opponents near 50 yields FPS in the 20s. I'm not even going to mention the settings because whether it is in 1080P and or 4K I get the same results. ultra or not ultra.

Sir, just wondering, do 4 GPUs configuration need additional work in game to scale better, or same (potential) scaling improvements will apply to both 2, 3 and 4 GPU systems? Does scaling even depend on game code? Maybe load is controlled purely by driver?

I get perfect utilization for 2 GPUs, but not for 4. What's interesting is that lowering details in game lowers utilization, without improving FPS much, just as others reported.

Here, you can see my results with SLI ON and OFF with my settings at 4K, Ultra/Max possible, AA OFF and SMAA OFF.

In addition, I've lowered my resolution to 1080 in order to provide smaller screenshots below. With this said I have tested different scenarios:

NOTE: GPU usage is the percentage to the immediate right of the temperature.

SLI Disabled: 1080, All Settings Ultra/Max possible, AA OFF, SMAA OFF (No command lines used)

Whatever is causing this poor GPU usage is not my CPU. I have found countless discussions and videos on YouTube with my same processor at above, lower and same core clocks and not a single bottleneck is taking place. Jeremy's CPU is also stronger than mine as an i7 and he is experiencing the same issue. Like I said before, I have thrown the heaviest of games at my PC just for testing and every game has run flawlessly in 4K, ultra settings and never dropped below 50FPS while maintaining a high GPU usage when the game deemed necessary.

My image looks absolutely perfect (image quality, not fluid in terms of FPS) at 4K with FXAA on HIGH, SMAA OFF and AA OFF. If I enable any of those, the edges don't look as realistic. On top of that, theoretically speaking this is going to decrease my FPS which I don't want. 4K + AA + SMAA is not necessary for my monitor as it achieves maximum image quality with 4K FXAA on HIGH, SMAA OFF and AA OFF. Therefore, there should be no need for me to increase my settings just so that my cards can "work better" and lose valuable FPS down the road.

Works better than on 3xFHD screens. IQ, smoothness, zero tearing - pure beauty. Thanks SMS for for 12K ready engine, at 6K already blow my eyes ;)

We are aware that SLI works wonderfully for a lot of people. Hence all my videos throughout the thread. Thank you for the info.

Another one: 4790K processor with SLI Titan X. 4K, all ultra, particle level OFF. Only 13 opponents. Not accounting for the drop in FPS through FRAPS recording, this guy should be flying in the 60s instead of mid 30s and his GPUs only reached 47% usage.

He's running with VSync - so it's quite possible that the frame-rate is in the 50s if he were running without Vsync... As you soon as you enable Vsync in a scenario like this the GPU will idle waiting for the sync and you will get vastly reduced GPU usage.

Measuring GPU Usage with Vsync enabled is meaningless - at 1080p for example if your card can run the game at 120 with vsync off then enabling Vsync to lock at 60 will result in 50% GPU usage......

Just one screen. The goal might be to get 2 more of the same screen down the road. For that to happen though, I need this running smooth. Also, what does -novr do?

-novr disables Oculus Rift if you have one plugged in.

Yes, you are partly right, but you are discarding the fact that the GPU will only idle and reduce its usage when the frames reach the desired number. In this case, 60FPS. When I run any other game, the cards always boost their usage as necessary when the FPS go below 60. Whether they need to boost to 95% or just 80% depends on how much it really needs to achieve it. Once it reaches it, they go down to whatever is enough to maintain it at 60. In this game, they never even try to go up in usage to attempt to establish the desired framerates. They are not supposed to stay at 50% usage if my framerate is in the 30s. Also, if I disable vsync nothing changes only that the menus become ridiculously overpowered in frames.

Look at this picture for example:

208244

It is using all the crazy raw power at around 90% to draw 660FPS. If I enable Vsync. it goes down to 11% usage but maintains 60FPS and will increase if necessary to maintain the same FPS. This is the way it works in every other game I've played for the past 14 years.

There are a bunch of causes for low GPU usage:

1. Vsync as I mentioned when you have a lot of head-room over a target frame-rate (the 11% usage at 60FPS you give in the front-end is a good example of this)
2. GPU<->CPU Interlocking. This happens when the CPU tries to update a resource (like say some Geometry) while it is in use by the GPU - typically under D3D11 you 'lock' (map) the data, update it and unlock it. If some data the GPU is about to use is locked when it encounters it, it will need to wait for the CPU to finish doing the update and this will increase idle time.
3. The driver thread being a serialization point. When a game submits DX11 API calls to draw the various scene elements, these are queued and then consumed by the driver thread. This is true for both AMD and NVIDIA drivers. There is an absolute limit to the amount of calls that this driver thread can process depending on the CPU type and clock-rate - if a game exceeds the amount that can be processed per frame by this thread and the GPU (like yours) is fast enough to render all of these draw calls, then gaps (idle-time) will start to occur because the GPU is able to render the calls faster than the driver can provide them.
4. SLI inter-GPU transfers. With SLI as you know each GPU renders alternate frames. However, quite often with modern rendering techniques the *result* of one frames rendering must be used in the next. This is a problem because the second GPU is rendering the next frame - therefore in order to give the correct rendering result it must be transferred e.g. the GPUs must be synchronized. If the volume of the data to transfer takes longer than the frame-time then idle time will be produced while the GPUs wait for the transfer.

So pretty much if you have low utilization it will be down one of these. I'd like to ask you to run without Vsync for now and also I'd really appreciate it if you could test some things for me to determine where the problem lies.
I understand your frustration, but clearly a lot of PC systems get good SLI scaling and finding out why some don't is important. I understand you might have 'tried everything' but I need to go through this methodically - so if you help me, I can help you.

Is that a deal?

So (and bare with me!) there are a few basic things:

1. Can you provide a screenshot of your NVIDIA control panel with 'Manage 3D settings' selected.
2. A copy of your graphicsconfigdx11.xml
3. The NVIDIA driver version and also the utility(and exact version) you are using to overlay the GPU usage/CPU usage (our internal code has this stuff, but I want to be aligned with whatever you are using on my local SLI system)

Attached are all three. For point 1, please note I like to let the applications decide the settings. I'm a very "anti-super-tweak-everything" person. So I keep everything global and I like to just use the game's settings. I've only used the 3d settings in Nvidia to enable DSR and to switch the GPU to max performance. For point 3, Riva tuner comes with MSI Afterburner. This is the utility I use to gather the data. The versions are displayed in the screen. In addition, I'm using the one and only driver for the 980 Ti at the moment, 353.06. It's also displayed for both GPUs in the screenshot.

Also, I've just noticed the GPUs have a different Bios version. How does this affect anything at all?

I can answer that having different BIOS on stock cards will not have a negative impact. The only time this would be an issue is if you flash an overclock bios on one card and not the other. And it wouldn't be a problem, just not get full potential. My GTX770 Classifieds have Different BIOS on BIOS 1, but have the same BIOS on LN2. No difference in performance other than I can push the power limit more on LN2.

DSR 4x is equivalent to our AA mode "DS4X" but NVIDIA's version can be a lot slower - the reason for this is that when you use DSR 4x it is applied to elements of the scene like the post-FX (depth of field, heat-haze, post filters) that gain little or no benefit from the increased resolution. The DS4X AA mode only applies down-sampling where it is of benefit - e.g. the 3D parts of the scene.

However first things first. With SLI enabled and NO AI.

1. Capture a screen-shot with your normal Ultra settings.
2. In the performance options - set detailed grass to 'off' and reflection and environment map to 'High' (not Ultra as you currently have). Capture a screen-shot.
3. Post both screen-shots (make sure you capture both with the overlay enabled with GPU stats - not red please!))

It's not a difficult process to do and with GPU-Z you can actually save the bios from one and flash to the other using nvflash. If you decide you want to do it, hit me up and I will be more than happy to walk you through the process.

I used SLI during the roughly 3 years of development builds.

During that time I experienced with several video settings in pCars but has Nvidia SLI support only came in the very last stage of development not much could be said then.
Nonetheless, it seems that pCars ir poorly optimized for SLI and I tried different video settings to see what suited better.

I found that the higher the AA setting used the higher the GPU usage.

Also I found that using -skipcrowds -dx11mt in launch options contribute to a better SLI experience just as not using detailed grass, detailed grass off, therefore.

Here are some screenshots with the following settings (click on the screenshot to see in full resolution).

I wasn't using DSR before. I was using a crazy nVidia CP setup to override all AA. I set my nVCP back to default with the exception of Power Mode. In game I use DS4X. No FXAA. No SMAA. Reflections/Enviro Map = Medium. Car/Track Detail = Ultra. Shadow Detail = Med. Texture Filtering = 16X.

With GTX 770 Classifieds 4GB is dual SLI I am running a pretty consistent 80 FPS. I was getting a little bit of TDP, but that is because I was experimenting with no space between my cards and I haven't turned my AC on yet. I just re-configured my card spacing to put a gap between them to help with the temps (ACX SUCKS!) So I think that will solve that bit of issue. But on Oulton Park with no AI was was locked at 80FPS. (I think I might have it capped, will check). With 12 AI I was at 80FPS up until my top card started to temp throttle. Then it dropped to a lowest of 74FPS. But I can report that that both cards were running pretty consistently at 90-93%. And again the game has never looked that good.... No in the rain it is still absolute crap. But I will take this so far!

Ok Cool - you have 107FPS VS 64FPS with just 3 changes to settings, 2 from Ultra to High and 1 to off... !!

In theory now we've *lowered* settings yet the GPU usage is much higher, which is the opposite of what you would expect e.g. We have given the GPU less work to do(!) but it's somehow more busy... (less idle time... which of course means one of those reasons I outlined above must be the problem)

So the next test:

With the lower settings (107FPS), I want you to increase the detailed grass setting back to the Ultra setting and then post another screen-shot. If it does have a significant impact then please post another screen-shot with the detailed grass setting at High.

I've posted numerous graphs on this thread with various testing results all of which you are being asked to do now, and I've heard absolutely nothing back from the devs. Your wasting your time being asked to do all of this, unless of course you enjoy being a beta tester..

You seem to be both complaining that the devs didn't help and that they are now helping, which doesn't make sense.
I've been thinking this morning - this is rare. SMS is _actually_ helping people. Actual team is responding and helping. And Ian's entertaining posts - I get healthy dose of humor every morning by checking them. I seriously don't know where those guys find sanity and strength while dealing with so much negativity.

I have a humble suggestion to dissatisfied customers: go try modern completion on PC (in simulators, I won't call names). I suspect that might change opinions of many people. None of simulators are perfect, but IMHO pCars is currently in the lead in terms of completeness and optimization. And, it is made with love, and it shows.

@Ian Bell, that's right ban him and everyone else who has purchased a "finished" game at full price, only for them to discover the game is still in it's beta stage!!!!!!! I have spent hours upon hours testing and posting results and graphs for YOU to look at, have you spoken upon this issue? NO.

You release a unfinished game and charge full price for it, then when people complain about the bugs you ban them. Pffffft..... what a company.

How pathetic is your comment "........and the guy who liked it". What a child!!!!!

You can't even ban an individual from your forum, let alone finish a game!

So with SLI your motherboard RED slots run at 8x - compared to 16x say for X99 motherboards, so you have the nearly highest through-put GPUs available (to human-kind!) but half the bandwidth to each card. So that's a potential bottleneck and might explain some of the variability.. but let's continue to investigate.

I've learned throughout the years that the 16x to 8x makes a very very minute difference in FPS. I "researched" this extensively the day I decided to go SLI. At most 5FPS will be lost. I'm sure the 8x is not as direct an impact as simply halving the values.

It's not really an improvement since all opponent cars were removed. I expect the FPS to go down to crap the second I bring it back to 29 opponents. The percentages to the immediate right of the temperatures are the GPU usage.

If you confirm the reproduction changing the single setting from High to Ultra a few times gives a consistent result, then at the moment it would seem that the single change results in a 27-35% speed-up(!). I really appreciate your time with this, but firstly ask yourself if you 'expected' a single setting to have such a large effect? So bare with me asking you to test a few more things - expecting the FPS to go down with 29 opponents is an assumption. The computer you sit on is based on the Scientific Method.. and every component was built on not assuming anything, but dilgient (un-biased) testing and that method is responsible pretty much for everything in the modern world. So... that's what I am applying - I presume to know nothing about your PC and the instructions I give are to test various theories... Do we still have a deal?

I perfectly understand. I'm an aerospace engineer and also familiar with the systematic approach we are doing here. I'm not trying to assume; I'm just speaking from my experience that adding more to the cards to process will most definitely decrease the FPS. In this case, adding the cars. Like I said before, don't be alarmed when I speak my mind. It's never intended to discourage the organizational thought pattern you are executing here. I know how things can go. I know this is a computer program and I also know you are the expert.

Okay, FACT: When I run everything at ultra (as we've been doing per your instructions) the FPS ≈ 60 and GPU USAGE ≈ 65%, and when just the reflections setting itself, is lowered to high, the FPS ≈ 93 and the GPU USAGE ≈ 88%.

I'm trying to get a friend to test his ultra/high settings on reflections to see if his performance gap is as wide. Can anyone else around here confirm if this is the case as well?

Okay! (fellow Engineer - but in Aerospace, where testing is 10x what we do with games, so respect!). We've estabilished that this particular setting change is a big win - but this is *not* conclusive because it's a single track/start-grid. I'd like you try the reflection high/ultra test with Brands Hatch GP and post a FPS comparison or screenshots. You can try a few other tracks if based on that result you feel you need more data.

SLI GTX 980 x2 1440p - If anyone's interested, I think I have FINALLY found the best settings...!

At 1440p with Full Rain weather conditions, 29 opponents, Brands Hatch Indy, BMW M3, I am getting an absolutely consistent 57-58 FPS (on all cameras), never dropping below 56 FPS. This is with all in-game visual settings maxed-out *except* the following:

AA: DS2M
FXAA: Off
SMAA: Medium
Reflections: High
Detailed Grass: High

The FPS line is so straight on the MSI Afterburner FPS graph that I think ProjectCars is capping at 58FPS even though my start-up options set the limit at 60FPS (see below). Or maybe there is some measurement difference?

Is this a good performance? I think so, but I'd like to hear others' experience with 2x GTX 980 in SLI @1440p. I have played around with the settings for the past few evenings, leading to various crashes and often frustratingly and inexplicably low FPS, and have come to the following conclusions:

1) Let the NVidia Control Panel (NVCP) do its thing.
Set NVCP to use the default ProjectCars profile (incl SLI settings). Do not change anything. Do not use V-Sync, even adaptive.
In the NVCP SLI setup tab, force PhysX onto your 2nd GPU, but otherwise leave as is - i.e. "Max 3D setting" (=alternate frame rendering).

2) Let GeForce Experience "Optimise" settings the way it wants, just once. Then close GeForce Experience.

3) Run Project Cars directly from a desktop shortcut pointing to "pCARS64.exe" with the options: -dx11mt -fpscap60. This forces DX11 multi-threading and caps FPS at 60 (my 27" IPS screen is only 60FPS)

4) Now change the in-game settings to max everything except the items listed at the top of this post. I think this is the best compromise for 1140p where heavy AA isn't needed.

Do not let GeForce Experience "optimise" things again, do not launch ProjectCars from GeForce Experience or directly from within Steam - only use the desktop shortcut with the command-line options (the desktop shortcut works for Steam versions too).

That's it. Runs silky smooth 57-58FPS, even in full rain or rainstorm. In the past few days I have tried many many other combinations of visual options and they have all either looked worse than this, or crippled the framerate under SLI (sometimes even when going to options that ought to be lighter on the GPUs, inexplicably).

I have to say I *LOVE* this game, especially with my new Logitech wheel and pedals :-)

My setup:
2x GTX 980 reference blower cards (one PNY, the other Zotac) overclocked by 200MHz to 1440MHz and memory overclocked 100MHz
Intel i7 4790K overclocked to 4.2GHz (stock cooler)
MSI Z97 Gaming 5 motherboard
16GB 1600MHz RAM
1TB HDD 7200RPM
Windows 8.1 64bit

Project Cars v1.0.1.4

Ok keep the grass and env map at low for now but stick with DSR.

Now test again with 0,10,20 and 30 AI. (Player last starting position)

NOTE: I've added shadows to the OSD to see if it improves the quality... (Edit: Disregard, It throws off the FPS by about 20 which messes with the results. I'm keeping it off.)

Ok, Back to DSR 4K, FXAA HIGH, AA OFF, SMAA OFF; Everything Ultra except for: Reflections = High, Env = Low, Grass = Low (Azure Circuit 14:00 Local, Heavy fog with rain).

0 Opponents = 121 FPS
208517

10 Opponents = 81FPS
208518

20 Opponents = 69FPS
208519

30 Opponents = 64FPS
208520

Huge drop from 0 to 10. Why's that? Also, the GPU usage keeps dropping the more cars I add. CPU seems to stay around the same usage.

I hate my first post here to be a bit of a whine but I'm rapidly losing patience with the performance of this game when it comes to SLI.

My Specs:

Intel 4690K (4.5Ghz)
8GB 2400mhz DDR3
Asus Strix 970 SLI (@1210 core, 1390 Boost, 7.5GHZ Memory)


Here is an example of what I mean using the following settings:

http://i.picpar.com/7Xyb.jpg

..not exactly pushing it for 970 SLI is it..

Start the race (only 12 cars BTW) 60fps:

http://i.picpar.com/8Xyb.jpg

GPU usage well within limits

..restart the race and this happens:

http://i.picpar.com/BXyb.jpg

Frame rate down by 15%, GPU usage down by 20%

TDP limits are also well within limits.

There is just no consistency to performance whatsoever...and I'm hardly even pushing my GPU's @1080p 'high' settings, I've spent the last 2 days trying every combination of Gfx settings but to no avail, it's just a waste of time TBH.

And this is just one example of how performance is all over the place from race to race, circuit to circuit, restart to restart...it makes it impossible to fine tune this game to give any kind of solid, consistent frame rate, and quite frankly I've had enough.:(

SLI support in this game is fundamentally broken.

It's alright for them to sell us a "finished" product at full price, when it clearly isn't finished, and when people complain they do not like it. What do they honestly expect !!

Edit:: The devs seem to think the gpu usage issue is system related or a bottleneck - the fact is the graphical settings are completely messed up. If you crank the settings to the max with vsync off, you get higher gpu usage, but the moment you lower the settings down the gpu usage goes down, thus giving less fps is some cases. If you have v sync off in any other game your gpu will work at around 100% usage regardless to what graphical settings you choose, but not with pcars, but yet they still insist this is system related. Heck, this is only one of the 100s of issues, the greyed out drive bug in MP is extremely frustrating , 6 weeks after release and I still cannot seamlessly join a MP race without rejoining up to 5 times. This is nothing other than a broken unfinished beta game - I guess they started to run out of money, hence why they released it in this state.

Can you imagine buying something from Amazon, then complaining because they sold you something which was supposed to be new but it arrived used, Or even better, buying a Amazon TV Box, then discovering a lot of features didn't work or were riddled with bugs, then the director of Amazon says "You're a nutjob" when you complain. It just shows what type of company SMS is, they have no respect for their customers, Ian Bell is after one thing and one thing only, your MONEY.

I've seen some of Ian Bell's (head of SMS studio) comments on this forum which are pure lies - I posted something in rage the other day, to which he posted a comment aimed at me - "You know our lead PC coder spent hours helping this guy personally last night. You don't deserve to mix in decent company." Okay, 1. Your PC coder has never helped me or even replied to any of my comments (even though I've posted pages of testing graphs for you to look at). 2. Your company is not decent, it's a mess and your representatives attitude is discusting! So what you talking about? Your just trying to cover up your mess with lies.

Everyone who feel's like they have been robbed by this company should take a trip to trading standards, after all SMS have sold something which is not as described, not to mention false advertising pre-order DLC content which some never even received, so they claimed it was a typo on their website.

Please keep an eye around here and if you can help us further and you're willing to, please do as per SMS PC RENDER LEAD request if he ask for. We would truly appreciate this.

I'm away from my laptoo (on mobile now) But I'll will help you directly to get better performance meanwhile this gets troubleshooted in this thread. This will be over PM to keep this thread clean. PM me tonight so i don't forget.

Okay so people who put in many tiring hours of troubleshooting (100+ posts over the course of a week), posting graphs and what not; then finally when a dev pipes up 6 weeks later he doesn't even acknowledge the member who put all the effort into posting all those testing result graphs for YOU devs. This member gets pee-ed off that the dev has nothing to say about the testing results, thus still being in the same situation for the past 6 weeks (not being able to play the game), which causes the member to post a rage comment then gets banned for speaking the truth.

"Lets ban members who provide a lot of useful debugging graphs for the devs to just fob them off and call them nutjobs" - Pffffftt, shocking company!

PC biulds are so diverse a custom bios is the only way to get this game running for some. Imo
Alot of people I know have built thier PC for this game!
I have a friend who plays another game on his ps4 and is getting blue screening with no error code, Sony can't help him, he's tried everything to rectify it, but no joy. Support can only go so far, maybe handing the PC over to one of those private computer engineers could solve the issues with running this game.

I can't name any game forum where members get banned for providing their honest opinion on the game especially after providing pages after pages of testing results. If the developers are willing to help with issues, then why do they just ignore the original poster who has provided over 100 posts showing graphs etc? If the developers are willing to help, then why do they request members to be banned if they post a rage comment after not being acknowledged for all the testing they done for the company?

Just wait for the next patch. Each time the game is improved more stability is made. I would take it to a specialist and get a free estimate to what the problem might be, then use that to get a refund if its software related. I consider myself a engine diagnostic tuner, but theres times when a second pair of eyes solves problems! Getting yourself upset is not a good thing to do to the people around you. It seldom helps.

I'm not upset, the fact is they cannot take a bit of criticism and honest opinions from their customers so they ban them and anyone who likes the comments. Imagine Amazon banning customers who review their products negatively!!! This is just a bad company from the ground up. First they release a unfinished game because they clearly ran out of money to fund the project, they then false advertise pre order dlc causing some customers not to receive this dlc, they then ban people who provide good useful testing results who eventually get fed up due to no acknowledgment from the devs. SMS are the ones who have dug themselves into this hole, and it's clearly getting to them, hence banning anyone with a negative opinion.

Indeed but not quite - let's not forget that the AMD/NVIDIA driver thread takes another whole core and then the actual main game e.g. AI and render calculations on the main core.... then we have audio mixing, real-time engine sound generation and many other threads over all these CPU cores...

NOTE: I've added shadows to the OSD to see if it improves the quality... (Edit: Disregard, It throws off the FPS by about 20 which messes with the results. I'm keeping it off.)

Ok, Back to DSR 4K, FXAA HIGH, AA OFF, SMAA OFF; Everything Ultra except for: Reflections = High, Env = Low, Grass = Low (Azure Circuit 14:00 Local, Heavy fog with rain).

0 Opponents = 121 FPS
208517

10 Opponents = 81FPS
208518

20 Opponents = 69FPS
208519

30 Opponents = 64FPS
208520

Huge drop from 0 to 10. Why's that? Also, the GPU usage keeps dropping the more cars I add. CPU seems to stay around the same usage.

So, this drop from 0 to 10 - it's actually rendering 20 cars, because of the reflections, but that does seem a bit high. But again, bare with me - the 30 AI case is at 64FPS with low env-map. So could you repeat that with medium and high env-map with all the settings the same - and post screen-shots. This will help be diagnose whether it is CPU or SLI transfer bottleneck.

I read the whole thread - there is a bottleneck. Stop for a second, if there wasn't an issue with the driver, some PC system specific issues or our code, then everything would be at 100%. So what do you have to lose here but engage rather than be disruptiv and help us, NVIDIA or the community to diagnose the issue? I just don't get the negativitiy - happy to take the responsiblity for not nailing the now nearly 200,000 PC systems that are running our game to 95% instead of 98%.

Ok thanks - that last set of tests has effectively ruled out:

>> 4. SLI inter-GPU transfers. With SLI as you know each GPU handles renders alternate frames. However, quite often with modern rendering techniques the *result* of one frames rendering must be used in the next. This is a problem because the second GPU is rendering the next frame - therefore in order to give the correct rendering result it must be transferred e.g. the GPUs must be synchronized. If the volume of the data to transfer takes longer than the frame-time then idle time will be produced while the GPUs wait for the transfer.

However it does seem that the Ultra detailed grass setting is still causing 4) at least on some systems. So lowering the detailed grass setting to High should be the first action for SLI users experiencing any form of stuttering.

I need to do a few tests here next to see if I can reproduce the reduced GPU usage as the number of AI increases. Meanwhile if you could repeat the 0,10,20,30 AI tests again in dry conditions (Reflections High, Envmap High and grass off, everything else Ultra).

I've had the same thing with my GTX 980 SLI occasionally, and when that happens if I quit and restart the entire game it usually fixes it. I've noticed sometimes when that happens when I look at my GPU monitoring software usually something happened and for whatever reason my GPU was running at a slower clock speed. Restarting the game though usually makes it go back up to speed, but I have had to restart my entire PC before when just restarting the game didn't work.

Restarting the game though usually makes it go back up to speed, but I have had to restart my entire PC before when just restarting the game didn't work.There are a few triggers which 'throttle' the GPU speed on Nvidia cards and the newer they are the more sensitive as far as I can tell. The 2 common ones are hitting the thermal threshold and/or the TDP limit. In either case, the GPU is clever and goes in to self protect mode, reduces the GPU speed and trundles on. unless it is reset it seems to remain at the lower speed. Restarting the game will put the Graphics driver back to 2D mode and then back to 3D mode effectively resetting the graphics card/driver.

A good way to observe this and any other GPU throttling is to use the graph function of monitoring programs such as MSI afterburner or EVGA Precision X and look at coinciding events... monitor GPU temperature, Power % (TDP) and Core Clock Mhz (GPU speed). You can also monitor the triggers to see when they are tripped, with Afterburner, (not sure about EVGA) they are labelled as Temp Limit, Power Limit and Voltage Limit if they go from 0 to 1, then they have been tripped, no question!

>> 4. SLI inter-GPU transfers. With SLI as you know each GPU handles renders alternate frames. However, quite often with modern rendering techniques the *result* of one frames rendering must be used in the next. This is a problem because the second GPU is rendering the next frame - therefore in order to give the correct rendering result it must be transferred e.g. the GPUs must be synchronized. If the volume of the data to transfer takes longer than the frame-time then idle time will be produced while the GPUs wait for the transfer.

However it does seem that the Ultra detailed grass setting is still causing 4) at least on some systems. So lowering the detailed grass setting to High should be the first action for SLI users experiencing any form of stuttering.

I need to do a few tests here next to see if I can reproduce the reduced GPU usage as the number of AI increases. Meanwhile if you could repeat the 0,10,20,30 AI tests again in dry conditions (Reflections High, Envmap High and grass off, everything else Ultra).

4K DSR, FXAA High, SMAA OFF, AA OFF, Reflections High, Env High, Grass Off, Everything else Ultra (Azure Circuit, 14:00 Local, Light Clouds).

SMS PC Lead, let me know when we're done with this batch of tests so that I may proceed to install the new Nvidia driver. I'm hoping to get some improvement with the drivers so I can finally play the game.

Regards!

I thought I'd seen something as part of my imagination, but it turned out to be true. I did some googling and found some threads on this:

The hud is reducing about 20FPS. According to the screens below, it's the minimap, position display or a combination of both. I'll leave it to the software engineers!

FULL HUD OFF = 105FPS = GPU USAGE 86%
209233

FULL HUD ON = 86FPS = GPU USAGE 73%
209234

REARVIEW OFF = 86FPS = GPU USAGE 73%
209236

Minimap, Position Display and Rearview OFF = 103FPS = GPU USAGE 86%
209235

TELEMETRY ON = 95FPS = GPU USAGE 79%
209237

This was spotted and reported during WMD testing, but I could not remember off-hand what caused this drop.

Possibly not the exclusive cause, but "chase cam" suffers from fps drop with anything except the basic HUD that by default is found in the bottom-right corner. With "ultra" track/car/shadows; "rain drops;" particles "low" in thunderstorm at Monaco with just my BMW M3 GT, my fps drops from 40 to 32 in chase cam on pole position start grid.*

Cockpit cam does not suffer from this, at least on my pc, fps stays at 38 in the above scenario.

*On Windows 10, build 10130 with default build driver and 1040 DLL files in pCARS root folder. I could not dream of using such high settings with that fps in Windows 8.1 in the rain!

I have 980s in SLI and the game utilises 30% of both cards on ultra. There is clearly an issue and it needs to be fixed. Lazy coding no doubt. Ill await an update or not play the game.

Thanks

*EDIT* I upped the SMAA to Ultra and the AA to D4X (Or what ever it is) and my performance increased greatly and upto 80% of the cards were being used. This doesnt make sense but im happy with it.

Interestingly if you view car stats in Solo Race the GPU usage goes to 98% on both cards and i pull in 125fps. Poor optimisation i believe.

I forgot to ask you. If you could, please trace back a little on this thread to my conversations with SMS PC Lead, and maybe try to replicate some of my tests with his indications and post the screens. I'm sure this would help them. Also, your in-game settings and Nvidia control panel settings.

I'm on the same boat as you, waiting for this to be fixed. Let's be hopeful! :cool:

Sure thing. Im off to bed now (In UK) but ill do some stuff tomorrow. Ill also post my settings ingame and you can try and match.

These are good things to test. Let's wait for SMS to see what they think of this.
