View Full Version : Terrible framerate on AMD Crossfire setup

G'Day,

Wondering if anyone can help me, I have been looking forward to this game for a long time, and have nothing but disappointment since I bought it.

I tried the leaked beta several months ago and the game ran smooth as silk with all settings on high.

However, since the retail release has come out, I can barely manage 20fps with only 10 cars on the track with all settings on medium with no AA.

At the start of any race it looks like a slideshow, ie. 10fps, then whenever anymore than a couple of cars are in front of me it runs at 20fps.

If I play with no other cars on the track in clear weather, the frame rate will jump up to 40-55fps at times with the game set on medium settings.

If I enable rain the game drops right back down to 20fps.

My system specs are: Intel i5 4670K at 4.5ghz (liquid cooled), 8gb DDR3 1866 ram, 2x 3gb Sapphire HD7950's in crossfire, trying to run the game in 1920x1080. Logitech G27 wheel and pedals.

I originally had the 15.4 beta drivers installed, but have since done a clean uninstall of all drivers and reverted back to the 14.12 omega drivers, which made no difference.

Something doesn't seem right, the way the game is at the moment for me it is unplayable, and if I could get a refund, I would be more than happy.

Thanks,

If you ran the "Leaked Beta", you may have old Profile info that could be affecting the current release.

First thing I would try is delete the Profile, or graphics config as a minimum.

These are found in the Project Cars folder in My Documents.

Panter... For proper AMD GPU support, sadly, we will have to wait until proper better Driver support.

So Far, If you run Windows7,8,8.1, your best experience would be with 15.3 but don't expect 100% increase over single GPU or Magic Smoothness. It will take time for you to set it up in a way that it works.
So for you specially I would say:

1) Install 15.3 or 15.4 drivers
2) Set up LOW and MEDIUMs in VISUAL options inside PCARS. No more than that
3) DISABLE Detail Grass (or put it on LOW as maximum)
4) Try VSYNC on and off to find YOUR smoother experience.
5) Use Render Frames Ahead=1 to reduce input lag. =2 it should be smoother but with slightly more lag


Let me know, I'll help you out further if needed


EDIT: AND YES, as morgan said, Delete your profile from MyDocuments AND from Steam/UserData/xxxxxx/nnnnn folder (the pcars one!)

Thank you for the help.

I'll try that when I get home tonight after work.

No worries. But patience is needed for AMD users as we are. They're working around the clock to get a better PCARS support for us as far as I understand :)

I went through my Windows system last night and uninstalled all the crap I haven't used in a while.
Did a clean removal of the Catalyst 14.12 drivers, installed the 15.4 beta drivers again.
Turned off bloom, heat haze and tweaked a few other settings.
Game is running a fair bit better now, between 60-90fps with no other cars on track, up over 40fps now with 10 cars or so on track.
Whilst it is still far from perfect, I'll just have to be patient and wait for AMD to hopefully release some new drivers soon.

Please post a screenshot of your Visual Options (where resolution is) and I'll recommend you even further for the best performance possible with your setup

Cheers mate, here are my current settings.

Suggestions only for your system:

Visual FX
Bloom to ON (better lighting specially at night)
Global Specular irradiance to On
Crepuscular Rays to on (if you like that effect, I love it!)

/////
Performance
Texture Filtering to Aniso 8x (almost no perf lost in there)
AntiAliasin set to OFF .. and
FXAA to LOW - This is an alternative of running MSAA and none, should be similar performance, it worth the shot!
Reflections to LOW
Environment Map to LOW
Render Frames Ahead =2
Particles both to LOW


Try those settings, and report back if you felt it the same, faster or slower.
In my opinion, you should have similar/better performance with a better looking graphics (slightly)

Thank you for your help Aldo.
Much better looking graphics with those suggestions, and frame rates are also a lot better.
I am now running the game on Windows 10 Pro Insider Preview Build 10074 which also gave me quite a nice boost in frame rate.
Now at the start of a race with a full grid, it only chugs down to 35fps or so. However when racing the game sits anywhere between 55 to 105fps.
Even when raining with several cars in front of me it doesn't drop below 45fps.
I am sure it will only get better once AMD release some new drivers with fixes for pCars.
Once again, I really appreciate your help and am now enjoying the game immensely.

Regards,
Matt

Do you have any suggestions for settings based on my setup below?

Read the performance bit in here:

Try Medium/lows as suggested there, you'll find how much of an impact does setting have.

Just sharing some experience I had today with a AMD Crossfire setup and Project Cars:

http://forum.projectcarsgame.com/showthread.php?27449-AMD-Crossfire-not-utilizing-both-GPUs-RadeonPro-not-compatible-with-PCars&p=940042#post940042

In short, I had big issues, getting any stable frame rate with PCars when using Crossfire enabled.
Thanks to a nice user here who pointed me to the MSI Afterburner tweaking tool, I could finally monitor what exactly was happening with both GPUs when in Crossfire with PCars!

Both GPUs lingered at low usage and randomly were throttling the core clock speed, while Project Cars was severely struggling to barely reach 30 FPS at best.
I found out that a combination of using MSI Afterburner, the CCC overclocking functions and enforcing Crossfire: 1x1 in combination with some nice but still conservative in game graphics settings, Project Cars runs now beautifully.

I hope this info can help one or the other suffering AMD GPU user who has had no luck yet with their Crossfire setup.

I have to concede my 5870's are exceeding my expectations with 15.4.1 and 15.5.

NOTE 15.4 drivers are totally screwed for crossfire so if you are using those you need to replace them with 15.3 or 15.4.1 as a minimum.

Using the -skipcrowds launch option helps a lot as it save ~200mB of VRAM, important as I only have 1Gb, and it saves a lot of draw calls for all those 3D people unblocking your CPU until AMD's drivers become more efficient on the CPU side.
-fpscap 63 also seems to smooth out the frame times, I guess because in the easy times the CPU->GPU buffers empty out a little giving some room for when things get hectic. Without a frame limit the CPU is simply sending data as quickly as it can and the buffers are likely always full. Motion blur is a bit of a frame rate killer too!


30 cars at the back of the grid at Zolder and I have 50fps, with the settings below and locked to 63fps most of the time. This is stella compared to a month ago, where I could barely drive solo at Zolder on much lower settings. Rain forces me to drop reflections and env map to low, but living in the UK I'm just happy to see the sun and drive in the dry.

Great news. I can state as a fact that there's much more to come from AMD.

Any insider tip for guy who busted his but testing AMD drivers??? 8-) :D :P

I might be shot by someone called Roy, but when Windows 10 and DX12 hit, well, it's going to be fun. Our engine loves it and AMD machines seem to prefer both...

For the remaining mortals... I must note that AMD 5xxx and 6xxx series always performed better than Rx yyy and 7xxx.

I'll be screwed with W10 though as I'm sure the 5XXX support will be dropped and DX12 will be a none starter :-(

This is a great command for people who struggle with VRAM and those pesky CPU calls when you really don't need them as the CPU is busy enough with all the eye candy and a full field ;-)

I have tested Yesterday how I can benefit from this command (mainly to free up CPU, as VRAM is plenty with 2x 3GB).

A tip for the people who want to test if they can benefit from the "-skipcrowds" command: Test this on any Hockenheim track version - once you enter the big motodrome with all those huge grandstands full of people it really is a stress test for this command.

If your CPU is already struggling with a large field or a lot of PP effects when racing under normal condition the Hockenheim motodrome from entering to leaving after the first corner is the ultimate test.

In the end for me it helped only very, very little and freeing up CPU by disabling detail grass had a much bigger impact for me + I see those beautiful crowds cheering.
