    very encouraging with everything maxed out (since I personally think some settings/effect are unecessary), especially in those terrible conditions.
    Thanks for the feedback.

    As you said, unless you play regularly at 4K or use VR, there is not point in even thinking about getting a 2080Ti.
    Other cards have obviously better price/performance ratio, but it means nothing if you can't maintain the target framerate in VR.

    I'm still wavering. I definitely need an upgrade (especially with the larger fov headset coming by the end of the year), but I know that it would be wiser to wait for the next gen, especially if it's using 7nm (which should provide a decent boost as every time there was a change in the manufacturing process).
    AMD should be launching a 7nm series next year, but they usually doesn't target the very high end gaming market, and it's obviously too soon for nvidia to announce anything related to the next gen (even if the launch of the Ti model for the get go could mean there would be no "simple" upgrade next year as they usually do ... well it's also due to the fact that they could launch a new gen without any hardware overpowering the previous gen).

    Solid 45 fps (doubled to 90 with ASW) with all details at max at Long Beach in stormy night. 24 car grid and supersampling at 1.4.

    I actually had to use performance HUD of the Oculus debug tool to see that it wasn't real 90 fps. Something has evolved in asynchronous space warp, as I didn't see tearing in the usual places. Or maybe that has happened earlier only when you go under 45 (to 35, as it did at least in some point of the development, which looked very ugly).

    My old display adapter was Titan X Pascal which is approximately on par with 1080ti, just couple of percent slower. Compared to that the FPS boost in VR seems to be considerable.
    In order to maintain 90fps with my 1070, I have to run 1.2SS, low MSAA, and pretty much low everything else....

    But with ASW, my 1070 can run most settings on high and 1.3 SS. (Detailed grass and enhanced mirror are off though)

    Comparing ASW settings, (45FPS) the 2080ti doesn't seem like *that* big of a jump.

    I wonder if the 2080ti is just missing 90fps lock at max settings where my 1070 is barely over the 45fps mark with high settings.

    A fair test would be to compare in equal conditions (the worst track would be Monaco but I'm not sure the AI would handle that well the track in those perilous conditions ... so Long Beach is probably the closest as an urban track) with the same settings (I wonder if @MrTulip also maxed out grass & mirror). But since we don't have the exact fps number (as I said it's very inconvenient playing without the reprojection failsafe), we can't say were the 2080Ti is between 45-90fps.

    There is also the fact that pcars use a proprietary engine, which will hardly implement features for such a limited set of GPU (in case of nvidia 20x0 series : Variable Rate Shading and DLSS) considering the amount of works necessary.

    My wife had nausea issues when she tried PC2 in VR, I considered upgrading the GPU just to hold 90FPS and see if it helped her, but since it's just a matter of turning down the settings to get 90FPS for her to get sim practice, and I am fine with ASW for both practice and game play, I don't think the new GPU money is worth the eye candy.

    The game looks pretty good with high settings.

    Of course, even I am quite satisfied with a mix of low & medium settings (I wouldn't be against a little more in some more area but as I said earlier, I clearly think some visual features are necessary), even if I am constrained to dry weather with my hardware.
    What I meant is, it's not fair to compare between both gpu if you're not using the same settings/conditions.

    Yes, I had the mirror and the grass maxed too. I've only disabled the god rays since Oculus Rift has them plenty enough by design.
    MSAA was on High and SS at 1.4 (later settled for 1.3 because it looks better to my eye).

    It is difficult to measure stuff in VR. With ASW you tend to notice anything only when the FPS goes under 45, because of the tearing artifacts of ASW become so obvious. So my experiences are subjective to my own system and differences between Titan X Pascal and 2080ti.

    I can definitely say that exactly the same conditions the former did not manage constant 45 fps (90 with ASW on) and 2080ti does. It was very clear that day time driving with Titan X Pascal was ok in the rain, even with full details. That and 1080ti are very powerful cards. Sometimes some stutters in the middle of the pack during the first lap. Starts always from the back of the grid of course. Also some stutters when the weather assets are loaded from the disk when the weather changes. (I think. The GPU still has to be very heavily burdened for this to happen so it is not just loading stuff from the disk into memory alone.)

    But adding night driving to the mix is what completely shatters the camel's back. Rendering the night time lighting has always been the biggest resource hog in VR in PCARS1 and 2.

    Night at Long Beach, lots of particles (rain), full details, big field of cars, and there is no way anything else than 2080ti runs constant 45 fps in PCARS2. And no single graphics card on this planet runs real 90 fps with those details in VR. (I don't think even Volta does.)

    Earlier I did test turning off SS but not touching any other details, and I got lots of headroom in rendering according to Oculus performance hud. But not enough for automatic ASW to switch off and drivers go to 90 fps. Briefly turning ASW off manually showed me the frames at 60 - 80 fps, but I didn't follow it long enough to see how stable it was as it was horrible to watch (ASW and its equivalent in Vive really was a game changer in VR).

    I'm sure real stable 90 fps stable can be done with lowering settings, and I'll try that in coming weekend. It will be interesting to see how it goes.

    These settings get solid 90 for me any TOD or weather ! Maybe you can just work up from here .

    i would say, yes. But.....

    for a new PC for gaming, this is a very low peformance spec thingy.
    if you want to step up with VR in the future, you won't be happy.

    ^^^ yeah and if you are fine with no VR and certainly not max settings, I think you can still get the same configuration much cheaper, depending on where you live.
