Hi chaps,
I found a problem with the newest Nvidia driver as I couldn’t get past 50 fps in pcars 2 with a 1080ti regardless the graphic settings, even on low.
So I recommend installing the previous driver.
Hope this helps somebody.

Hi there, do you have any other games you can test this on please? Interested to see if this is on all games or only on pcars?
Thanks

Not really as AC and iRacing are not this demanding.
I had some problems with iRacing‘s fps but after a clean install of the 388.31 they were gone.
The only other thing I can say that the Time Spy benchmark was sometimes 1k or more lower in points but after a clean install they went back to normal.
It’s really odd.
that really is odd… only affects 1 game you know of? can you tell me if Pcars has a vertical sync option? or additional Super sampling in the game video settings …( im not talking about Piplay render slider, im talking about game video options) if so can you turn them off and use the piplay render to set the quality instead. then tell me how that fairs?
thanks

Yes only one game. It has both. I deactivated both aswell with no different result. I‘m not gonna to install the driver again. As you might know: Never change a running system
Also it took me 4 days to figure it out.
good on you for figuring that one out!

Hi Team please note that Nvidia driver 388.31 appears to have some negative effects in Pcars. It does not appear to affect any other games. are you able to please test Pcars with that driver to try to establish what is causing it and if the FPS can be improved?
Much appreciated.

I may need to discuss this with Bacon and R&D team. Thanks
Hi Guys,
I ran into some strange problems again, this time with the 388.13 driver.
So I closed every software in the task manger which isn’t necessary for win to operate.
Then I run 3dmark Time Spy, result: 9112 points
2nd test I started PiPlay 2.5 (latest and downloaded from the website here), result: 8646 points
3rd test I closed the all PiPlay processes, result: back to 9147 points.
I will run some test with older versions of PiPlay now to see what’s happening.
Question is why is the PiPlay software eating up so much performance and causing for example Project Cars 2 not going above 45 fps, no matter what settings.
So after another couple of hours of testing it looks like Piplay is causing the performance to drop.
To make sure steam vr is not causing the problem, I installed a new steam and steamvr in a different folder. Also the in one of the threads recommended Nvidia driver 384.94.
Then I ran the a test with newest PiPlay and steamvr and one without in 3DMark Time Spy, the difference between those two test were nearly 1400 points.
After the deinstalled PiPlay and installed the 1.1.92 version. And look at this it’s back to a normal.
Is somebody of the 1080ti owners willing to test this aswell?
Hello, @Messiah866 We’ve done the test and analysis, and it’s mainly consumed in the Piserver process, which takes up 10-15% of the CPU, and this process is going to send the render data to the screen, which should be a normal range. (Steam similar process would consume about 20%)
Hi @Matthew.Xu,
thanks a lot for testing!
that’s strange because for me it was the GPU which went down in performance even though I didn’t use a VR game and with the steam render there is a lot less performance loss (4%)
There shouldn’t be a difference between the normal 4k and the BE version of the headset?
