Hello,
I have a other problem. The game without vr do use corectly and nice.
If I start a VR Game, I come in the menu, I do start a race and I can play. The graphic is realy very nice, I have no jitter effect if I look left or right (maybe a little in Monaco). The driving makes me very fun. But maybe after 20 minutes, the game crashed and do closed it. The temperature from my system is normal. I have make a test with full fan speed on CPU, Case and Graphic-card. The same problem. And yes, steam vr is open (new install and start before game start).
My system:
Ryzen 7 3700X
RAM 32 GB DDR4
RTX 3080 Ti
RIFT S
Logitech G29
