I Know how you feel, there is just something not right with the VR drivers. I have an oculus rift S and first I had problems with asw.
Now ASW is working, but there is a big but......It only works good if you hit the 45/40 fps or above......but with my 1080ti I can lock fps with the Oculus Tray tool on 30hz or even 18hz and I can fly pretty smooth in Microsoft Flight Simulator.
But with the 6900 XT 30 fps is unflyable.....This is a huge problem, huge....For example airliners are a problem in Microsoft Flight Simulator, they demand more fps and it becomes all stuttery altho I am above the 30fps....With my 1080ti I can't achieve 30 fps in airliners maybe 24 but it's smoother.....This card just doesn't seem VR ready there are so many problems...
Truck Simulator is just a big mess, I have basically a smoother experience in my 1080ti.
The fact windows mixed reality users can't use reprojection, I mean cmon.....Did they not test this?
At this point if AMD don't solve this quickly, I will sell my card really, I am just done with all the fiddling. Nvidia is clearly a lot better in there VR support at this stage.
