I’m not doubting your conclusions based on your hardware but I want to point out one area that you haven’t optimized. In this sim, the best results are obtained when using Windows Mixed Reality OpenXR runtime as opposed to Steam’s. Since you’re running the sim using an Oculus headset I know you’re using Steam. I have the capability to use both OpenXR via WMR and Steam. I can tell you it’s night and day. WMR greatly outperforms Steam in this sim.
So when you state that MS/Asobo are lacking in VR, I don’t think they’re lacking as much as you. I agree it could be better but I think you’d be much happier if you had a headset capable of running the sim via WMR’s OpenXR. I have a Reverb G2 running on a 6900xt and I’m totally satisfied with the visuals and performance. Actually since DX12 and FSR2 got implemented I’m totally impressed.
