461.92 Nvidia driver, latest Oculus beta, latest Windows update on my Ryzen 5600x, RTX 3070, 32GB PC perform phenomenally well in XP11 and PCars 2.
As a benchmark - default install of XP11 is holding solid 80fps with 1.4 supersampling, in weather, with Global Traffic at 50%. No stutters at all.
Hard to argue with that. This batch of recent updates are good for VR performance. MSFS is in a terrible state right now.
