Just popping in to say thanks for this. SteamVR had decent frames but stuttered every now and then, OpenXR is smooth as butter! When MR is on frames drop to 45, then 33, then 18 ish tho. So I have MR off and have nearly constant 45fps. Much better clarity and a bit of performance increase with foveated on. Have ghosting on fast movers, but with SteamVR all of the terrain was ghosting.
Ryzen 3600X, Nvidia 2070S, 32GB RAM, Reverb G2 on 100% without MSAA.
