I’ll join many others here and add that I find the experience smoother directly via WMR/OXR rather than SteamVR with the G2. There is still the possibility there is a difference between AMD and NVidia GPU here, but I’d be surprised it is because AFAIK SteamVR is using the NVidia OpticalFlow lib for the motion smoothing (Oculus is using the same), and this uses the Tensor Cores specifically to tap into otherwise dormant silicon.
I’ve posted my latest findings with the G2 and SU5 here for reference:
