In my opinion this question is going to be one that each person will have to answer themselves. On my Reverb G2 I’ve gone back and forth on just about every config imaginable, and I have finally come to the conclusion that a 100 Render Scale in OpenXR, then scaling down in the sim to my best performance is the best for me right now. Only because I have other games and apps that don’t have this issue, so I want them to have the best resolution possible. I try to remember that old I.T. rule of never changing the whole system for 1 app.
Things will improve in VR I am sure, but right now I have to take a break from this performance chase and just enjoy the sim the best that I can.
