Hi Guys,
I was running VRPerfKit before, and switched to OpenXR. After setting NIS upscaling, and similar FOVated rendering, I am happy.
Results are quite comparable, and without actually testing the frame rate can't really tell which is better. Will stick to OpenXR for now. (in game Toolkit settings are a plus)
