I’ve never changed any settings in Nvidia control panel. DX11 performance was probably 15% less across the board so I didn’t even continue with any tested and stuck with just DX12.
I agree - the 3090Ti is more than fine for this sim. VR seems to be the only thing taking advantage of the 4090 so far. The shocking thing to me is I see less performance in 2k on the triple screens, where I figured I’d see a boost due to driving all the extra pixels. Maybe as the drivers mature things will improve.
