It would be interesting to see your test with one monitor.
I have a 4K monitor for the sim, and a 2K monitor for other programs.
Also, I’m puzzled that your Render is reported as 1707x960 with the settings I listed. I would expect 2560x1440. Maybe that has something to do with the 3 monitors running the sim?
I do see that you are running DX11, while I’m running DX12 / DLSS / Quality, so your settings don’t quite match mine.
Having a current DLSS version is helpful, even if you are using TAA.
