True stretched AMD

Hi! Recently, I switched my GPU from NVIDIA to AMD (6800 XT). I can’t manage to use a custom resolution like 1280x960 @240Hz with Fill in-game, I can only use it in Letterbox. I went through all the same steps of creating the resolution, enabling GPU scaling, setting full panel, disabling all monitors, and yet it still won’t let me switch from letterbox to fill.

Any tips?

download more ram

U have to make a custom resolution first like 1280x882 because only custom res works then when ur in game u have to swap to 1280x960 in windows
