When I set custom resolution to 1280×1440 with CRU, my monitor becomes scrambled in game when I tried it. I know windowed mode may solve this, but the resolution is unavailable in windowed mode. I am tring this in Fallout 3 at the moment. Is there anyway to make the custom resolutions appear in windowed mode for this and any other titles I may try in the future?
Anyway I found a better way to enable higher resolutions. Virtual Super Resolution in AMD Radeon settings. Higher than my monitors native resolutions and zero issues. Thanks anyway.
