When playing games in ExclusiveFullscreen, the game Dims/Darkens to a very very low brightness. At first i thought it was the new 24.5.1 Driver so i downgraded to 24.4.1 but it's still occuring. I have found a partial workaround doing Ctrl+Shift+WinKey+B to reinitialize the video driver but i have to do this every time I Alt+Tab.
I did some searching for a while, FullscreenOptimizations is off, GameSettings is off, and I intentionally switched to 10-bit color mode in the AMD driver assuming Windows was being weird and trying to auto-enable HDR. But I've had no luck, Does anyone know any further settings i can change to try and prevent the Brightness drop?
Effected games 7Days2Die, SpaceEngineers, Another player had the same issue in NoMansSky.
Edit: Turns out when I installed reshade, It turned on the AutoHDR plugin by default. So it was just me being stupid for not immediately assuming it was on.
