I switched from a CRT Monitor that was very accurate to LCD panels, this is the 2nd panel I own and I just straight went from 99% acc to like 80%, recently I found out HDR makes reading easier, so I found out if I play window borderless I can HDR but the performance is very choppy, game doesn't go over 160fps on a 5800X3D + 3070Ti combo which is evidently not acceptable. I also tried a program that is meant to force the app to go HDR but it didn't work, I guess its because how osu! works against cheaters disabling any external layers... Whatever is the reason I think osu! in-game options should give you the SDR/HDR option so those of us with an HDR monitor can enable it...
