So when i open Osu! it shows a black screen if it's not V sync but i can press shift+click Osu!.exe and change it to V sync and then change it back to 120/240/unlimited FPS when playing but the problem is the cursor has a delay so you click compatibility mode to fix it right? well it just makes my Osu! open with a black screen but it does play sounds coming from the game pls help.
