Ok, since this issue seems to be a big thing again because of a recent driver update. I'm dropping this final message and locking this thread.
Please do these steps.
While osu is closed. Open your Start Menu or a File Explorer window and type %localappdata% in the address bar.
From there, find your osu! folder and open the osu!.pcname.cfg file with Notepad.
Set the following lines as such;
CompatibilityContext = 0
CanForceOptimusCompatibility = 0
Once you are done, save the file, and then launch osu!
IF you do not have that file, either because it didn't generate or your reinstalled to try and fix this issue. You can manually create a file, add those lines, and save it as a .cfg file. Be sure to name it correctly (osu!.pcname.cfg) Replace pcname with the name of your System/Windows User. You can check the file path to that folder to double check. It should say Drive:\Users\[user]\appdata\local\osu! use whatever is [user] for you. If you need more detailed instructions, or further help with making that file. Read this thread
