This occurred after I switched to Compatibility Mode on osu!.
After uninstalling and reinstalling osu! twice, it still didn't work. For problems with my drivers, my Intel(R) HD Graphics 630 is not working so I disabled it. That leaves my GTX 1050 to run my stuff. After the latest Windows 10 update, even Hearthstone ran at very low FPS. Help please.

Restart your computer and try running osu! again.

Update/Reinstall the graphics drivers for your GTX 1050, restart your computer and try running osu! again.

Open your osu! folder and look for a file named "osu!.pcname.cfg". Edit it in any text editor and set the line "CompatibilityContext" to 0 if it isn't already. Save the file and try starting again.

Method 1. doesn't work.

Method 2. has to wait till I get home with better WiFi.

Method 3. I don't have such folder. The closest one is "osu.cfg". With that being said, there's no "CompatibiltityContext" when I open it in Notepad. I can send the contents of the file if you need it.

I'm not getting a CompatibilityContext either in my files

Astahn the file called osu.pcname.cfg is replaced with your actual pc name instead of the actual name pcname.
