Installation steps
1. run installer directly(.NET 2.0 will be installed automatically with osu!), it will crash at the Publish... phase, don't let it exit before you backup the osu! installation folder(the setup will delete everything when continue)
2.run osu! normally and it should run *laggly* (cuz in DirectX mode), go to the settings and change to OpenGL mode & restart.
3.done , now you can change other settings to fit your experience(in my own test, 60fps is smoothest)
