Hello. Recently I've updated to GeForce 6150SE nForce 430.

After this update, which was mainly done for another online game I play, OSU has never been the same. I get the error in the title and whenever I click yes to switch to OPENGL I get so much unbearable lag. I can't even click and change the options the lag is so bad.

If I click no it does not start. I've tried running as an administrator and it only worked once.

I've reinstalled OSU 2 times. After reinstalling OSU would work just fine, but once I would close it and restart it some other time once I've gotten bored, the error comes up again.

I do have DirectX 11 installed. This is so frustrating.

Thank you! It's been fixed. With OPENGL OSU takes a lot more memory so I had to close some unnecessary programs that were running that I didn't look into before since it had never been a problem.

I'm glad that helps you but it doesn't help me. I closed everything I could and it is still laggy in OPEN GL and if it is off it won't open. FML.
