I used to be able to run 31 ai @ 60fps no matter what it was or how it was setup, now I can't get anything at all. What happened? I'm so confused. I need help because this issue has me lost.

What are your PC specs?
What LFS version did you use when you ran it at 60 FPS?
Maybe it’s using your integrated GPU instead of a dedicated one?

Maybe a problem with the graphics driver
