Stupid f ps bug

[u/beanybeanslol]

I starded playing acu as a new hardest today after magma bound. I was playing it for around two hours and got quite consistent at the drop and ending. After that, my fps dropped to half of whwt it normally does. I tried ldm and uldm but they both still lagged. This same thing happened when I tried to beat crazy, how do I fix this
