Up until today, the game was running fine, constant 30-40 FPS (easily and happily playable - I have a GT 540 M and an i3 2.53 Dual core with 4GB Ram).
Then for some reason, I sit down to play some more, and the game will only run at 7 FPS IF I'M LUCKY. GPU/CPU usage IS NOT maxing out (GPU hovering around 20-40% and CPU hovering around 70-80%), Disk usage is normal, nothing out of the ordinary. I have no clue what happened. I haven't changed anything at all as far as I know.
Any ideas before I completely delete everything? (probably going to reformat just because indows gets absurdly slower and slower over a few months)
