didn't crash for me
DX less than 1 FPS
even though i'm using my sister's computer which has a weak processor
my computer has a Intel i7 Extreme Edition 4 GHz 6-Core
and for the record, having alot of cores don't really make a difference because TPT hogs 1 core for it self.
so you only need a processor with 2 powerful cores, if you don't run alot of background programs.
My sisters computer is an AMD Athlon II Dual-Core M300 2.00 GHz
