I am also having this problem and the game running entirely too slow like in this thread:
http://social.biowar...-4879430-1.html
I've done everything from fresh install, to messing with the cpu affinity, turning a core off, and it's still unplayable.
I have an HP Pavilan
AMD Turion Dual Core Mobile M260 at 2.5 GHz
and ATI Radeon M880g with HD 4200
and running Window 7.
Any new ideas would greatly help.
