with this new patch i can run regularly with about 120fps and 2boxing at around 50fps each.

Intel(R) Core(TM)2 Duo CPU E6850 @ 3.00GHz
Win xp
NVIDIA GeForce 8600 GTS 512
2gigs of ram

idk what it is exactly cause i ran on the same comp 1-67 and the only problem that would occur one in awhile was when i tabbed it would make the wow i tabbed into extremely magnified.
