I don't know if I just failed at getting the proper drivers or something, but I couldn't even run Half Life 1 based games (CS, TFC)smoothly on bootcamp. I've run the mac OS version of call of duty 4, which runs... ok. Given that it runs CoD 4 alright I'm positive it has the ability to run HL or HL2 fine I just never really got it to jibe with windows. Maybe I should have updated opengl? either way I don't have windows on anymore to tweak it. I really can't think of any use for windows to me other than games, which I usually play on my xbox.
