i just played Max Payne 2 on my ATI A3, big jerky on the screens full of fog. but i had settings on high-ish and only probs was on big foggy screens.
Vice City is flawless, so is Mafia. HomeWorld 2 moans about incompatible graphic card but runs like a dream.
Old ATI still is a million times better than any Voodoo :-D IMO
