Got my new AMD HD 2600 Pro last weekend, and was finally able to play Bioshock. It's fucking awesome, and it sucks so hard, that I can't play stuff like this on my laptop. Still, Irrational Games can suck my dick for making the game only for cards supporting SM 3.0 and up.
It's the Unreal 3 engine, not Irrational (now 2K Boston/Canberra) - mod
