BioShock 2 is out, to those that have purchased it, how does it perform? If you could include your system specs and games settings with your post, that would be awesome! Also, it's disappointing that ATI HD2xxx series are unsupported. To anyone who has an iMac 7,1 or an ATI Radeon HD 2600 Pro 256 MB and bought the game, does the game launch at all? If so, how is the performance? It's not a bad GPU compared to the intel 3000 and the nVidia 320m. This game has a strange requirement cut off point. Thanks in advance everybody!
