BioShock is the "genetically enhanced" first person shooter with RPG elements, that has a feel very reminiscent of System Shock 2 or Deus Ex. It uses a modified Unreal Engine 3.0 with heavy emphasis on enhanced water effects to the extent that Irrational Games actually hired a water programmer and water artist just for this game. Part horror flick, part sci-fi novel, BioShock is an experience that one won't soon forget. We gathered our testing results by measuring frame rates through FRAPS while performing the same set of actions in the opening corridors of Rapture at 1280x1024 and 1600x1200 with all graphical settings turned to High.
Eerily similar to our ET: Quake Wars results, Bioshock has the 8600 GTS and Sapphire's HD 3650 battling it out for the middle ground. Each card wins a round here, with a frame separating the two at either resolution. Unfortunately for Diamond, its card is again dead last. Behind by 5-6 frames per second at 1280x1024, the gap actually widens at 1600x1200 to 6-7 fps when we would have expected otherwise. The larger memory buffer should have helped here, but its slower DDR2 memory interface speed hampers any gains it might have had.
