BioShock Infinite is a first-person shooter where you assume the role of former Pinkerton agent Booker DeWitt, sent to the flying city of Columbia on a rescue mission. The game is using a modified version of the Unreal Engine 3 to improve lighting effects, rigid-body physics, cloth simulation, SSAO and audio processing. The game supports DX11 but only requires DX10 quality hardware to play. With a DX11 graphics card you are able to unlock advanced graphics features and take advantage of your hardware investment.
Bioshock is a fun benchmark and is something anyone can run if they have the Steam version of the game installed. it actually does quite well and will give you a CSV report on how the benchmark ran in every scene.
