Results: Bioshock Infinite
Bioshock Infinite adds all kinds of fancy tricks to the PC to make visuals that are, hyperbole aside, simply stunning. Or at least new. It is based on UE 3.0, but still has plenty of bells and whistles to make things look really nice with many interesting effects. Ultra/DX11/DOF is enabled while using the built-in benchmark.
NVIDIA performs pretty good here, easily outpacing the 270X while closing in on the 280X.
