In an interview with PCGamer, BioShock Infinite technical director Christopher Kline outlined the extra features gamers with DirectX 11 would be getting.

“First, there’s Contact Hardening Shadows that take advantage of DX11′s Shader Model 5. These look much more realistic than the shadows available on DX10 hardware.

“Next up, AMD’s High Definition Ambient Occlusion (HDAO) takes advantage of DirectCompute to add extremely high-quality micro-detail to indirect shadowing in the scene, which greatly increases visual fidelity," said Kline.

“We also provide an alternate post-processing mode that uses Compute Shaders to implement Diffusion Depth of Field, creating a softer and more photographic look to portions of the scene that aren’t in focus. And finally, our implementation of FXAA has a special version optimized specifically for SM5.”

The game’s expansive outdoor environments were a particular challenge for Irrational, said Kline.

“Right from the beginning our rendering team was faced with the problem of supporting BioShock Infinite’s much wider range of environments.

“To do this they had to implement a new renderer with entirely different approaches to lighting, shadowing, and level of detail," he said.

“The resulting technology is a powerhouse that can handle not only the hugely expansive and brightly lit outdoor areas of Columbia, a floating city where everything is constantly moving, but also dark and creepy interiors similar to those in the original BioShock.

“Supporting these extremes well, and increasing visual quality at the same time, was an enormous challenge.”

BioShock Infinite is due out on Windows PC, Xbox 360, and PlayStation 3 on March 26.
