DiRT 2 - High Definition Ambient Occlusion - DirectX 11

View this scene using DirectX 9

High Definition Ambient Occlusion is a technique that adds shading to the scene where light finds it hard to reach. This technique is typically very expensive, requiring many depth buffer samples and resulting in frame rate drops. Using Compute Shader 5.0, part of DirectX 11, High Definition Ambient Occlusion results in much more realistic lighting and shadows.
