I also found the following:
Civilization 5 uses DirectX 11 and DirectCompute to leverage a variable bit rate texture codec algorithm. The algorithm is so efficient that 2 GB of leader textures compress down to less than 150 MB of disk storage.
DiRT 3 employs DirectCompute for its high-definition ambient occlusion (HDAO) effect. Unfortunately, there is no equivalent effect in the game based on pixel shading, so we can’t compare the two directly.
The advanced depth of field (DOF) effect in Metro 2033 needs three rendering passes. Two of these employ pixel shading, while the third uses DirectCompute."
