DX11: Aliens vs. Predator

Aliens vs. Predator is a science fiction first-person shooter video game, developed by Rebellion, and published by Sega for Microsoft Windows, Sony PlayStation 3, and Microsoft Xbox 360. Aliens vs. Predator utilizes Rebellion's proprietary Asura game engine, which had previously found its way into Call of Duty: World at War and Rogue Warrior. The self-contained benchmark tool is used for our DirectX-11 tests, which push the Asura game engine to its limit.

In our benchmark tests, Aliens vs. Predator was configured to use high quality settings with 4x AA and 16x AF, along with tessellation, advanced shadows, and Screen Space Ambient Occlusion (SSAO).

This is a fairly tough test, tougher even than Crysis Warhead, judging from the frame rates. Of course Warhead, being a DX10 game, doesn't have tessellation or SSAO. The HD6950 continue to dominate here, with even the non-overclocked configuration beating the scores of the GTX570.
