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 the highest quality settings with 4x AA and 16x AF. DirectX-11 features such as Screen Space Ambient Occlusion (SSAO) and tessellation have also been included, along with advanced shadows.

  • Aliens vs Predator
    • Extreme Settings: (Very High Quality, 4x AA, 16x AF, SSAO, Tessellation, Advanced Shadows)

Cost Analysis: Aliens vs Predator (1680x1050)

  • $200 Radeon HD 5830 1GB costs $8.66 per FPS
  • $180 GeForce GTX 460 768MB costs $6.55 per FPS
  • $270 Radeon HD 5850 1GB costs $9.12 per FPS
  • $300 GeForce GTX 470 1280MB costs $8.85 per FPS
  • $260 GeForce GTS 450 SLI costs $7.65 per FPS
  • $365 Radeon HD 5870 1GB costs $9.89 per FPS
  • $360 GeForce GTX 460 SLI costs $7.66 per FPS
  • Test Summary: Aliens vs Predator may use the well-known Asura game engine, but DirectX-11 extensions push the graphical demand on this game to levels eclipsed only by Mafia-II or Metro 2033 (and possibly equivalent to DX10 Crysis). With an unbiased appetite for raw DirectX-11 graphics performance, Aliens vs Predator accepts ATI and NVIDIA products as equal contenders. When high-strain SSAO is called into action, the pair of 1GB GeForce GTS 450's in SLI demonstrate how well Fermi is suited for DX11, coming within a few frames of the more expensive ATI Radeon HD 5870 while pulling ahead of the Radeon HD 5850 it shares at the price point. NVIDIA's GTX 460 enjoys a significant cost per FPS advantage, followed by the GTS 450 SLI set (which matched performance with the GTX 470 in Aliens vs Predator). A single GTS 450 produced 17.7 FPS with the Aliens vs Predator benchmark at 1680x1050, while a pair combined into SLI delivered 34.0 FPS. This amounts to 96% SLI efficiency.
