The interview with Rebellion's Senior Producer David Brickley explains the technical advantages Aliens vs. Predator will have on the PC. Besides several graphics features and DirectX 11 support the engine will also make use of all available cores of a processor for the physics calculations.
Brickley says: while AvP looks fantastic on Xbox 360 and PS3, it looks truly state-of-the-art on PC. Similarly effects such as shadows and full-screen passes like ambient occlusion are more complex and detailed on PC, adding that "The PC version of AvP is fully able to take advantage of the features of all the latest video cards and is optimized to make efficient use of multicore threading if your PC supports it.
Brickley: "We will also be one of the first games to really show off how good DirectX 11 games can look, with hardware tessellation of the Aliens using displacement mapping, and Shader Model 5.0 Compute Shaders for post-processing effects."
The game is a perfect example of the PC supremacy over consoles. Apart from the obvious (read: controls), when viewing the screenshots, the "next-gen" argument of modern consoles (read: graphics) clearly becomes "previous-gen". A graphics awesomeness of this kind is simply not possible on the consoles.
