Aliens vs. Predator (AvP) is an FPS title from Rebellion Studios. It allows players to take on the role of either an Alien, a Predator or a human space marine. While the title received mixed reviews, it is a DX11 graphics powerhouse that can bring many machines to their knees.
The demo follows a number of Alien creatures, and makes extensive use of shaders and tessellation. Hitting 60fps in Eyefinity is not possible on a stock Core i7-920 (at max settings), even with a pair of AMD Radeon HD 6970's in CFX. Dropping to 3x1600x900 produces a noticeable increase in fps.
