Codemasters announces the Games For Windows LIVE edition of Colin McRae: DiRT 2 is delayed until December 2009, explaining the game will support DirectX 11 out of the box. Word is:

With the introduction of Microsoft Windows 7, DirectX 11 will be made available both as part of the operating system and as a downloadable update to Windows Vista. Codemasters intends to immediately take advantage of DirectX 11 features that add to the realism of the racing environment. Hardware tessellation will further improve the appearance of water and other surfaces as well as crowd animations.

The shader performance of Shader Model 5.0 (SM 5.0) will aid in creating an even richer 3D experience, enhancing key image quality parameters such as depth of field, ambient occlusion and shadows. These DirectX 11 features, and many others, will add the horsepower needed to improve performance.
