Codemasters announces the unveiling of the DirectX 11 edition of Colin McRae: DiRT 2 at a Windows 7 launch event. In July it was announced that the PC edition of the racing sequel was being held back until December to implement DirectX 11 support, and this announcement offers specifics, saying the PC edition is coming on December 1 in North America, December 3 in EPAC territories, and December 4 in the UK. Here are some new screenshots, there's a Direct X 11 DiRT trailer on ActionTrip, FileFront, and Gamer's Hell, and here's a bit on DirectX 11 support: "Codemasters will take advantage of DirectX 11 features to 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 performance of Shader Model 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, combine to deliver the most exciting and visceral racing experience yet."
