Codemasters have decided to delay the PC version of Colin McRae: Dirt 2 until December in order to take advantage of the features in DirectX 11.
"While the console editions of Colin McRae: DiRT 2 will retain their September ship date, we believe that the DirectX 11 feature set is too compelling to ignore, especially considering how much more it can add to the visual experience for PC gamers," said Bryan Marshall, chief technical officer, Codemasters. "As a leader in digital racing entertainment, we are staying ahead of the pack by immediately taking advantage of key new technologies such as hardware tessellation, multi-threading and Shader Model 5.0 to deliver the most realistic, immersive and exhilarating racing experiences in the business. The fusion of DirectX 11 with Codemasters' EGO Engine will raise the technical bar considerably in the racing genre."
