HardOCP had a chance to talk with ATI about their work with Microsoft on the upcoming DirectX 10, to be included with Windows Vista. DirectX 10 seeks to reduce the overhead from previous versions of DirectX, as well as increase flexibility to support future GPU. Assuming that Windows Vista makes its currently announced ship date, when DirectX 10 is available, it will have been about 4 years since DirectX 9.0 was released. In that time, users have seen many advancements to the pixel and vertex shaders common in all DirectX 9.0 GPU. DirectX 10 will bring access to a new geometry shader, and support for cards featuring a unified GPU architecture. The Xbox 360’s GPU already supports a unified architecture; this allows a more streamlined use of the features integrated into a GPU, and give the GPU the ability to take on more generalized tasks. Since Halo 2 for the PC will require Windows Vista and the improved DirectX 10, gamers may see a superior port of the game.
