If you're lucky enough to own a Radeon HD 2900XT based graphics card already, you'll be glad to know ATI have pumped out their latest official 7.5 driver suite today which brings full DirectX 10 support in conjunction with Vista.

There was a beta driver out upon the card's release which did the same thing, though this official release deals with bugs and issues whilst improving overall performance.

There's also mention of a BIG OpenGL performance increase in Vista as well, not to mention the usual array of bug fixes for various game titles in both XP and Vista.

For the full changelog you can get to the release notes here, and download the drivers here.
