If you're interested to know how ATI are doing in regards to preperations for Windows Vista, they've just released a document that describes their Vista graphics driver support in detail and how it differs to what we're used to today (with Windows XP etc.). Of course its all still work in progress but the white paper gives you a solid understanding of the benefits to be had once it all comes together in line with the big Vista release (now slated for launch early next year unfortunately).
