I'm having an odd issue with Windows 7 and my HD 4850 Graphics Card. It seems that when I a fresh install the graphics work fine, but I do notice that the driver is using the WDDM Version. When I decide to use the updated version from website I get this blurry picture. It almost looks like something is attempting to smooth the actually videos on the screen. Also, my 720p movies look atrocious. Regardless it looks horrible either way I look at it. When I use XP x64 and the same drivers (Made for All Versions) it works fine and performs remarkably. I'm in no rush for Windows 7, but I can't seem to figure out what could be the cause of the picture quality to go down when I use the manufacture's drivers.
