Yesterday, AMD debuted the Catalyst 8.4 video driver for Radeon 9500, X1800, and X1900 series video cards, as well as all HD 2000 and HD 3000 series cards. The driver release is primarily aimed at fixing bugs in a number of popular games - Hellgate: London, Crysis, Company of Heroes, and Doom 3 to name a few - and also includes support for the new HD 3850x2 enthusiast display solution. It has also been reported in our Discussion Forums that the 8.4 Cats may help enable Crossfire in systems that historically have had trouble with the double GPU solution. You can get the Catalyst 8.4 driver here for all flavors of Windows XP and Vista.
