A new ATI Catalyst 10.9 Hotfix is now available for Windows 7/Windows Vista, supplanting the just-released AMD/ATI reference drivers mentioned in the story below. Here's word on what the hotfix addresses: "ATI Radeon™ HD 4870 X2 and ATI Radeon HD 4850 X2 series of products use both Graphics Processing Units (GPU) for high performance." If this sounds familiar, that's because these are the same changes in last month's 10.8b hotfix. This may not be an oversight as much as a support issue, since the hotfix is an "as is" release, as AMD explains: "This hotfix is provided as is and is not supported by AMD. It has not completed full AMD testing and is only a driver update." Thanks Ant via Rage3D.
