released an out-of-cycle hotfix for this month’s Catalyst 10.8 drivers. Amongst all the fixes are those which appear to be geared to helping the latest Radeon GPU run Windows Vista and 7, 32-bit and 64-bit editions.
The first fix applies to Radeon HD 4870 X2 and HD 4850 X2 users. Apparently the previous drivers had a glitch that meant the two cores weren’t being made use of in some games. This caused a significant performance drop.
The second update applies to all DirectX 10-enabled cards across the 3000, 4000 and 5000 series cards. Basically this makes things better for users of Ubisoft’s H.A.W.X. when anisotropic filtering is enabled through the Catalyst Control Center.
