ATI Catalyst 10.5 WHQL Driver Suite Released

As far as I can see, no changes for any of the HWBOT benchmark suite in terms of performance.

AMD today rolled out this month's release of its ATI Catalyst software, which provides drivers and essential system software for ATI Radeon graphics processors, AMD chipsets, and other ATI multimedia products. The WHQL-signed version 10.5 brings a few feature updates, along with a list of important bug fixes. To begin with, Catalyst 10.5 gives 120 Hz display support for ATI Radeon HD 4000 and HD 3000 series graphics processors (helpful with stereoscopic 3D), and ATI Overdrive enhancements which allow full control over ATI Radeon GPUs that are connected to multiple displays, eliminating a limitation. Following on with Catalyst 10.4, Battlefield: Bad Company 2 doesn't take unusually long to load maps, while a stability issues connected to IL-2 Sturmovik: 1946, Mass Effect 2 (where display goes blank if you switch to desktop in the middle of a game), Empire: Total War, Napoleon: Total War got a fix which allows AA settings with Volumetric effects, while Unigine Heaven 2.0 in wireframe mode doesn't crash.
