AMD releases Catalyst 7.3 graphics drivers


— 1:49 PM on March 28, 2007

A new Catalyst 7.3 graphics driver for AMD's line of ATI Radeon graphics card is now out. The driver is available for Windows XP, Windows Vista x86, and Windows Vista x64.

AMD says the Vista versions of the drivers bring OpenGL support as well as other enhancements to Radeon X1000-series CrossFire configurations. Namely, the drivers enable the Alternate Frame Rendering CrossFire mode by default, which improves performance for AFR-compatible apps that aren't officially profiled by AMD's multi-GPU technology. AMD claims the new drivers offer performance gains of at least 12.5% for all Radeon X1000 CrossFire setups in Dark Messiah of Might & Magic, as well, although those gains apply to both Vista and XP. AMD's high-end cards reportedly see gains of 60% or more in the game.

On the bug fixes front, AMD says the Vista versions of the drivers fix bugs in 3DMark 2006, Call of Duty, Call of Duty: United Offensive, City of Heroes, Doom 3, NBA Live 07, Neverwinter Nights, and Neverwinter Nights: Shadow of the Undrentide. No major game fixes are listed for the Windows XP release. However, a complete list of bug fixes and changes for both XP and Vista versions of the drivers is available here.
