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.

New features introduced in this release of Catalyst includes OpenGL CrossFire support under Windows Vista. Catalyst 7.3 introduces OpenGL CrossFire support for the entire ATI Radeon X1000 product series. In addition, Catalyst 7.3 includes CrossFire enhancements for Windows Vista that enable the Alternate Frame Rendering (AFR) CrossFire rendering mode by default, enabling performance benefits for all AFR compatible applications immediately.

AMD promises that Dark Messiah Might and Magic performance improves 12.5% or greater on all Radeon X1000 series configurations when running in CrossFire mode under both the Windows XP and Windows Vista operating systems. Larger gains of 60% or more can be seen on high end products.

A complete list of bug fixes and changes for both XP and Vista versions of the drivers is available here.
