If you are an AMD graphics card user there is an updated driver available for you today with the release of Catalyst 9.12.  There aren’t a lot of performance changes in this driver (only 3DMark Vantage and STALKER: Call of Pripyat are noted) but there are some nice feature additions:

ATI Catalyst support for DirectCompute 10.1 
This release of ATI Catalyst provides full support for DirectCompute 10.1 for the ATI Radeon HD 4800 Series, ATI Radeon HD 4700 Series for both single card and ATI CrossFireX supported configurations.

OpenGL 3.2 extension support
This release of ATI Catalyst provides support for OpenGL 3.2 extension support on the ATI Radeon HD 5800 Series, ATI Radeon HD 5700 Series, ATI Radeon HD 4000 Series, ATI Radeon HD 3000 Series and ATI Radeon HD 2000 Series.    The following is a list of OpenGL 3.2 features and extensions added in ATI Catalyst 9.12:
Support for OpenGL Shading Language 1.50.
BGRA vertex component ordering (GL_ARB_vertex_array_bgra).
Drawing commands allowing modification of the base vertex index (GL_ARB_draw_elements_base_vertex).
Shader fragment coordinate convention control (GL_ARB_fragment_coord_conventions).
Provoking vertex control (GL_ARB_provoking_vertex).
Seamless cube map filtering (GL_ARB_seamless_cube_map).
Multisampled textures and texture samplers for specific sample locations (GL_ARB_texture_multisample).
Fragment depth clamping (GL_ARB_depth_clamp).
Geometry shaders (GL_ARB_geometry_shader4).
Fence sync objects (GL_ARB_sync).

Interestingly, there is going to be a hotfix 9.12 driver that includes some last minute additions that the AMD crew didn’t get in before sending it off for Windows certification.  More than likely, readers of PC Perspective are going to comfortable with this release available here.  This driver is the first to bring Eyefinity support to CrossFire configurations using not only the Radeon HD 5970 but the HD 5800 series and 5700 series as well!  Just in time for the holidays…
