Highlights of the ATI Catalyst™ 9.2 Windows release include:

* Fix for problems with DirectX and Radeon HD 3000 and HD 2000 Series AGP Graphics cards.

This release of ATI Catalyst™ provides full OpenGL™ 3.0 extension support. The following is a list of OpenGL™ 3.0 extensions added in Catalyst 9.1:

• ARB_framebuffer_object
• ARB_half_float_vertex
• ARB_texture_rg
• EXT_texture_array
• EXT_texture_integer
• EXT_transform_feedback
• NV_conditional_render
• WGL/GLX_create_context (for new 3.0 contexts)
• GLSL 1.3
• ARB_color_buffer_float
• ARB_vertex_array_object
• EXT_draw_buffers2

With our earlier R500 2D testing the Catalyst 8.12 driver had won in 17 of the 28 tests, but with the RV770 2D testing, the same Catalyst driver only scored first in 9 of the 28 tests. The remaining 19 tests had exhibited better performance using the experimental R600/700 support in the DRM and xf86-video-radeonhd driver code. However, this code is still experimental and living in branches of the main driver. Not all 2D EXA operations are being accelerated by the GPU yet, which accounts for some of these results. We will be back with more benchmarks as the 2D and 3D open-source support for the R600/700 support stabilizes. Lastly, there will be improved 2D performance once a proper memory manager (using a combination of GEM and TTM) is in place for the open-source ATI driver and the improvements from UXA acceleration work their way back into EXA in future X Server releases.

After installing ATI Catalyst driver release 8.12 for two or more ATI Radeon HD ™ 4850 graphics cards in a system with ATI CrossFireX™ technology, the system restarts and halts on a black screen. The black screen occurs prior to the loading of the desktop for the Windows Vista 64-bit or Windows Vista 32-bit operating systems. This issue ONLY occurs when two or more ATI Radeon HD 4850 graphic cards are installed in the system with ATI CrossFireX technology. One single ATI Radeon HD 4850 card will not encounter this issue.
