Performance Improvements
As with most CATALYST™ releases, the performance has increased in numerous situations. Here are some examples observed in CATALYST™ version 3.7. These include:
Pixel Shader processing has been enhanced across all of our DX9 products. As a result, certain PS 2.0 ShaderMark tests are now running as much as 12% faster.
Unreal Tournament 2003 performance is up considerably for DX9 products running with Anti-Aliasing enabled. This is due to improvements in the driver code for rendering character shadows. For example, the Anubis botmatch test gains as much as 23%
--------------------------------------------------------------------------------
Note: The UT2003 FlyBy tests do not contain any characters, and therefore will not show this effect. Real game play, however, will certainly benefit.

The result of this optimization is also apparent in Dungeon Siege, where gains ranging from 3-10% are observed on our DX9 product line-up, when Anti-Aliasing is enabled. Other game titles may also be improved
RADEON 7000 gains as much as 25% in Direct3D titles when running at very high resolution (1600x1200). Aquamark, Comanche 4, Dungeon Siege, Expendable, Giants and Re-Volt all gain approximately 20% at this setting. OpenGL titles are not affected
Modest gains of approximately 5% are noticed for our DX8 class of products (RADEON™ 9200, 9000, and 8500) in OpenGL games such as Quake III Arena, Return to Castle Wolfenstein, and Serious Sam
