Release Notes


If you would like to read the full release notes, they can be found here at the ATI website.


Performance Improvements


As with most CATALYST™ releases performance has increased in various situations. The following performance gains are noticed:


Direct3D driver efficiency has improved considerably. Significant performance gains are noted in multiple "CPU-bound" cases, including 3DMark2001, Aquamark 3, Comanche4, Dungeon Siege, and Unreal Tournament 2003 and 2004. Typical improvements are in the 1-5% range.


OpenGL driver efficiency is also improved. Older OpenGL games such as Quake III Arena and Wolfenstein - Enemy Territory show small improvement (1-2%) at low resolutions. Call of Duty framerates are up approximately 4%. Doom3 improves considerably more (as much as 12% on some product configurations) as a result of the same software efficiency improvements.


ATI are currently working quite hard it would seem on their OpenGL optimization as they have seemed to receive quite a bit of bad feedback regarding results in Doom 3. We have just added Doom 3 into our benchmarks and we will see what kind of performance jump if any we get with the new drivers.
