User Defined Component Video HDTV Modes:
The CATALYST 4.5 driver provided a new interface that allows users to define the optimized modes for their HDTV's. This allows for images to be properly centered on their HDTV. The interface allows users specify a mode through a test window. Once the user saves this information, it will be saved as a user defined preference. This feature was not available in 4.5 and is now enabled.
OpenGL Hardware Acceleration for ATI Rotation
OpenGL Hardware Acceleration for ATI Rotation Mode. This feature is supported across the current shipping ATI Desktop product line, and is supported under both Windows XP, and Windows 2000.
As with most CATALYST releases performance has increased in various situations. The following performance gains are noticed:
- Pixel Shader compiler improvements bring significant performance gains to PS 2.0 applications such as Halo (2-3%), Tomb Raider (4-5%) and Mother Nature (4-5%). ShaderMark 2 shows numerous gains in the 3-6% range. The High Dynamic Range scenes in ShaderMark (Tests 20 & 21) gain 10-15%.
- RADEON X800 driver tuning improves performance for several Vertex-Shader-heavy tests. For example, Battle of Proxycon, Troll's Lair and Mother Nature gain 9-15% on the RADEON X800 PRO.
- Improvements in our surface allocation and texture management code have increased performance for resource-challenged cases. Re-Volt scores improve 25% at 1600x1200 across several RADEON configurations. ShaderMark Test 14 (Veined Marble) improves dramatically (up 380% at 1600x1200) on some 256MB products.
- Improvements in OpenGL driver efficiency bring numerous small gains (1-3%) in Call of Duty, Wolfenstein - Enemy Territory, Star Trek - Elite Force II, Serious Sam, Return to Castle Wolfenstein and Quake III Arena.
- X800 memory tuning improves Anti-Aliasing performance in a number of games and benchmarks. For example, at 4xAA, 3DMark2001 gains 4-7%, UT2003 Antalus and Asbestos Flybys improve 2-7%, and the CodeCreatures score rises 15%.
