Performance Improvements
Enhancements to our driver's internal memory management bring significant benefits to 64MB and 128MB framebuffer configurations in Catalyst™ 5.7.
The resulting performance gains are most apparent in high resolution, everything on modes, when running applications that use a significant amount of graphics memory. Examples include:
* 5-15% gains in 3DMark05 on some products
* 20-60% gain in Far Cry Regulator across multiple settings
* 25-60% gains in Half-Life 2 at 1600x1200 4xAA 8xAF
* 40-60% gains in UT2004 at 1600x1200 6xAA 16xAF
* 50-100% improvement in Comanche4 at 1600x1200 6xAA 16xAF
* 50-200% gains in certain ShaderMark tests at high resolution
Note: The exact magnitude of these performance benefits will vary depending on the product configuration, clock speeds and available system memory. All of the changes noted are specific to 64MB and 128MB framebuffer configurations. Performance of 256MB and 512MB boards is already very good at these settings.
