"AMD has released a new build of their Catalyst software suite. This particular software suite updates both the AMD Display Driver, and the Catalyst Control Center. This unified driver has been further enhanced to provide the highest level of power, performance, and reliability. The AMD Catalyst software suite is the ultimate in performance and stability. Catalyst 11.1a Hotfix brings the following features:
AMD Radeon HD 6900 and AMD Radeon HD 6800 Series:
• 3DMark Vantage improves ~7%
• 3DMark06 improves ~3%
• Call of Duty Black Ops improves ~20% at 4xMSAA and up to 35% at 8xMSAA
• Riddick Assault on Dark Athena SSAO performance improves ~20%
• Unigine Heaven OpenGL performance improves ~10% at moderate, 30% at normal and 100% at extreme tessellation levels
AMD Radeon HD 6800 Series:
• Aliens vs. Predators improves ~9% at 2xMSAA and up to 20% at 4xMSAA
• Batman Arkham Asylum improves ~4%
• Crysis Warhead improves ~2-4%
• Metro 2033 improves ~28% at 4xMSAA
AMD Radeon HD 6900 Series:
• Battleforge DirectX 11 performance improves as much as 6%
AMD Optimized Tessellation
The Catalyst Control Center includes an early prototype of some new tessellation controls. Our goal is to give users full control over the tessellation levels used in applications. The default selection “AMD Optimized” setting allows AMD, on a per application basis, to set the best level of tessellation. The intention is to help users get the maximum visual benefit of Tessellation, while minimizing the impact on performance. Currently no applications have been profiled, so the “AMD Optimized” setting will be non-operational until further notice."
