Catalyst 11.12 Windows 7 Driver Analysis


It's been a fairly quite year for the Catalyst driver set so far and while AMD have indeed been busy with the latest crop of Radeon HD 7000 series video cards that we started seeing in December, there hasn't been much on the software side of things that really stands out.


Looking through the latest release notes it feels very much the same with not much in terms of specific performance improvements outside of some Morphological Anti-Aliasing tweaks that are seeing a strong boost. If that translates over to the more traditional AA method we won't know until a little later.


Outside of that, though, there's a huge amount of bug fixes in some popular games and applications which will no doubt be the thing that drags you to the latest driver.



Release Notes Highlights




Windows XP support for the AMD Radeon HD 7900 Series, AMD Radeon HD 7800, and AMD Radeon HD 7700 Series


In addition to Windows 7 and Windows Vista support, Catalyst 12.4 now also introduces Windows XP (64-bit/32-bit) support for the AMD Radeon HD 7900, AMD Radeon HD 7800, and AMD Radeon HD 7700 Series


Super Sampling Anti-Aliasing: Level of Detail (LOD) Image Quality enhancements


Supported on the AMD Radeon HD 7900, AMD Radeon HD 7800, and AMD Radeon HD 7700 Series

LOD Image quality enhancements have been improved when enabling Super Sample Anti-Aliasing and Adaptive Anti-Aliasing through the AMD Catalyst™ Control Center for DirectX 10 and DirectX 11 applications.

Applications must support in game Anti-Aliasing for the feature to work (Forced on Anti-Aliasing through the Catalyst Control Center is not supported for DirectX 10 and DirectX 11 applications)


Morphological Anti-Aliasing (MLAA): Significant performance enhancements


Supported on the AMD Radeon HD 7900, AMD Radeon HD 7800, AMD Radeon HD 7700 Series, AMD Radeon HD 6000 Series, and AMD Radeon HD 5000 Series

MLAA now operates up to 80% faster than previous versions


Texture filtering quality improvements


Supported on the AMD Radeon HD 7900, AMD Radeon HD 7800, and AMD Radeon HD 7700 Series

Improvements have been made to the texture filtering algorithm (for both DirectX9 and DirectX10/DirectX11 applications) to increase the quality of rendered textures, with no impact to performance
