Dalla redazione di HWUpgrade, apprendiamo che AMD ha reso disponibile al download i driver Catalyst versione 12.4, che introducono il supporto alle schede video Radeon HD 7900, 7800 e 7700 con il sistema operativo Windows XP in versioni a 32bit e a 64bit; inizialmente abbinate ai soli sistemi Windows Vista e Windows 7.
Introdotte nvità anche a livello di qualità del filtraggio delle textures, del Super Sampling Anti Aliasing e del Morpholofical Anti Aliasing. Per essere più precisi di seguito vi riportiamo il changelog ufficiale:
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 for 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
Resolved issues: Highlights of the AMD Catalyst 12.4 driver:
- Elder Scolls: Skyrim : flickering square corruption is no longer observed on certain AMD Graphics cards.
- Rage : Vsync is no longer disabled after task switching.
- Tearing is no longer observed on the third screen in 3×1 and 1×3 Eyefinity configurations.
