AMD has slipped out February's graphics card update a little earlier than usual. Catalyst 11.2 brings a few bug fixes and performance enhancements, but it seems to be largely focused on adding new features including finalized tessellation controls, which first appeared in last month's 11.1a hotfix.

Desktop: Windows XP 32-bit | Windows XP 64-bit | Windows Vista/7 32-bit | Windows Vista/7 64-bit
Mobile: Windows Vista/7 32-bit | Windows Vista/7 64-bit

The new tessellation controls give Radeon HD 5000 and 6000 owners the ability to manually tweak the tessellation level used by specific applications. The HD 5000 series has received morphological anti-aliasing, while the 6000 series can now adjust video quality during Blu-ray 3D playback.

There are also Catalyst AI Filtering updates, including a new method to improve filtering performance without affecting image quality. Over a dozen bugs have been address across Windows 7 and XP, with two causing display corruption issues in HAWX when running in DX9 and Lost Planet in DX10.

Meanwhile, folks running a single Radeon HD 5000 series graphics card can expect a boost of up to 11% in Call of Duty: Black Ops and 4% in Batman Arkham Asylum with anisotropic filtering and anti-aliasing enabled for the former and disabled for the latter. You can read the full release notes here.
