AMD has posted a new Catalyst driver here for id Software's Rage. Here's the scoop.

Significant performance gains for single GPU configurations
Compatible with AMD Radeon™ 6000 and AMD Radeon 5000 series of graphics products
Includes the latest OpenGL driver component for Rage performance optimizations

AMD have released Catalyst 11.9 drivers today. This is after releasing a beta of 11.10 for Battlefield 3.

AMD have released a preview version of the Catalyst 11.10 drivers for Battlefield 3 with specific performance improvements.

AMD has released Catalyst 11.8 drivers. Here are some details.

AMD Overdrive has been enhanced to include both CPU and GPU over-clocking controls within the AMD Vision Control Center
CPU over-clocking is only supported on AMD Black edition CPUs

Performance highlights

Improves performance up to 10% in Crysis 2 DirectX 11 version for both non-Anti-Aliasing, and application enabled Anti-Aliasing cases on the AMD Radeon™ HD 6000 and AMD Radeon™ HD 5000 Series
Improves performance up to 8% in Fear 3 DirectX 11 version with application enabled Anti-Aliasing on the
AMD Radeon™ HD 6000 and AMD Radeon™ HD 5000 Series
Improves performance up to 30% when AMD’s Morphological Anti-Aliasing (MLAA) is enabled through the
Catalyst™ Control Center on the AMD Radeon™ HD 6000 and AMD Radeon™ HD 5000 Series
Improves performance up to 20% in Call of Duty Black Operations for single GPU and Multi-GPU configurations on the AMD Radeon™ HD 6000 and AMD Radeon™ HD 5000 Series​​

AMD blogs about AMD releasing Catalyst Beta drivers for OpenGL 4.2.

Increased support for advanced techniques like single-rendering-pass order-independent transparency with the ability to enable shaders with atomic counters and load/store/atomic read-modify-write operations to a single level of a texture. This can make it easier for developers to efficiently manage which objects are visible without requiring multiple rendering passes

The ability to save cycles by capturing GPU-tessellated geometry and drawing multiple instances of the result – this means that complex objects can be efficiently replicated and repositioned

A new feature to allow modification of an arbitrary subset of a compressed texture, without having to download the texture to the GPU again, which can enable significant performance improvements

A full set of shader language features, including support for packing 8- and 16-bit values into a single 32-bit value for efficient shader processing with significantly reduced memory storage and bandwidth.

You can download them here for Windows and here for Linux.
