According to Andrew Dodd's recent Twitter activity, AMD will most likely release the Catalyst 13.2 beta driver at some point during next week. Notes on the issues solved by the update are not yet available to the public.
If you want to try an unofficial version, Benchmark3D offers a modded driver of the 13.2 beta. This includes version 12.10-130101a-151427E-ATI of the driver, 9.14.10.0960 of Direct3D and 18.104.22.16815 of OpenGL.
The fixes mentioned in the changelog provided include the unlocking of Temporal AA, High Quality AF, Geometry Instancing, LOD option, Adaptive Anti-Aliasing Quality Slider (can be buggy), Test Custom Clocks and Auto-Tune options under OverDrive.
If you're not interested in modded drivers, Guru3D offers an unofficial version that should be closer to what AMD is expected to release. Its package includes the same version for the driver, Direct3D and OpenGL.
According to the release notes, this version of the Catalyst 13.2 beta offers AMD Radeon HD 5000, HD 6000 and HD 7000 Series graphics cards full support for WDDM 1.2 (an updated model driver developed by Microsoft in order to ensure smooth performance and compatibility with their new operating system).
Below are the download links to the drivers mentioned above.
