AMD has released new, unsupported Catalyst beta drivers for their video cards this evening. The 14.11.1 drivers include support for Call of Duty: Advanced Warfare and Assassin's Creed Unity.

As noted, these are unsupported beta drivers, so if you're going to try them out, be aware that they may come with some undesired issues. You can tempt fate by heading on over to the AMD website for more information and download links.
