AMD has published the Catalyst 14.9.1 Beta driver, you can download it over here. This release is an emergency fix for some issues that arose with the Catalyst 14.9 driver. AMD claims these issues are isolated and recommends sticking with Catalyst 14.9 if you're not experiencing problems.
Due to a small number of isolated usability issues in last week's AMD Catalyst™ 14.9 driver that were reported by end users, we are providing an updated driver that addresses those usability issues. If you are not facing any problems we recommend you continue to use the latest AMD Catalyst™ 14.9 driver which is available at www.amd.com
