Driver Update: AMD Catalyst 15.5 Beta

AMD has released a new beta Catalyst driver. The driver is only suitable for Windows 7 and Windows 8.1, with a separate download for 32bit and 64bit environments. Support for Windows 8.0 has been discontinued with version 14.6 and AMD therefore recommends installing the free update to Windows 8.1. The new driver includes optimizations for the games The Witcher 3: Wild Hunt and Project Cars. While some improvements have been made, not all issues with these games have been resolved yet.

Know Issues:

• The Witcher 3 – Wild Hunt: To enable the best performance and experience in Crossfire, users must disable Anti-Aliasing from the games video-post processing options. Some random flickering may occur when using Crossfire. If the issue is affecting the game experience, as a work around we suggest disabling Crossfire while we continue to work with CD Projekt Red to resolve this issue
• [419945] Project CARS: Corruption may be observed if Anti-Aliasing is set to DS2M when run in Crossfire mode. As a workaround we suggest using a different Anti-Aliasing method.
