AMD now offers a new beta release candidate version 14.7 driver for AMD/ATI graphics cards running under Windows (thanks DSOGaming). Though a release candidate, these are still in beta, so all warnings about protective clothing and avoiding open flames should still apply. Here's word on what's new:

• Includes all improvements found in the AMD Catalyst™ 14.6 RC driver
• AMD ​CrossFire™ and AMD Radeon™ Dual Graphics profile update for Plants vs. Zombies​​​
• Assassin's Creed IV - improved CrossFire scaling (3840x2160 High Settings) up to 93%
• Collaboration with AOC has identified non-standard display timings as the root cause of 60Hz SST flickering exhibited by the AOC U2868PQU panel on certain AMD Radeon™ graphics cards. A software workaround has been implemented in AMD Catalyst 14.7 RC driver to resolve the display timing issues with this display.
  • Users are further encouraged to obtain newer display firmware from AOC that will resolve flickering at its origin.
  • Users are additionally advised to utilize DisplayPort-certified cables to ensure the integrity of the DisplayPort data connection.​​​
