Heads up all you Radeon HD graphics card owners, AMD has released a new batch of WHQL certified Catalyst drivers, version 13.9. These are the first logo certified drivers for Windows 8.1, which Microsoft is planning to make available to download on October 18th (free for existing Windows 8 owners, $120 and up for the full retail version). Catalyst 13.9 supports both 32-bit and 64-bit flavors of Windows 7, Windows 8, and Windows 8.1. Here's what else you need to know.
According to the Release Notes, Catalyst 13.9 does not include support for Frame Pacing or the very latest AMD CrossFire optimizations. If either or both of those are deal killers, you can opt instead to download and install a beta version of Catalyst 13.10, just be advised that stability or other odd issues may arise from playing around with pre-release code.
Catalyst 13.9 includes WDDM 1.3 support for a whole bunch of Accelerated Processing Units (APUs), along with Radeon HD 5000 through 8000 Series graphics cards. It also adds OpenGL support for User Profiles and Catalyst Application Profiles, and includes enhancements to AMD's Enduro technology (Catalyst Control Center now shows which applicatons are active on the Performance GPU and Power saving GPU).
In addition to the above, Catalyst 13.9 resolves a handful of issues, including what AMD describes as "severe flicker" in Far Cry 3 game cinematic that could spill over into gameplay.
