AMD has officially released the new AMD Catalyst 13.9 driver, AMD's first logo certified driver for Windows 8.1 that includes WDDM 1.3 support for bunch of AMD products including Kabini, Richland, Trinity and Temash APUs, as well as AMD's Radeon HD 8000, 7000, 6000, and 5000 series graphcis cards.
Although it is AMD's first logo certified driver for Windows 8.1 it does not include support for AMD Crossfire Frame Pacing or the very latest Crossfire optimization nor the additional performance improvements and fixes found in the AMD Catalyst 13.10 Beta driver.
The new Catalyst 13.9 certified driver supports AMD Eyefinity, OpenCL, OpenGL, UVD, AMD Dual Graphics/AMD CrossFire Technology, AMD Overdrive, AMD Catalyst Control Center/Vision Engine Control Center and requires NET 4.5 support for the Catalyst 13.9 Catalyst Control Center.
In case you missed it earlier, the Catalyst 13.10 Beta driver on the other hand brings improved Crossfire profiles for Rome Total War 2, Saints Row 4, Metro Last Light as well as a number of frame pacing improvements in games like Tomb Raider, Metro Last Light, Sniper Elite, World of Warcraft, Max Payne 3 and Hitman Absolution. The Catalyst 13.10 Beta driver also resolves some issues seen with previous Catalyst drivers.
