Judging by the Driver Packaging Version and the increased OpenGL version (in-comparison to the OGL 4.3 Beta Drivers), I'd say these fix an issue in RAGE
Working on a 7850 on 8.1 RTM
Working Switchable Graphics on 7660G + 7670M on 8.1 RTM
WDDM 1.3 and DX11.1 Compatible (on supported hardware and platform)
Driver package only contains Display and WDM (HDMI) Drivers (no amdkmpfd or anything else)
Driver seems basically the same as the OpenGL 4.3 Beta Driver, with an updated OpenGL version
