AMD has unleashed their latest beta driver for AMD graphics card holders, full of lots of goodies.
It's good to see AMD stepping up with the bug-fixes which is no doubt thanks to SteamOS and Valve for pushing them to work on their drivers.
I still see all too often people bashing AMD's graphics drivers, so let us know how this one works out for you!
Many people where worried about some Steam Machines using AMD graphics, I was too, but considering they are applying direct fixes for SteamOS as detailed below I don't think we will have to worry too much.
It includes support for their new APU's as well as Xserver 1.15 support & Kernel 3.13 support.
