AMD Catalyst beta 14.1 Available:

AMD’s Catalyst 14. 1 Beta drivers were supposed to arrive on Thursday, at the same time while the Mantle patch for Battlefield 4. regrettably, things were delayed a bit, and AMD had to focus on the drivers to the weekend. On Friday evening, the drivers were released to the press, despite there still being some installation problems. The good news is these problems have been resolved and the drivers have been released for public consumption. It is possible to download them via AMD’s web site. Users must uninstall the existing driver before updating to Catalyst 14. 1.
Catalyst 14. 1 includes support for AMD’s new A10-7850K and A10-7700K APUs and is essential for users to see the benefits of the brand new Mantle API, which boosts performance in both Battlefield 4 and Star Swarm when running on R9 290 series cards. The Mantle beta driver is supported on AMD’s R9 and R7 series as well as its Radeon HD 7000 and 8000 series. AMD says Mantle performance for the Radeon HD 7000/8000 series and R9 280X and R9 270X GPUs is going to be optimized for Battlefield 4 in another Catalyst release.
