AMD now offers a new Catalyst version 14.9.2 Windows beta driver for AMD/ATI graphics cards, indicating this is recommended to play Sid Meier's Civilization: Beyond Earth, the just-released strategy sequel (thanks AnandTech). Word is: "This driver enables AMD Radeon™ GPUs with the Graphics Core Next architecture to take advantage of the ultra-efficient Mantle API support featured in Sid Meier's Civilization®: Beyond Earth™!" That said, this is still a beta, and are explicitly offered "as is."
