The new Mantle API has arrived for BF4, with quite a few other games waiting in the wings which will also take advantage of this DirectX competitor.  The results that [H]ard|OCP saw were not as impressive as what the marketing would have had you believe but it still offers an improvement over DirectX in some cases.  With high end hardware running at EyeFinity resolutions [H] did not see much improvement, the GTX 780 Ti took the performance crown.  However on a single monitor with a R9 290 or 280X they saw very significant performance increases which left both the GTX 780 and 770 lagging behind in performance.  Mantle will not yet allow mid range GPUs to act like high end cards but there is promise in this new API.

"AMD's Mantle API has been with us for just over a month now, and we have strapped a variety of video cards to the test bench to see what real world differences are being delivered to gamers within Battlefield 4. We will compare D3D11, Mantle, on various GPUs, looking at highest playable settings, frame times, and discuss our experiences."
