loaded mantel (14.1) on my 8350, 2x 7850 2g card. while in game (bf4) on the initial game the cpu and gpu are spikeing really bad. the game crashes and upon reload the gpu runs great. the cpu still spikes but way less then when i first get into the game. this has happened 2 nights in a row since installing 14.1.
also i've been getting a 2-3 second black screen, sound is still present, i just changed my hdmi cable to a dvi cable and no black screen issues. this has occurred with both 13.xx and 14.1 drivers. it occurs in game or just surfing the net.
all in all when the cpu is not spikeing i like the feel of mantle. amd you gotta tweak it more!
