As this issue seems to have been resolved with new drivers I'll mark this thread as solved now.
Will this ever be fixed ? I think the only fix will be never buy AMD GPU again and switch over to Nvidia.
Game render in unplayable state after 15 -30 min when playing BF4 with Mantle using 2 x 7970 Crossfire.
First it fills up whole VRAM then it beginns to fill up my complete Systemmemory (16GB).
Had a little hope when the 14.9.1 and 14.9.2 Beta drivers came out. But nothing. Playxing with DX works but the game runs not so smooth. With Mantle i got stable 144 fps capped @ High settings. DX gives me the Audio Bug and unstable fps from 70-144.
Crossfire + mantle in BF4 is a no go, and it seems the have no motiovation to fix this. How poor this is.
I use AMD GPU since the First Radeons came out, but this will be for sure the last pieco of silicone i ever bought from them. Tired of being a third class Gamer only because the couldnt fix they stuff. Looking forward to the GTX980.
The only solution is back to windows 7. Works for me.
