I've got a A10-7850k in dual graphics with an XFX R7 250 2GB ddr3 and 8gb ram 2400.
I'm playing battlefield 4 in medium settings with directx and I can see the dual graphics logo and I get 45 to 55 fps.
I enable mantle without touching any other settings and I get 30-33 fps witch is the same as before I installed the XFX and I don't get the dual graphics logo. Can anyone confirm if mantle is working in dual graphics with my setup? Am I doing something wrong?
