With reports of Mantle still being in a sort of half-baked state (stuttering, glitching, etc), we should probably assume DX11 performance for this build...
-------
In DX11 mode:....
Almighty Sofa's build will do ~35FPS minimums in BF4 MP.
Pucky's build will do ~35FPS minimums in BF4 MP.
Jeff Baffalo's build will do ~35FPS minimums in BF4 MP.
esco sid's build will do ~45FPS minimums in BF4 MP.
Gun Fin X's build will do ~25FPS minimums in BF4 MP.
Nice work fellas.
--------
The AMD driver/API software layers are a bottleneck in this game. The only CPU's that can maintain 60ish FPS minimums while running the AMD DX11 implementation in BF4 MP are flagship class stuff from Intel (i7 -4790), often requiring overclocking...
