if PS4 is the lowest common denominator, and we all know it will, that in its own right might hinder the graphics for PC users, as we all don't want just ps4 port, i mean for some people ps4 will look same as pc, and lets hope there is noticeable differences , and some better cpu utilization implementations , but if there is no difference to ps4 version and PC dx11 version, then its clear what they chosen to do, and that once again il have mod the hell out of graphics to push it even further through 3rd party software and drivers, now what would stop them for pushing what graphics are like for MMO's, if they scale correctly, and use AMD mantle, sucks for Nivida users , then should even see more implementations for better graphics instead of use of DX11 API, as DX11 APi is bottleneck to what GPU's and CPU can do, as it most people should know DX11 is not great, future is mantle , metal on metal performance . well closer then anything MS has with DX11
Mantle is a low-level API specification[2] developed by AMD as an alternative to Direct3D and OpenGL. Currently the only implementation is for AMD's GCN graphics processing unit architecture
Up to 9 times more draw calls per second than comparable APIs by reducing CPU overhead.[3]
More fine control over the hardware.[3]
All hardware capabilities are exposed through the API.[3]
New rendering techniques possible.
Direct GPU memory access.
Prevents CPU bottlenecks.
Multithreaded parallel CPU rendering support for at least 8 cores.[4]
No game developer reliance on existing AMD driver support release schedules. (potentially no or less bugs on release, much faster patching for GFX related errors)
Due to bypassing of error-prone and inefficient abstraction, common technical difficulties like FPS drops, micro stuttering and texture corruption may be significantly less frequent or nonexistent.
Substantial performance increase compared to high-level APIs such as DirectX and OpenGL
