Are the Devs aware of the unlocked core for PS4? And will they use it?

It's been said many times, but the PS4 doesn't utilize DX11 nor could it as it's a Microsoft "product". The PS4 has its own low-level API which is more efficient than DX11.

The PS4 may not utilize DirectX, but the primary engine developed by SE does for portability reasons. Otherwise you'd see much wider gaps between PS4 and PC effects and performance.
