So after reading lots of news this week it looks like the PC versions of video games are dropping the Havok physics engine in favor of Nvidia's physics engine and graphical effects.
Exclusive to PC only PlayStation 4 (PS4) and Xbox One won't have these graphical effects except for DirectX 11 (DX 11) and Tessellation.
