Should the Witcher 3 support GPU PhysX? Probably not...

[Eruvadhor]

If the game is GPU and not CPU bottle-necked, then CPU physx makes more sense.

Well. i just hope that we can manually force this kind of PhysX to run on a secondary GPU, instead of CPU (just like i did in Lords of the Fallen)

The all-platforms physics computations are done on CPU. That makes sense... doesn't preclude there being additional elements of VisualFx producing visual effects only that optionally run on GPU.

We do know that APEX destruction and cloth are CPU base, but Hairworks is GPU tessellation.
