well PhysX is NVidia thing [ was old AGEIA PhysX ]
physics is just that generic like in firestrike [3dmark] and is on the CPU as a cpu test
just try it both was and see what you end up with
see how NVidia confuses PhysX and physics ?

you know I'm going to see if I can test that to see for sure
ran firestrike and that new unigine superposition with aut0 select / gpu and cpu setting 3 runs each and did not see any benefit form any so I put it back to auto select ???
all scores stayed in there normal +/- of a few points
maybe if you had a NVidia physx optimized game it may be some help ???

the option actually exclusive to game that have GPU PhysX only. for games with GPU PhysX feature (like batman arkham series) if you put PhysX calculation to CPU everything will be done on CPU. including the portion that was supposed to be run on GPU. this can cause massive slow down. but if you put the option to GPU it doesn't mean every physics calculation in the game will be done by GPU. this is one of the misconception many people have with nvidia PhysX. most PhysX calculation is done by CPU. only minor portion of PhysX that use GPU.
