PhysX calculations will run in software mode (I.e. on your CPU) if there is no dedicated hardware solution.
It makes a huge difference on older machines....if I disable PhysX on my 9600GT my poor 6 year old dual core can't handle large amounts of objects onscreen at once - star base tribbles are especially bad. With PhysX enable there is no slowdown whatsoever.
So yeah, STO unquestionably uses PhysX for certain objects. I for one would not look forward to a DX11 centric solution as I would have to drop some cash on new hardware.
That being said, PhysX is indeed dead/dying, for the excellent reasons already stated above, and good riddance, hardware agnostic solutions have always been preferable to proprietary optimizations.
edit: just tested, again in fleet star base pile of tribbles. GPU usage with PhysX enabled was 100%, CPU usage averaged 37% and FPS over 2 minutes of kicking tribbles averaged 46.2. Same situation, new instance to use same tribble pile, PhysX off, GPU averaged 65% usage,CPU locked at 100% with fans going nuts, average of 12.7 FPS over 2 minutes. If I set debris and all physics settings to min/off, the results between PhysX enabled and disabled show a negligible difference.
PhysX is a complete physics SDK, like HAVOK. It doesn't require nVidia hardware to run, but its a helluva lot faster with it.
