Hi,  please help.
Hardware acceleration(GPU) on MAssFX toolbar dont work !
spec
Win 10 x64
3dsmax 2016 sp4
GPU - GTX 960  4gb

I open  Nvidia sample scene  press simulate, and its  simulate on CPU  NOT GPU !     (Hardware acceleration i turned ON)

I update   Latest GPU drivers, update PhysX Toolbar (3.4)   and try again -  nothing ! Again simulate on CPU !

I go in office  and try on different machines with diferent GPU   and max 2014  2016  2017  - NO GPU acceleration   all my pc  simulate  on CPU only !

I don't think PhysX is still alive... At least it doesn't interest Nvidia at all anymore.

Does not help any, but I currently use PhysX4 in my max-plugins - installed in parallel with the old 3dsmax PhysX version. The switch from V3 to V4 was more or less simple. PhysX5 is now open source - but I never tested.

well, making something open source is hardly killing it.
PhysX seems to do quite well within Omniverse.

So do I assume this is still a bug or there is more to the story?
