Sure, they haven’t made any of that.
But I am ragging on Nvidia for less than upstanding buisness practice.
Also, Nvidia really never made PhysX.
It was first NovodeX it was bought by Aegia. Nvidia bought Aegia out.

They really ruined it for everyone. (Also stopping any port of PhysX to AMD or competitors.)

Just putting the info out there.
Though I would suggest a 950 or 970 if you must have PhysX.
