NVIDIA Physx not working

[GONY100]

So after U18.5 , my Physx effects were turned off. I had the problem long ago but fixed it by changing some of the settings, but now I forgot what options to turn on/off so ill be able to turn nvidia physx on again.

If you know how to turn them back on, please tell me down here. It will be appreciated.

I thought I read somewhere that the driver/version requirements increased.  What video card, what driver version?

You did already go into options and display settings? 

Otherwise you may want to find your old ticket (if you asked support before) to find the solution there. If not, and there is no genius in the community I think contacting support is the best

Since the 18.5 update many people have been unable to get Warframe PhysX working properly.

A few have got it working by setting PhysX to CPU in the Nvidia Control Panel, but for most this just re-enables the PhysX toggle in Warframe while leaving the actual PhysX effects disabled.
