Physx Won't Work Now

[Pransaculass]

So I have a GeForce GT 640 and it USED to be able to run Warframe near max settings (all aside from anti aliasing and local reflections) with Phys X and still keep at around 30 FPS give or take (excluding cluster bombs of enemies). It can still run it near max settings, but now all of a sudden the Phys X option is greyed out and wont work any more.

 

I have:

- All the latest drivers and NVIDIA updates

- Made sure in the control panel that Phys X is turned on

- Done just about everything else that the internet has told me to do.

- Even checked the NVIDIA Path in Environment Variables.

 

I seriously don't know what's wrong here. If anyone could enlighten me as to the current Phys X situation that would be lovely.

 

Thanks

It is working fine for me, so the issue is most likely on your end. You seem to have already tried everything that I would recommend though.

Had the same problem not long ago. Try to uninstall physX and install the version from nvidia site. Even if you already have the lastest version.
