Physx Grayed Out

[Cloud_Runner]

I recently got a NVIDIA Geforce GTX 970 and I was pretty excited to get PhysX working on Warframe so I of course install the card and drivers and on GeForce Experience I optimized Warframe's settings and was very glad to see PhysX Turned on, but when I go in game, it's grayed out and not actually running. I restarted my computer and set the PhysX and in the control panel set PhysX to run off my card and it still doesn't work.

 

Note that I did try installing a previous driver for PhysX and it wouldn't let me because it said I have a more recent version. So, help?

Set yourself to DirectX 11 and 64-bit mode in the Warframe launcher. That should open up the setting for you.

It works for me on my older card but i have to set it everytime i start warframe.

Hi, My PhysX option is Greyed out as well so I am hoping to get it fixed.

 

Geforce GT 730 Palit (PhysX Supported)

4gb Ram

Intel i3-2100 CPU @ 3.10GHz

32 bit

 

Yes I can run Warframe fine on Max Graphics. I am wondering if it is because I use 32 bit? Thanks.

i posted this in general which was probly the wrong place but has anyone else noticed that if you pause the game while in windowed mode or alt tab from full screen mode physx particles etc stop working
