Physx Not Working With Latest Driver + Other Issues

Recommended Posts

With the latest drivers I have been having a list of problems occur with only Warframe. 

 

*PhysX can not be enabled

*GTX 780 Lightning from MSI does not maintain the overclocked core speed 100% of the time. Only occurring in Warframe

*Experienced "kernal has crashed and recovered" Only occurring in Warframe

*During reduced core clock speed I experience lag and frame rate drops 

 

No one else having these issues using the current NVIDIA drivers?

MythBlaze-

 

try disabling 'Nvidia HD audio driver' from windows device manager. Used to get that same error from a previous update/driver version and this fixed it for me. Strange, but worked. I noticed that someone else mentioned it on the forums and I connected that the error frequently occurred during an audio cue that looped as it was crashing (such as mag's pull).

 

This probably won't mean much to you, but for other NVIDIA users:

 

No issues with EVGA Superclocked GTX 660.

 

Turning physx on actually seems to be less taxing that it was in U10. Forest Earth does give me FPS drops (down to 45-55) sometimes, but I have no frame of reference to compare it to because the last time I turned on physx was before the forest tileset was released.

 

I did notice that the latest nvidia drivers included an update to the physx engine.

 

If you roll back your drivers, make sure to roll back the physx version as well!

I experimented with 64-Bit disabled and multi-threaded optimization disabled. 

 

I could enable PhysX with 64-Bit disabled.

 

Disabling multi-threaded optimization showed no difference in performance.

 

What ever is going on with this game. All I can say, something if broken and needs fixed on DE's end from what I can see. My "last" option is to perform a clean install of Windows 7. I'm reluctant because Warframe is the only game that I have any issues with.

Update: Issues have been resolved. 

 

Steps taken to fix them:

 

*Clean install of Warframe

*disabled all non essential services in msconfig.exe excluding NVIDIA services 

*set Warframe into compatibility mode for Vista on Windows 7

 

Doing this fixed the downclocking and PhysX being grayed out. This was provided to me by NVIDIA customer support.
