PhysX

Hi,

Apologies if this has already been asked but I have searched for it with no luck.

I rebuilt my R2 this morning and I have the system working great.

I am however missing the nice Audio feature in Control Panel which I'm not too bothered about. One thing that does concern me is no PhysX in Control Panel. This was initially there prior to format. I've used the latest Dell issued Nvidia Driver... Having installed the Nvidia PhysX software I now have the icon back but it reports no PhysX capable adapter. Should this be the case?

I'm going to try installing the 258.96 Nvidia driver in the morn. Hopefully this will fix it.

 

You don't see "Set PhysX configuration" in your nvidia control panel?

If you go to Help > System Information in the nvidia control panel it should tell you what version of PhysX is installed. I believe the latest is still .0513.

 

I would recommend that you uninstall all nVidia-related drivers/software from your current system, and re-install using the nVidia 258.96 driver w/modded INF. That should do the trick for you.

I used the 258.96 package, and have been happy ever since. Stable, fast drivers, full PhysX / CUDA support.

 

I tried the 258.96 driver and the PhysX was present in the properties however, COD4 was affected quite badly.

Using the 257.** drivers available from Dell Support, I was able to max out the game with 35FPS+ with no problems. Using the 258.96 I was looking at only 18FPS. I couldn't understand it... the game EXE was already present in the Optimus white list.

I've reverted back to the 257.** driver now. Cannot see PhsyX within the Nvidia Control Panel Sys Info but I've got back my FPS in COD4.

I can only assume COD4 was running with the Integrated gpu rather than the discrete.

I preferred the later driver... was nice to see the GPU usage on the system tray.

 

Uninstall driver, reboot, driversweep in safe mode, reboot, install new driver.

 

That's exactly what I did... I'll try it once more tomo morn.
