Solved GPU-Z reporting no physx

[stonebear]

I think this is down to an error because Nvidia control panel says it is installed - I am just a bit concerned.

 

[stonebear]

Even more concerned now because I just tried to run Cryostasis benchmark and it says PhysXLoader.dll is missing....

Try reinstalling the driver (download a fresh copy), and select the option to perform a clean installation and also the option to remove the existing driver. This will first of all remove the existing driver and associated files, reboot and then install a fresh driver and files.

It's a issue with the 280 driver. You can download and re-install Physx separately or revert an older driver version.

 

[Dwarf]

Hmm... I've got that driver installed, and as far as I know, PhysX is installed. I'll check when I get back home this afternoon.

 

[smarteyeball]

By rights, the installer should simply detect same/higher PhysX version and then leave it alone. However for some reason, some have reported issues where the installer has buggered physx.

Thanks guys I think I will wait before I do anything, Fluid mark is telling me it is installed and there are plenty of references to it in the registry, also the latest physx download ends with 513 whereas my installed version is 514, weird.

 

[Dwarf]

This is mine. Looking at the list of files, it looks as though you have some missing.

 

[stonebear]

Thanks Dwarf, I think the stuff I am missing is the 3D vision stuff, that shouldn't affect PhysX should it?

I am inclined to think PhysX is installed because FluidMark works smoothly, tells me I have it installed and gives me a score for it. But why is the other stuff (Gpu-z, Cryostasis) telling me it isn't installed?

I have to leave the PC for a bit now so I will check back later, thanks for helping.

I would still reinstall the driver. After accepting the License Agreement, click on Custom (Advanced), and then Next. Make sure that all components are selected (ticked) and then check Perform a clean installation, as shown below. Click Next and follow subsequent instructions.

I installed it today, I removed the previous version, ran Ccleaner then cleaned with Driver Sweeper and then used "advanced" (that is how I had the option to leave out the 3D vision stuff) and I ticked "clean install". Notice that there is no option to tick or un-tick Physx with this version? I assume that is because it gets installed with the display driver.

I might well re-install it again but I really did a pretty thorough job installing it the first time.

 

[stonebear]

I am pretty sure it is installed and GPU-Z is just in error but I am going to try a fresh install doing as you suggest Dwarf - I will report back.

Go into nvidia control panel and set physx for gpu, it'll be set for cpu, I had same issue.

It still doesn't show up in GPU-Z. It doesn't matter I am sure it is installed. Nvidia control Panel says it is etc.

I did I clean install of the driver anyway, I was having some issues with AfterBurner and wanted to do everything from scratch to see if it would fix it. PhysX still not ticked in GPU-Z even after doing as RTS101 suggested again. I reckon GPU-Z is at fault here. It's there! lol

I just hope all this has fixed the AfterBurner issue, the OSD temp display wasn't showing in games for some reason. If not then more Googling! :sarc:

 

[stonebear]

After saying that "I am sure it is installed", I then doubted myself....

I went to the Nvidia folder that the installer extracts to and found the PhysX installer and chose "modify or repair" (I wonder if it was partly installed because there was no actual "install" option there), after running "modify or repair" PhysX is now ticked in GPU-Z!

And on an unrelated side note - Afterburner is now displaying GPU temp in games again.

 

[stonebear]

It seems odd to me that every other version of the driver has had the option for PhysX when you choose advanced install, this is the first time that option has not been there and the first time I have had a problem.
