vjcsmoke, and you can't change this setting in nvidia control panel?
You might want to try the whole process again... as you see, it works for everyone who tried it - for 190.62 and 191.03.

VJCSmoke, try the fluidmark program. the screen your checking is the wrong one. I checked that one too and it says no hardware acceleration but I do have it. thats the old ageia control panel.

What am I doing wrong??

I think for some reason it's still able to detect that there are no monitors plugged into it and thus it refuses to 'put out' physx acceleration?

Man, there's something terrible wrong there. If you have a GeForce Card series 8, 9 or GT200 installed on your system there's no way that when you click on PhysX Control Panel that window appears. What you should see is the PhysX tab of the Nvidia Control Panel, more precisely, this one:

You can only see the other panel if you have an Ageia card or none card at all (GeForce or Ageia).

Genl...I've tested the two test dll's in my system.....Win XP home ed sp2...ATi 3870X2 Ageia PPU.

With the normal SST 9.09.814 none of the demos work but the self test in the control panel "passes" all tests?

In my system the PhysXDevice.dll was not where you described but in the win/system32 folder

I replaced it with the two test dll's but neither worked sadley.....I used "Cubewall" physx bench mark to test as I couldn't get the cloth demo.
It just generated an error message "unable to create scene" and didn't run at all.

I tested the Cubewall with SST 8.09.04 and it worked correctly.

If I can do anything further just pm me.

I ran Fluidmark, it is reporting sofware physx. So the 9600GSO is not activated as a Physx device. Is there some secret trick to make the nvidia control panel ignore that I've got an ATI video card doing the rendering?

when you right click on desktop, do see an option that says nvidia control panel?

vjcsmoke, you have to extend your display to the forced monitor enabled on the geforce card.

shroomalistic, even I dont have that and I have physx enabled.

Will the patch work with the newly released 191.03 beta driver found on Nvidia's website?

So I have to plug one of my monitors into the nvidia card to do this?

Shroomalistic · October 3rd, 2009, 10:10 PM

yeah it works with the new 191.03's and im pretty sure you need a monitor installed on the nvidia card too
