Physx has disappeared on my GeForce9400 based motherboard

I have a Gigabyte GA-E7AUM-DS2H motherboard.
It uses a GeForce 9400 graphics chip.
Originally, it had PhysX running with no problems. There was a demo utility that included various demo scenes. It was brilliant.
Now, presumably after a graphics driver update or two, & a number of months of not playing games, I discover that PhysX is nowhere to be seen. Even the demo is gone.
I downloaded another PhysX demo, phluidfysics, and its rubbish. Clearly no PhysX accelration is running on my system.
Curiously, there is a PhysX subdirectory in Program Files
GPUz shows the PhysX box un-ticked.
I've rolled-back the driver - still no PhysX.
Whats happening?
Have NVidia decided to prevent PhysX from being used on anything but the top-end chips?
I can find nothing to tell me.

  1. Physx on 9400GT?LOL,Buddy,Physx needs atleast 32 cuda cores to be enabled in a system.9400gt is not a gaming card and is never a top end card,higher number does not means performance always,a 8600gt is faster than your card.9400gt has 16cores.it cannot run physx in any way.
  2. Scoff all you like mrjericho1991, but I am telling you that it did work, & worked well.
  3. Are you using the latest drivers from Nvidia? I really don't think that Nvidia would pull Physx support for the 9400?

    Check this link for Physx drivers:

    Good luck!
  4. FYI, from Nvidia:

    Which NVIDIA GeForce GPUs support PhysX?

    The minimum requirement to support GPU-accelerated PhysX is a GeForce 8-series or later GPU with a minimum of 32 cores and a minimum of 256MB dedicated graphics memory. However, each PhysX application has its own GPU and memory recommendations. In general, 512MB of graphics memory is recommended unless you have a GPU that is dedicated to PhysX.

    Hi COLGeek,
    Thanks, already tried it. This latest driver doesn't help.

    By the way, I'm running with Vista 32bit.

    Here's a page from the manual that shows it should & did work.

    No argument from me. If you say it worked, I am good to go.

    Have you tried running Driversweeper to completely remove all Nvidia drivers and then re-installing the latest drivers, from scratch? If not, try that. Standing by.
  7. Hi COLGeek,

    Thanks for your suggestion. I'll download Driversweeper & give it a go. Sounds pretty useful to me! I'll let you know how I get on.

    Cheers.
