    Problem with GPU identification

    nealeh Level 5

      There are already several discussions (some by me) on poor performance with GPU's (Graphics Processing Unit). But I've started this (yet another) GPU thread because it has a different slant and possibly (hopefully) points to an underlying cause.

       

      While experimenting with different settings in my nvidia control panel I noticed in the program files folder an executable - GPUSniffer.exe. So I ran this from an Administrator Command Prompt and it returned this:

      Output from GPUSniffer.exe:

      C:\Windows\system32>C:\PROGRA~1\Adobe\ADOBEP~1\GPUSNI~1.EXE
      Device: 0027EE3C has video RAM(MB): 512

      Renderer string:  GeForce 8800 GT/PCI/SSE2
      Version string:   3.0.0

      Device was not tested for CUDA support.
      Completed shader test!
      Internal return value: 7

      This is in a Vista 32-bit environment. Now CUDA is (from nvidia's website) "NVIDIA’s parallel computing architecture that enables dramatic increases in computing performance by harnessing the power of the GPU (graphics processing unit).

       

      So I'm wondering if the 'Device was not tested" line is a cause for the symptom of poor graphics performance and loss of GPU effects and transitions.

       

      I'd be interested to see what GPUSniffer shows for others with the performance issue and, better yet, from those with the good performance and GPU Effects/Transitions.

       

      I've also found this PrPro CS5 thread with a related GPU problem.
