    Receiving no benefit from using GPU acceleration/CUDA in After Effects CS6

    NickRHP

      I recently upgraded the graphics card in my Mac Pro 3,1 to a EVGA Nvidia GTX 680 Mac Edition and have set it up so that After Effects CS6 recognises it as a compatible card as I have read in many places that it should work fine. However, I dont appear to be receiving any benefits to using it, with render times just as long, if not longer than before and previews just as sluggish. I have updated the graphics card and CUDA, set the Ray-tracing preview to GPU and all comps are set to render with ray-tracing, but I still don't get any performance boost.

       

      I have noticed that under the GPU information, in the OpenGL information, the Shader Model is blank and greyed out. I'm not sure if this is related to the problem, but I'm unsure why this is. All of the information under CUDA seems to be correct. I have provided the information below:

       

      Fast Draft:Available
      Texture Memory:1209.00 MB
      Ray-tracing:GPU

       

       

      OpenGL

      Vendor:NVIDIA Corporation
      Device:NVIDIA GeForce GTX 680 OpenGL Engine
      Version:2.1 NVIDIA-8.17.74 313.01.03f02
      Total Memory:2.00 GB
      Shader Model:-

      CUDA

      Driver Version:5.5
      Devices:1 (GeForce GTX 680)
      Current Usable Memory:1.50 GB (at application launch)
      Maximum Usable Memory:2.00 GB

       

      If there is any solution to how to get the benefits of CUDA in after effects, please let me know.
