    After Effects CC Lost CUDA Support

    SRStudio

      We're having an issue using CUDA GPU rendering on both Premiere and AE.  The editor has mentioned that output has recently begun to stutter and skip, and after a bit of digging he noticed that neither program was utilizing CUDA as expected.

       

      We're on a Mac Pro 5,1, 12GB RAM, 3.06 GHz 6-Core Xeon CPU, on Mac OS X 10.8.5.  The graphics card we're running is an NVIDIA Geforce GTX 680.  We have reinstalled both the CUDA (v. 6.0.37) and NVIDIA (313.01.04f01) drivers without any change in behavior.

       

      What we're seeing in After Effects is this:

       

      In Preferences>GPU Information, we are unable to select 'GPU' from the Ray-tracing dropdown.  The message "GPU not available - incompatible device or CUDA driver' appears.  Under the CUDA section, it is entirely greyed out and Driver Version is listed as 1.0, despite us having version 6.0.37 installed.

       

      After some digging around I found a tutorial for setting up CUDA support by adding entries to the cuda_supported_cards.txt file.  Our card is already on the list, but I noticed something interesting when I used the GPUSniffer (as suggested) to get the card information: there is no entry for CUDA, despite the GTX 680 (supposedly) having CUDA support.  I do, however, see it as an OpenCL device.  GPUSniffer output is:
