I feel like this should be answered somewhere already, but I cannot find any info on it.
I just upgraded to CC 2014 and am trying to get Premiere to render with Cuda or OpenCL as I was able to do in CS6.
I have the Mercury Playback Engine Software Only grayed out and have tried everything to my knowledge to fix this.
I am on an iMac and have found solutions with PCs changing settings in the Nvidia Control Panel, but Mac does not have an Nvidia control panel.
With CS6, I was able to add my graphics card (GeForce GT 650M) to the "cuda_supported_cards.txt" or "opencl_supported_cards.txt", but in CC 2014, these files do not exist. And if I create the file and add them to the package contents of Premiere CC 2014, nothing happens.
I have the latest Nvidia Driver installed:
CUDA Mac Driver
Latest Version: CUDA 6.5.25 driver for MAC
Release Date: 11/19/2014
And that didn't help.
If this helps, here is what happens when I run GPUSniffer through Premiere:
I will be in CS6 until I can figure this out.
I thought the bottom limit was 1GB for CC, so that must be why the sniffer tells you of insufficient memory
