After Effects :: CC Not Recognizing 680M With Latest CUDA Driver

I have tracked this problem with different versions of everything but can't seem to zero in on a cause. This problem seems to randomly occur when I start up After Effects with other apps already running. I haven't isolated every scenario because sometimes it works, other times it doesn't, and still other times I don't need ray-tracing anyway.
 
If I then go about clicking things off and re booting, etc, it will eventually work. This past time I started AE after I already had Photoshop and Premiere Pro running. Safari, Outlook, Power Point, a couple of Finder windows and VLC player were also running. After I closed everything and then started AE first, it recognized my CUDA drivers and card.
  
Then I re opened everything I had open before ... loaded them full of content, went about the business of editing, ray-tracing, rendering, etc. with no issues.
 
I guess I should be happy with a solution that depends on the order in which I open applications and I am certainly glad there seems to be a work around (albeit a workflow stopper). Are there settings in my other apps that are blocking AE's ability to recognize CUDA? A conflict with VLC player?
 
With a relatively new iMac, gobs of RAM (some say is way more than needed), a fancy subscription to Adobe Creative Cloud with timely updates, I'd like to get into that comfort zone where everything just works.
