I have this problem with CC, CC2014 and the most recent CC2014 update. Using premiere, linked comps to AE become unlinked.
This only happens when I use an NVIDIA graphics card (CUDA). When I put in an ATI card (OPEN CL), it works fine.
All CUDA driver updated to latest versions.
I am on a Mac Pro Gen 5,1.
NVIDIA GTX 660 Signature 2
Apple ATI 5770
It seems to be an CUDA problem.
The NIVDIA card is about 30% faster than my ATI card so I would like to find a fix for this.
