Reposting this issue...
The latest AE does not release RAM on Yosemite. Have installed Memory Freer app which does release it, but this is a little annoying and an issue from an older version I thought was fixed?
We are on Mac Pro 5,1, 32gb RAM.
What is the state of the Reduce Cache Size When System Is Low On Memory preference?
See this page for details of that preference:
After Effects CS6 (11.0.2) update
Its ticked on.
Ticked or unticked makes no difference, RAM still does not get released with using an external app.
