I'm on Windows 11 and I'm subscribed to Creative Cloud. I have the latest versions of CC installed, including AE, Premiere Pro, Photoshop, etc. (no other add-ons installed).
I have 64GB of RAM installed with a 12-core processor. My sweet spot for memory is to utilize 40GB for all Adobe programs (leaving 24GB for others I needed to multitask).
When I set the 24/40 ratio in After Effects memory settings (which auto sets the same value in my other Adobe programs), I noticed is randomly changes these settings if I close the program and check it again.
I've seen it reset itself to everything from 0GB for other programs (with AE taking up all of my RAM), and even randomly setting it to 56GB for Adobe and 6GB for other programs.
This setting used to stay fixed after the first time I set it, so not sure why it's sporadically changing.
