Speculative Preview: A way to disable it
My scenes are intense. letting it do it's thing will fill up 128 GB of ram in no time. Having to purge memory every time i come back to AE has given me carpal tunnel. AT LEAST have it respect the skip frame setting. I set my work area very specifically to account for RAM availability at a particular skip frame.

Ok thanks! Very strange location, I'd expect it in the playback area as a checkbox, or in Preferences > Preview. It would be nice if it respected the skips frames selection, so that I could actually use this feature.

Happy to tell you that there's a toggle and a shortcut already available. In the top level menu, simply click on Composition > Preview > Cache Frames When Idle to turn it off and on. You can also use Cmd+Shift+I on a Mac or Ctrl+Shift+I on a PC to toggle.
The ability to respect skip frames in Cache Frames When Idle is a great feature request. Thank you!
