CS6 Global Cache tips?

Very excited about CS6's new global hash cache.

The new "Cache Comp in Background" raises a couple questions in my mind:

For every frame I see in my comp window, AE has cached that frame as well as the frame of each layer and pre-comp (and pre-pre-comp) to disk?

Does RAM Preview now also write the global cache to disk as well as load frames into RAM? (Could it be thought of as "Cache Comp in Foreground"?) If so, does spacebar playback do the same caching as RAM Preview?

If I RAM Preview "Comp A" at half res, and then at full res, does AE store the global cache for the same comps at both resolutions?

So, if I RAM Preview my final comp at full res, is there any need to use the "Cache Comp in Background" command?

Have you seen this Adobe Document and watched the Video? That's a good place to start.

Report

cache comp in background makes a point in time copy of your comp and renders it to disk.

spacebar reads from disk into memory. If you have a slow disk subsystem you may get slower than realtime playback.

ram preview will try and render as many frames until it runs low on memory. If you happen to have render multiple frames simultaneously, you might see "switching to foreground process". This is because it ran low on RAM and is only rendering on 1 process, but will render on disk until it hits the upper limit of your media cache limit.

Hope it helps..
