Fusion Studio:Settings->Memory->Playback caching->Fill cache

Hi all

Just a quick query - what exactly is Playback caching : Fill cache: On / Off / Only if slower than X fps?


It's not described at all in the manual that I can find - certainly not on the pages that detail the rest of the Memory settings. It's shown in the manual's screenshot of the Memory settings, but not then described in the text.

Can't find any references via Google, either.

Thanks.

I'm not sure if it works since I have never changed this and there are a few "unconnected" UI elements in Fusion that do nothing. But the general idea is, that Fusion saves the result of several nodes in the RAM. This is the green line in the playbar. You can disable it completely (which I wouldn't advise when you're working on a composition) or set a threshold that it only saves the results to RAM if the playback speed is lower than the specified value.

If I would ever use this I would usually set this to the project frame rate (or just slightly lower).
But in general I wouldn't touch this at all if your not running out of RAM constantly.

Thanks for the reply.

I have tried it but I can't seem to get it to do anything. What you describe makes sense, but I can't so far notice any difference when it's on vs off. Nothing extra seems to be cached with it on.

Perhaps it's non-functional as you say, which could explain why it's not described in the manual. Or perhaps it only works in specific circumstances, which I'm not meeting.
