RAM Preview takes much more time to start with Multi-frame rendering enabled

[guilherme.salles]

When I press the spacebar, it takes too much time to start playing the preview, even with some frames rendered. Also, by the speed it plays, it feels like it is rendering all over again. If I turn off "Enable Multi-Fram Rendering", everything is back to normal.

Version: 22.0.0.44

MacOS: Big Sur 11.5

The slowness to start preview was mentioned in the annoucement of MFR preview (https://community.adobe.com/t5/after-effects-beta/multi-frame-rendering-is-here-aka-the-multithreadi...) - we are working on making it start instantly, it just requires a few more weeks of coding work to finish it up.
