RAM preview is not playing at the correct speed anymore.
In a 1080p comp, a shape layer is animated in position, the RAM preview is slow/laggy and play aorund 19-20 fps instead of 25.
But if I scrub the timeline, everything is smooth, reactive.
See the video attached, What can I do ?

The latest (November 2019) release of After Effects includes major improvements to our preview architecture. You should see reliable, real-time playback of cached frames.

I also found that if I animate this simple shape layer in an empty comp in an empty project, everything is fine.
But, if I put the exact same composition and shape layer in a project way more complex (by this I mean I create a new composition in my working project, animate the layer in the same way and I preview this composition only, independtly of the other comps), the ram preview can't be real time.
As if AE had to deal with all the assets in my bin, even if they're not in my comp with the shape layer. I know it sounds crazy but I can't find an other explanation with my understanding of AE ^^
