I've asked this before but didn't get much of an answer.
I recently upgraded from version 17 to 18 and I have since noticed an obvious slowdown in how Fusion operates. This is an example of one comp, but it has happened in others.
This one was originally set up in 17, and is very simple, and I never noticed any problems in playback.
Each little number ribbon is its own comp (the blue "light" flashes on and off) and I used Fusion to lay them out and move them around in random directions. I haven't done anything with it since I upgraded a couple weeks ago. But I just went into Fusion with it and noticed the Renderer has a green progress line that was working as soon as I got into Fusion.
That finished rather quickly, but then when I went to play the comp, every single frame required work from the Renderer. Each step was only a second or less, but the result of course was a slow, choppy playback. Even just moving the time head to a different frame, without playing back, resulted in the renderer doing some work. And worse, there is never any finish to the rendering work, even after a full playback. It is playing back about 1 fps, or at best 1 frame per half second. But if I go back to the Edit page, it plays back perfectly fine. I go back to Fusion after that, and it's playing slow and choppy again.
I know this has not occurred in the earlier version.
This comp is simple, but last year I made an extremely complex fusion 3d comp that was getting so complex I had to buy a new computer. That solved the problem of slow render times. But it feels like with version 18, I've gone back to square one. (Yes I can do some work in 3d, but I think I have more than enough computer resources to work in 3d as before.)
Is there some sort of memory allocation setting that I"m missing? I have 64gb of ram and the usage in the bottom right corner is only around 18%. I also notice on the status bar: Playback 1.0 frames/sec.
