Hi. Why an alembic file I imported to Blender from Cinema 4d has low FPS while playback? (alembic file link is below)
It is believed that the reason is that more than 4,700 objects are moving.
When you import the Alembic file into the current scene, the animation doesn’t include information in the object, but when you play the animation, it gets information from the Alembic file. There seems to be a delay in reading the animation information.
I don’t know if this will be an accurate explanation. 
Alternatively, use the viewport rendering in the view menu
It can be used if the specifications are low or if normal play is difficult.
