Re: Does having many open comp tabs slow down AE? by Dave LaRonde on Apr 12, 2012 at 5:59:54 pm
Sorry, but there is no standard answer to your question. There are too many factors involved: amount of memory, number & speed of processors, memory & processor allocations, size of layers, type of effects applied, 3D, number of lights and motion blur, just to name a few.
The number of imported files shouldn't matter much.
