Improve performance when using effects
Some effects, such as blurs and distortions, require large amounts of memory and processor resources. By being
selective about when and how you apply these effects, you can greatly improve overall performance.
•
Apply memory-intensive and processor-intensive effects later. Animate your layers and do other work that requires
real-time previews before you apply memory-intensive or processor-intensive effects (such as glows and blurs),
which may make previews slower than real time.
•
Temporarily turn off effects to increase the speed of previews. See “
Delete or disable effects and animation presets

Limit the number of particles generated by particle effects.

it. See “
