Footage lagging

[AtomicAnt]

Hey guys. I'm trying to export a footage that I made in AE and compiled in Premiere pro. 
I had to export it in AE so I coul make it lighter in Premiere, but somehow it is always lagging, even when animating in AE. 

What can make it lag?

Thank you!

What are the complete computer specs, including hard drives (how many, what kind, what is on each, what capacity, and how full)?

If NVIDIA graphics, make sure to use the latest Studio Driver from NVIDIA (NOT the Game Driver).
