How to handle a lot of moving replicated actors

Hello everyone,
I’d like to ask how can i handle a lot of replicated actors that move.

i have for example 400 actors which are all moving at the same time. But if i just throw them in there, the actors are lagging (because of too many replicated values at the same time?)

Now i’d like to know how you would handle this.
My Actors currently are not using any Navigation but it would be possible to add.

Thanks in Advance!!
