Spawn Actor Lag

Hello. I have problems with spawning multiple actor.
My project is TopDown. And when i press a key my character does an animation.And spawn 5 actors those goes forward(Projectile Movement).Im spawning these as replicated. There is no problem with replication.And call 5 them with (ForLoop).There is no problems on Server-Side.But i have problems on Client-Side.When i spawn 1 actor also no problem but when i spawn 5 actors.It becomes too laggy. When i spawn them for 1 seconds it becomes anormally too laggy.Why is this happenning ? How can i solve this. Please i really need help for this.

Thank you very much. :slight_smile:

Can you show how you set up your loops?
