Question about disabling actors with particles

Hi! I need a a bit of your experience and knowledge.

I’m making a weather system for my game, and for the different weather types I’m using different actors to have more control about everything, . the question is. if I set for example the actor for Rain to “Hidden in game”, whis actor will consume resources from the computer? (Memory, etc?) or is just like the actor never existed?

thanks in advance!
