Explanation
Okay so, let's say you make a GUI for your game so people can remove and re-add things to the game that are just there for detail... this would be done so people such as myself who have PC's from 2008 could actually play those types of games. With this, the way they remove the items is by removing it from workspace and how they re-add the said item is by cloning the model in Replicated Storage and moving that clone to the Workspace.
Issue
I've been told that doing this will cause lag to your game as your Client can see everything that's inside of the Replicated Storage, although it may not render... it's still visible on the Client side.
Solutions
There are no solutions as this is something I've been trying to properly figure out for the past six months. I'll list what I've looked over.
Thank you to anyone who helps me with this.

perhaps you could fire a remote event and have the server do it for you? so that it doesn't take up client resources
But I do not know if items in replicated storage use up client resources
