Optimizing performance for large number of landscape actor tiles

I’m working on an island where I have a simple flat landscape that consists of a large number of square grass actor tiles (around 5000) that I dragged in from the Fortnite Props content folder . They are there simply for cosmetic appearance. I have checked “No Collision”, unchecked “Allow Interact” and unchecked “Can be Damaged”. Is there anything else I need to do to minimize any performance impact? I’m not seeing any performance issues. I just want to make sure I am approaching this correctly since these actor objects by default appear to have a large amount of interactivity built in should the need be there.
