How can i make my scene less laggy?

So i am making a pretty large map and i am using lots of trees, bushes, and grass, using the terrain editor, and it is very laggy. Is there a way that i can make it so that there is close to no lag with all of that stuff still in it? Plus it is going to be multiplayer if that will help with an answer.

…and now you see why the most visually complex games don’t really do that much, and the ones with rich gameplay have less graphical fidelity. This is a reality of making games; everything is a trade-off between graphical fidelity and functional mechanics.

To make a long story short, it has everything to do with the number of assets that you’re drawing and how powerful the platform running the game (your computer) is. Sorry. Hopefully someone has a better answer for you, but I’m of a mind that if you’re just spraying trees and and brush and grass on a terrain then you’re going to have low fps.

what platform are you on?
