Optimizing Terrain

Okay, so according to my friend, using the terrain tool has actually lagged for her more than using normal roblox parts to build a map. This doesn’t make sense to me, because with terrain the game is rendering less surfaces.
I thought her experience was purely anecdotal, but she has plenty of friends who share her plight, so I’m taking her word for it.
She says it could be fixed with “optimization” but doesn’t actually know how to do it.

How do I optimize… a map of terrain? I’ve never actually put time into optimizing anything that’s not code. Does anyone know anything about this?

Terrain is a heavily optimized alternative to parts, that’s the point of it!

If you replaced each 4x4 terrain voxel with a 4x4 Part with the same material, it would look bad and lag worse.

If you’re cool with how it would look, of course replacing your terrain with a few very large parts would be faster.

The best way to optimize your terrain-based game is to turn on Content Streaming | Documentation - Roblox Creator Hub, but then you have to make sure the rest of your game is designed for it.
