Question by darkcookie · Aug 08, 2011 at 10:42 AM · lagmap

why does unity lag?

my question is why does unity lag when i add grass and or trees or even when i add animations or textures i noticed that the frame-rate decreases is there a way to achieve greater performance while having a decent amount of vegetation like trees and grass, or what technique should i use while creating a new map to reduce the decrease of frame rate.

One suggestion is go to your terrain and you can lower the detail distance and the tree render distance, depending on how far you can greatly reduce your lag although this does not affect animations

yes i did that but the problem is that the map is a forest and if i lower the render distance the game loads too late and it looks like tree pictures turn into the 3d model ...

by lag you mean framerate drop? in that case it's not lag it's stutter (video). Lag is network related.

Anyhow, you only have trees and vegetation in your scene, i guess, and you're playing in first person?

It must be because of the number of objects on screen, which require more recources. Try reducing the amount and/or size of grass/trees, or lower the graphic quality one or two levels. It should increase the performance.
