Hello!

Wheres the problem in Unity editor when it gets so slow and laggy when you have worked a while on a project?

I have a super fast and strong computer with 25gb ram. Its not using more than 13gb atm… but so slow and laggy…

I have spawned 11 000 rock prefabs (small decor stones without collider ,with lod level and low detail on texture…)
And I have 10 000 sticks and stems also just for terrain decor(small, no collider, lod and low detail on texture)

And then rightaway when i inactivate these one of them or both the editor is fast again… I mean, come on? Its nothing… what can I do?

You can use Unity’s Profiler to find what is causing the issue. Here are a few resources that should help you to get started with the Unity Profiler.

The cpu usage is going to the roof… when I inactivate my 11 000 stones and 10 000 sticks/stems it reduces it alot…Looks like my objects gets rendered with the cpu… anyway to define gpu rendering on objects? Like stones and such
