What's using CPU in editor?

Hi all

I have 2022.3.4.f1 (but happy to upgrade) and I have a 2D project.

I’ve noticed that when I have this project open, in Editor, not running in play mode, the CPU sits at about 40% to 50% even when I’m not doing a thing.

My assumption is that it’s an asset I have, and this project has some assets that I don’t use elsewhere such as 3rd party tilemap tools and things.

Is there a way to find out what the Editor is doing that might be causing that CPU usage? Again, this isn’t runtime or play mode, just in the editor, in scene view, doing nothing.

Hi @oliver_unity892 !

Where are you seeing the 40-50% number? Is that in Task Manager or something similar?

The Unity Profiler might help you here - you can use it to profile the Editor itself. This manual page here shows how to set it up:

If you’re not already familiar with the Profiler this video might help you get started:

Please feel free to share anything you find or ask more questions!

Hi. Yes, in task manager in Windows.

I’ve set up Profiler but can’t see where to determine what the Editor is doing. Most guides seem to be more geared around runtime assessment of things.

If you switch the Profiler to target the Editor instead of Playmode, it will record and detail Editor activity.

@oliver_unity892 I know this is marked as solved, but if you are stuck you can share a screenshot of your capture (or the capture itself) and we might be able to give you some pointers.
