How to make the Unity 5 editor faster

Questions & Answers

I have an old low-end computer and, unfortunately, upgrading my hardware is currently out of question.

I’ve used Unity 4 for prototyping ideas and to learn game development concepts in general, and in that version the editor ran at visibly solid 60 FPS. After upgrading to Unity 5, I’ve noticed there is some fancy lighting going on in the editor, making it slow – I’d say about 30 FPS or less, though I haven’t measured – even in blank projects, and I’d like to revert all of that and strip my project off any new effects, in order to make the editor perform as it did on Unity 4. Is it possible to achieve this in Unity 5?

You can toggle the visibility of lighting on the scene view window controls.

Another thing that may improve performance is disabling Auto-Lightmapping.

Window → Lightning

Deselect ‘Auto’ checkbox.
