Reduced FPS in the editor on MacBook

Unity 2019.4.13, MacBook Pro 16

Previously, the FPS in the new clean project was about 4000-8000. Now it is about 80-100. I don’t know when it happened. Possible after upgrading to MacOS Big Sur. Did something go wrong or was the FPS calculated incorrectly before? What FPS numbers do you have on an empty clean project?

Use the Profiler to check what Unity sees as the hold up.

12.4ms is WaitForPresentOnGfxThread. Render thread is empty

Unity doesn’t use a discrete GPU for some reason. Maybe it affected the FPS?

If your scene is too complicated to run fast on integrated graphics, then yes that would impact FPS.
