2021.1.20 onwards - Extremely slow performance

Unity Engine

I updated my project from 2021.1.20f1 to newer. With 2021.1.22 and 2021.1.23, I get extreme lag even in both the Editor and Game View, even though the “Stats” show 120 FPS during Play Mode. The Game View is so choppy it looks like 5-12 FPS. And V-Sync is broken, the “Stats” show FPS jumping from 50 to 120, back to 80 and 90 every second even though V-Sync is ticked… Low Resolution mode doesn’t help either. Also the Editor has extreme choppiness when it was smooth before (in version 2021.1.20f1). I don’t know what happened, but I never got this when updating to other versions.
I’ve tried removing packages, the Library fold and so on, only thing that works is to downgrade.

[lukasynthetic]( 2020.3.19 onwards - Extremely slow performance members/lukasynthetic.5158804/) seems to have the same problem but when upgrading from 2020.3.18 to LTS 2020.3.19. Could it be related somehow?

This is a known issue for mac, there’s a case link somewhere, fix is coming

Glad to hear!

Anyone got the case link? Some of my players report bad performance on macOS and I’d like to track it and see when it’s solved.

MartinTilos reply in this thread gave more clarity: https://discussions.unity.com/t/857470

the issues are gone in Unity 2021.2 (for my part). Hope that helps
