Question Unity 2021.2.0f1 Editor Interface laggy and slow - M1 Apple Silicon

Hi, I recently bought a MacBook Air M1, where I've downloaded the latest Unity 2021.2.0f1 Apple Silicon version.

As soon as I started a sample project, I've noticed that the entire editor is very laggy and slow.

Literally when I hover the mouse on a GameObject in the Hierarchy the hovering appears after ~1s delay, or for example when I try to digit anything (naming, renaming and so on), any letter appears only after I typed the next one... very frustrating!

I didn't noticed much lag in Play Mode, but I got ~150fps in a sample scene with a simple Plane and a simple Capsule (with URP), which seems pretty low.

Someone can help me to resolve this issue? Is almost unusable.
Thanks in advance!

 

I have the same issue, for text input unity interface is one letter behind all the time not showing the last inputed letter until one more is entered.

 

I can confirm this is happening on my old intel mac.

 

So I assume is not an Apple Silicon problem, but most likely a 2021.2 global issue

 

Can confirm this behavior on an Intel mac! The editor has a slew of regressions and is practically unusable

 

That's nice. The latest release is 2021.2.0 though. When are you planning on fixing that?

 

Also having this issue. Here is a short video so you can see what the lag looks like.

 

Sounds good... hope will be released soon even though actual release is .0f1

 

Same problem. Unable to work after upgrading to version 2021.2.1f1.
Macbook pro 16 2019 intel core 9.
Is there anything you can do about it?

 

Next week should be fixed!

 

Cool, I'll just take the next week off from coding then.

 

Just upgraded to 2021.2.1f1. The problem is still there.

 

I can also confirm this still happens in 2021.2.1f1
It also happens in 2020.3.21f1
Also, UI gizmos are misaligned and not rendering correctly in place.

 

Having the same annoying bug here with a macbook, (Unity 2021.2.f1) hope this gets fixed soon.

 

Just glad to know I am not the only one having this problem on macOS and a fix is incoming

 

Until the fixed version is released, this workaround seems to improve things enough to make Unity somewhat more usable but still not perfect. Credit goes to ISASTELEPRESENCE who posted here.

Goto Project Settings
Select Windows, Mac, Linux
Go to Other Settings
Untick Auto Graphics API for Mac
Add OpenGLCore
Move OpenGLCore above Metal
Restart Unity
​

In addition, I turned gizmos off in the Scene window since they are not really working.

 

I tried that already. It didn't seem to do anything.

 

Hey, just a quick reminder that it's next week and this issue is still outstanding. Judging by the comments on the two issues open about it, I'd say this is still affecting a lot of people.

 

out of curiosity, would you say this issue is also caused by the same problem?

(obviously I will retest when 2021.2.2 is out.)

2021.2.2 has been released. It looks like the input lag issue is under both "Known Issues" and "Fixes". The performance issue is also under "Known Issues".

 

Happy to report that all is working so far.

 

Okay, looks like it's fixed now. I hope it didn't strain your devs too much with the breakneck pace you took fixing that interface-breaking bug for 1/3 of your users in your first non-beta release.
