Resolved Performance Issues in Unity Editor on Ventura (2021.3.10f1)

Strange, I can go hours without any lags. Maybe some plugin does trigger that?

 

I don't have any plugins installed, only fresh and clean Unity and lags occur

 

Does anyone notices different behaviour when Mac is powered and when it's in energy save mode from battery?

 

I've looked at the latest changelog for 2022, but I cannot find any mention on this severe performance bug? Given the previously mentioned bug ticket mentions that "the code was changed in 2022/trunk", does anyone know if this is not occurring in 2022.2? Or is is simply not mentioned in the known issues? @peter_hall any info on this would be greatly appreciated, as Unity is not usable at this point in time on the new macOS update..

 

Yeah, it's not in the known issues, which is a shame considering the severity of the problem. It is still in 2022.2.0

 

I'm using an Intel Mac
Ventura 13.0.1
Unity 2021.3.14f1

I actually don't have the problem of lag, but Unity is using a lot of CPU
my actual problem is I wanted to keep looking at the Editor.log by using tail -f
but this message is constantly being written to Editor.log all the time:

*** make sure you understand the risks before trying this ***

I tried starting Unity as root, and didn't get any of the Memory consumption went from Unknown to Unknown messages any more.

Crazy idea, but may work for special conditions.

 

Worth a try for me.
Do you launch Unity Hub itself as root and then every Unity launched through it has proper performance? Or you have to do the specific terminal “sudo open application” for on a specific Unity version folder?

 

Opened Unity Hub as root

 

Didn't work for me, but thanks for suggestion.

 

I don't think it is wise to run under root superuser and risk third party access to your computer.

 

Moreover, macOs changed access rules to my project, so I couldn't just use it without root later. Need to grand access to my user again.

 

Yesterday a new version of macOS Ventura got released, has anyone tried it yet?

 

Saw some people on MacRumors ranging from "it's all fine" to "even the system Settings app window hangs when clicking iCloud"... myself I have skipped it.

I retract a previous comment of mine then. Maybe not worth a try then (in my situation that is).

 

For me Ventura itself has been working fine, but this Unity issue still persists even in the latest versions.

 

i had to downgrade macOS to be able to work again.

from my experience, every node-based ui triggered the massive lag, either shader graph or visual scripting. whats funny, in playmode i could patch without lag. but in edit mode, the editor is not usable on ventura.

btw. i tried all available versions and pipelines. my machine is a macbook pro m1 max.

 

It seems, we'll have to wait the fix for 21.3 or 22.2 a little(!?) longer.

Right now I can't work on our multiplayer project on my mac (even one instance of Unity is hard to use, imagine using 4 instances at the same time). I have to use the desktop at the office until Unity fixes this for its LTS version. So annoying.

 

I also have this issue since I upgraded to Ventura.
The Editor is soooo laggy and each time I run my game even with a simple scene or empty scene, my MBP is about to take off literally. Please, fix this ASAP it's really painful !

 

I hope the new version releases next week.

 

I see that fix version is available in the hub for 2023.1.0a23 ALPHA if I'm reading everything right. Hopefully that could mean something for LTS.

 

After some testing on Unity 2023.1.0a23 I can confirm that editor is now running smooth! So, now we need to wait for this fix on stable releases of the Engine

 

There's a new installer available for 2021.3.16f1, release notes here:
https://unity.com/releases/editor/whats-new/2021.3.16#release-notes

It mentions it, downloading and installing! :rocket emoji here:


Update:
Downloaded, installed, upgraded project and... looks good to me! I only gave it a 15mins test drive but confident that the lagginess would have been present with the actions I did: play/stop several times, enter/exit prefabs, import new assets, etc etc

 

still waiting for it to be fixed in the 2022 version

 

Performance is now better on 2021.3.16f1 but still I have problems with panning. Can someone confirm performance drops when Alt + Mouse panning when you have object selected?
Video:

 

I did some testing on 2021.3.16f1, and here are results:
URP Sample Scene - everything smooth, there is no any slow-downs using panning
HDRP Sample Scene - the whole editor is slow with lights and effects toggles checked. Also there is Pan + Mouse performance drop problem
Standard Built-In - There is Pan + Mouse performance drop problem.

Can You check this issue again on standard 3D Core scene with Default Built-in renderer? Just put on scene random object like Cube, focus it using "F" key and start panning around using Alt + Left Mouse Button. After some seconds everything should start lagging

My setup:
Mac Studio M1 Max, macOS Ventura 13.1

 

I tried updating to 2021.3.16f1, it works great now. But since my team's project is currently in 2021.3.11f1 (everyone else is working on that version so updating the project is not an option yet). So I intent to only update Unity locally to work on the prefabs (and only push those prefab changes up). But every time I open up a prefab, there's instantly some changes being made to the prefab (picture below). I guess the new editor is using some higher version of asset serialization? Is there anyway to keep the fix in 2021.3.16f1 while not also upgrading the serialization thing (or whatever causing those changes)? Thanks

 

I just upgraded to 2021.3.16 and still see the black flickering when v-sync is turned on in the editor. Still work to do on the Ventura version.

 

Have you addressed the v-sync flickering issue?

 

Are you on external monitor, and is variable refresh rate active? I am usually having this kind of problems when I activate the VRR (even on Windows).

 

Is 2021.3 still the only released version with a fix so far? Not yet for 2022 right?

 

Yes, still waiting for the fix for 2022

 

Is there the fix for 2020 version in progress?

 

I've been waiting for Unity editor to become usable for 2 months now. Right after I bought a license. Hell of a "first impression"

 

In the 2021 version, the editor no longer slows down as stated in this thread (which is amazing!), but playback performance in the editor is terrible. Honestly, it's been terrible through not just Ventura but also all of Monterey. During Big Sur, it was fine, but even just a 2d game will have random and then continuous lag spikes, and don't even dare turn on VSync in the editor. On my Windows machine, it's flawless, but I've essentially given up on being satisfied with development on my Mac at this point.

 

It is probably because the throttling. It is Apple's fault. My i9 16" 2019 mbp throttles and then decreases down to 1 GHz in play mode. I don't know if the Apple Silicon macs have a similar problem; but for intel macbooks, the problem caused by Apple. They just denying this problem and responses as "this is normal behaviour".

 

@Thanitsak @timgreenberg it is coming in 22.2f1. There is no mention for 2020.3

 

Great that a fix is on it's way! This should really be backported to all LTS-versions as well

 

That's such a good news, thanks!

 

This is purely on my Macbook Pro laptop without any extrernal monitor attached. Variable refresh rate is enabled (I never disabled it).

 

Is it possible to download 2022.2.2f1 somehow already? Maybe through Beta (but now it is not there). I'm tired to relaunch Unity every 15 minutes...

 

I'm still pre-Ventura and will be for awhile longer. If you live on the edge, you can "die" on the edge.

 

Any ETA for the 2022.2.2f1?

 

Had to downgrade to Monterey due to this huge fiasco of Ventura, Unity was not the only one hit.
Working on good old Monterey for more than a month without any further major issues again.

 

When will it be repaired? This greatly affects the progress of the work.

 

I only got this problem when I installed the "Visual Scripting" package out of curiosity. Since then (and even after removing the package) I need to restart Unity every 10 minutes, as well.
What's strange, however, is that I was successfully using Unity on M1 Mac OS Ventura for months without issues..

 

Still hoping to have fix for 2020 LTS.

 

Any fix in 2022.2.0b16?

 

2022.2.2 just came out, it should be fixed in there (just downloading)
