2017.2.0f3 Editor Very Slow?

Some more information and screenshots of profiler from me.

It is explained in dedicated thread:

Something is really indeed wrong here..gc collect calls seems to be excessive... set materials.. too. whats going on ??

 

Same problem here with version 2017.3.1p4.

The editor hangs for about 1~3 seconds when (un)collapsing components. Profiler points out to "GUIUtility.ProcessEvent" which also do a 1.4mb GC alloc

 

2017.3.1f1
It is stated in title of my thread.
Unfortunately I can't send a project folder. But your dev team probably may recreate this issue because many people in this thread encountered with the same issue.

 

I had same problem with 2017.3.1f1 and updated to 2017.4.0f1 today and still have it. Impossible to navigate unity ui.

 

Ok....So.. are the issues been found? If so solution is going to be included in the future LT version of 2017.4? What's going on with this issue?

I have tried 2017.4 and 2018.1b12 But the issue is still there..

 

Same problem here. Editor is choppy and laggy. Sometimes it freezes so much that I have to shut down the process manually and restart unity. Using 2017.3.1f1. Please let us know when some patch will be available. Thanks a lot.

 

Did you managed to recreate this bug?
This bug exist from version 2017.2 and reported from October 2017! There is 5 pages of people who confirm this issue. All Unity versions from 2017.2 is unusable. Are you going to fix it?

 

I've been having weird issues with 2017.x If I tweak the transform components too much, it kind of hangs.. some of the UI still responds, but other parts of it are locked up. Very strange and I have to kill it often and restart.

 

Any idea when this will be fixed? It takes a lot more time to get things done when Unity is so slow.

 

It is really hard to work like this, Unity 2017.4.1f1 64 still not fixed

 

For me, it almost feels like even thou I don't have my scene view opened, it tries to render the scene view anyway, and then there seems to be some kind of memory leak on the GUI side to cause so much memory usage over some period of time and make the editor to crawl to death. The reason why I think this is the case is that recently I had some optimization implement in the game that actually disables the game objects that are not drawn. Which didn't really help much on actual build of the game, but it did help when I was in the editor. But it shouldn't be like that because I usually hides my scene view, because it makes the editor to run slower. But even with that, over the time, the editor gets slowed down to 5 fps and I need to restart again. There has been some mention about the bug has been fixed in 2018 or something like that, but there is no actual detail on what the cause was. So I am not even sure if the fix will help my case if not at all?

 

This is costing us a tremendous amount of time, focus, and money.

Where is the support here?

 

I also have experience the same issue so I narrowed it down to a single custom shader. It's basically a tri planar terrain shader. It does maybe 12 texture look ups so it's sampler heavy.

If I reduce the texture scale transform or set the texture quality settings to low the FPS increases. It seems like it's
related to rendering or some fill rate issue? Maybe the shader passes are getting duplicated?

I double checked on Unity 5.6.5 and the shader runs fine at a solid 60fps with no issue.

 

I have the same issue here with 2017.3.1p3. I posted a screenchot of the profiler here : https://forum.unity.com/threads/unity-2017-3-1p3-is-getting-very-slow.527324/#post-3471227
This is a big issue on my professional projet.

 

What's the status of this issue? It's not fixed in the latest version either.

 

For anyone still having performance issues me and one other found that when we had the performance drops we simply opened up Blender or Zbrush in my case and used it for a few minutes. Then we minimized it and returned to Unity and pressed play to noticed 5x-10x more fps going from 150 for me to 1000+.

-The main issue present for that one was Gfx.waitforpresent in the profiler.
-Having my window maximized or not also affected this.

So do that method and come back into Unity and see if anything has improved. I am not sure what causes the bug but that method to solve the bug is 100% and works everytime it appears for me.
I noticed this bug ever since Unity since the Unity 5.4 series to 2017 latest. I have not tested in 2018.

I also want to say thanks so much for the developers and community taking this so seriously and I hope we make progress!

 

This is a bit random, but it helped me with slow editor performance in the past -

If you have a nvidia card disable game overlay in the geforce experience program.

 

In play mode if you have selected one of your characters that has a lot of components it will be super slow, you have to select an empty game object or at least something with a very few components. I am using 2017.3.1 and its slow for me too, especially when I switch between scenes during play mode or expand/collapse a component or click one of the menus.

Just found out occasionally that it works smooth without network connection. No lags, just go offline

 

Did they fixed it in unity 2018? Anyone tried? I am curious but also worried my project would explode.

 

No noticeable improvement.

 

Same here. It'd be really nice if we could get some additional input on this. There are at least 3 form threads on it that I am aware of. Is the back port for 2017.3 still going to happen? What about 2018.1?

In another thread someone referenced issue 964953, which is tagged as fixed in 2018.1 or 2018.2.0a2 depending on which part you read, but I'm still seeing cases where the EditorOverhead is using well over 80% of the CPU time in 2018.1.f2.

 

"I'm still seeing cases where the EditorOverhead is using well over 80% of the CPU time in 2018.1.f2."

Same here, we're seeing large EditorOverhead performance issues when we open the Profiler, editor then hitches like crazy every couple of seconds..saw it in 2017.4 as well.

 

I've updated from 2017.3.1p4 to 2018.1.0f2 and did notice a big speed improvement when expanding/collapsing components. Not sure about the profiler.

 

It seems to manifest itself once we have a lot of stuff going on, almost like it is trying to catch up...

Seems it is in the ApplicationTickTimer/ Update Scene but nothing shows up as the actual issue - it just has a large self ms time but everything in the hierarchy doesn't add up remotely to the total, our stuff is around 5-10ms, but the ApplicationTickTimer UpdateSceneIfNeeded is taking 300ms-400ms , sometimes it goes to 5000ms+

Investigating more..

 

Ok dropping our visual quality down helped - obvious but this is a high end desktop and we're doing a mobile game, we're not throwing that much at it relative to a desktop app...it was fine on 2017.1 from what i can tell...

Anyway here is a timeline when it happens, obv Gfx.Commands is having issues - once we drop the quality, the hitches are much less noticeable. We do have multithreading enabled and working on Android.

Either way, we're causing a stall but there is still a significant overhead from what we can see in the Editor which maybe amplifying the problem..

*Update - ok we found our culprit, our normal map shader was horrendous in performance...knock is a huge performance drop in the editor..

 

I had exact same issue, and I fixed it completely by drastically reducing number of version controlled files. If you guys are using version control, I highly recommend you to turn version control of, or make not important files private. I have reported this issue before, and it is happening in LCS versions also.

 

One more finding, and I know its been echoed around, even by Unity: having any open components in the inspector panel drops perf by up to 45fps in the editor here.

It's actually the biggest thing between a smooth editor experience and a constantly laggy one. Which is a little frustrating, since to navigate the scene smoothly we have to deselect all objects, and wait a few seconds while selecting one...

 

This is absolutely insane because this is the most performed action on Unity Editor and causes EditorOverhead constantly, unity HAS to fix this or Epic just won the race.

 

Hi, @benoitd_unity , I still got the "EditorOverHead" at 99% in the latest 2018.1.0f2
I am working on the official BoidExample. I don't believe the bug will stay for 4 months since Jan

 

Me Too!
2018.1.0f2
1080ti + 6700k
only ~20fps in editor!
Slow TO DIE!

 

Hey, @benoitd_unity I found that when I close the Nvidia watching program and Geforce Experience, the editoroverhead disappear on windows10

 

Same problem here after updating from Unity 2017.2f to 2018.1.0f. I experiment huge fps drop each 2/3 seconds caused by "ApplicationTickTimer" and "GUIUtility.ProcessEvent()". In my case if i turn off my internet the problem disapear.

 

I agree. I'm having problems with performance in the editor in Unity 2018 within Debian 9. AMD processor/GPU 16 GB ram.

 

I upgraded to 2017.4.3f1 and I can say performance is better (but still far from good) with the inspector window. At least its a step forward, but are there any notions that we'll get actual native desktop performance in the editor one day? For example, just scrolling an inspector tab for an object that has a component with ~50 public variables is hitching and never smooth...

 

Some news, actually its happening only when i share network with my phone (samsung), if i use ethernet it doesn't happen anymore.
I make a screen of the profiler when it happen, mostly when i rotate the camera in scene view, but it cause others weird stuff, it's like unity doesn't respond anymore for a short time.
I don't think that is 100% related to network sharing with my phone, since other applications works fine

EDIT: I can't really give you the profiler data since his size is 695Mo, i have a verry bad upload speed

 

Hi folks, in case anyone is reading this thread, some pointers:

If you're on Unity 2017.x, upgrade to 2017.4.3+ as soon as possible. This is the first release in almost a year we've had in 2017 that doesn't completely drop the ball.

In general most unexplainable performance hitches are gone while doing basic tasks. Some explainable problems are still there (drawing an inspector drawer seems harder than drawing our full 3D game in the scene view and the game view simultaneously with all post turned on...)

Enter play-mode is still ridiculously slow, compiling scripts are slow as well, but at least the editor isn't completely unusable anymore.

 

Hi I'm using Unity 2018.1.3 and this issue is still there,..
The profiler shows a process called AppliationTickTimer which causes lag spikes every 1 second in the Editor.
also the compiler also takes a long time to compile, compared to 5.x which I think it was very quick

 

Is there anything/any tips that can help with the selection of sprites in the Editor? I'm on the latest LTS Unity 2017 version.

My artists are having a hell of a time creating levels and I have no idea how to help them, removing every script/material still leads to the same issue.

 

I think it is fixed in Unity 2018.2,1b

 

same here. Editor becomes completely UNRESPONSIVE when you deal with big PREFABS.

Clicking a big Prefab (1 MByte or bigger with many gameobjects) will cause instant Unity FREEZE

(clicking prefab in Asset)

Clicking prefab in Hierarchy is fine

 

ok Unity 2017 is simple a terrible Build.

I moved now to 2018. 2017 is just too buggie. I doubt this will be fixed ever because it has been released already for almost 2 years.

 

Same problem with 2018.2. Unable to work, empty scene and editor windows are redrawing for ages.

I shut down my internet connection and this completely solved the problem.

P.S. I suspect bug caused by some IP loopback connections established by Unity ( ShaderCompiler, etc.)
