Good work on the editor performance improvements!

Unity Engine

I just briefly tested 2020.2.0a7 with the project from Case 1108597.

After a first hurdle that appeared as an editor crash (Case 1238901), I’m positively surprised.

I’m positively surprised of a noticeable editor performance improvement in this build! :smile:

It’s the first version in years where playmode with Case 1108597 isn’t awfully slow. The editor UI is still lagging behind and it’s not too much fun to use, but overall it seems 2020.2 isn’t a step backwards.

I haven’t looked further into this release, because I didn’t want my initial happiness to vanish.

In that sense, thumbs up for the good work! You’re on the right track. Keep doing what you did, please don’t finish half-way and working with Unity could actually get fun again.

The progress bar for when the editor is busy is a really nice improvement as well.

Probably the first time I’m seeing Peter77 talking of being positively surprised from editor performance

It would be great to backport this editor performance improvement to 19.3.

I hope it stays that way until the final version, and it’s not just a bug because somewhere a feature doesn’t work.

Seems like Unity is on right track by adding those new features you don’t need anyways into packages and focusing improving editor performance and stability!

Where are the charts? Where are the cold, hard numbers? How can I believe anything you say without the stats to back up your claims? Who are you and what have you done with Peter77?

:wink:

@Peter77 did you test your project in 2020.1 as well? 2020.1 comes with changes to the C# code optimization workflows.

"Unity’s Code Optimization setting has two modes.

  • Debug Mode, which you can use to attach external debugger software, but gives slower C# performance when you run your Project in Play Mode in the Editor.
  • Release Mode, which gives faster C# performance when you run your Project in Play Mode in the Editor, but you cannot attach any external debuggers."

Release Mode is the new default. Are the improvements you’re experiencing related to that or is Debug Mode performance improved as well in 2020.2 compared to previous versions?

Yes I did. I don’t remember what version I tested, maybe b4. I didn’t have the feeling editor performance improved in that version, but I also didn’t profile editor performance, because it just felt like nothing changed to earlier versions.

That was my first thought too when I noticed it runs significantly faster and then switched to debug mode to find if it’s related. But even with debug mode, it’s significantly faster than earlier Unity editor versions. I also didn’t profile, it’s just a feeling at this time, so I have no data to back up my impression.

PS: Please don’t forget this one .
