Feedback (Case 1206572) Editor UI performance regression

And how would that speed up the editor?

 

Yes. 2020 is snappier than 2019 in Release and Debug mode. However, it still is not snappier or equally snappy than 2017 let alone 4.6, which is the fastest editor for me. That is with optimizations such as "Interaction Mode Throttling" in place, which didn't even exist in earlier editor versions.

2020 is one step in the right direction, but there are more steps involved before the performance of 4.6/2017 is reached.

You only need to resize a window in 2017 and 2020 and you immediately feel the difference. If you don't, select the Light or Camera GameObject and resize the Inspector window. It's very obvious that 2020 has a bigger delay than 2017, at least on my PC.

Here is a 2020.1 Debug vs Release comparison from my PC.

• EditorLoop in Debug mode = ~55ms
• EditorLoop in Release mode = ~45ms

However, using Release comes with a different price. You can't use the Debugger anymore. This isn't a problem for artists, but as a programmer, you most likely want to have debug mode enabled always. Which means you don't benefit from this performance improvement. I gave an example why I want this option to be enabled always here.

 

Hi Peter. Do you have any thoughts on the compile time for your project between debug and release code optimisation in 2020.1 please? Release presumably will execute faster but it may or may not be faster to compile which is where change iteration time comes from?

 

The Editor Release / Debug Mode does not seem to affect compile time, I at least can't see a difference.

 

Thanks!

 

Hi guys, just to add some feedback from an ongoing project.

I've just upgraded from version 2019.1 to 2019.3 and the feedback from the editor is just horrible, it is like ten simes slower when compiling script changes os entering play mode.

Without any other changes than the version upgrade entering play mode has gone from 5-6 seconds to nearly a minute, also compiling scripts has slowed down greatly, being four or five times slower.

I highly doubt it is because of the profiler because I've tried to disable recording and changing the record modes but still having those horrible hanging times...

As a developer I've to say that the version 2019.3 is not really viable for any serious game as the waiting becomes such a nuisance.

 

I have the exact same problem after upgrade from 2019.2.2 to 2019.4.9(LTS). I filed a Bug report (CASE 1276540) because Unity crashed every time I modified any script and they recomment to upgrade my GPU driver wich help a little for the crash but not for the performance issue.

I let you here a video comparing the performance of my demo game in 2019.2.2 vs 2019.4.9
