Animation 2D performance regression on upgrading to 2019.3 rc

Unity Engine

I upgraded to 2019.3.01f thinking it was the full release (shouldn’t it show up under Beta still when it’s only a release canditate?)

I was using:
2019.2.9f1 with “com.unity.2d.animation”: “2.2.1-preview.2”

which got upgraded to:
2019.3.01f with “com.unity.2d.animation”: “3.0.8”

Both were using “com.unity.burst”: “1.1.2”, but the Burst performance improvement to the Animation 2D package seems to be gone. I’m getting 30-50ms SpriteSkin.LateUpdate() as though the Burst package isn’t active. I tried upgrading to the Burst preview package “1.2.0-preview.9”, but that made no difference.

I’m going back to 2019.2 for now.

Yes, that’s an issue with the Hub that has been fixed in the latest 2.2.1 release. Please restart your Hub so it can upgrade, then it will be displayed correctly.

Could you please submit a bug report with a reproduction project?

Hi, for com.unity.2d.animation:3.0.8, we further improved the performance. However, to have this improvement, you will need to include the following 2 optional packages

com.unity.collections 0.1.1-preview
com.unity.burst 1.1.2

Do let us know if this help.
