Post-processing layer loading time regression

Unity Engine

Hi!

This is for 2019.4.x iOS platform, Metal, Linear color space, iPhone 11 Pro.

We have this game that during startup is loading scene1 than scene2 then scene3 and finally scene4.
Everything was OK and it took 3 seconds to reach scene4 on 2019.4.4 but then when we upgraded to 2019.4.6 the loading time has gone up to 8 seconds ever since.

The cause of it was that scene4 is the first scene that has Post-processing layer attached to the camera and this is the thing that makes the scene4 load +4 seconds longer.

The problem does not occur on Android platform.

I hope this post will reach a Unity developer that could do something about this regression, I did not send any bug report on this as this would probably bounce off the QA guy as all real bugs do.

Even if a Unity staff sees your issue, they will ask you to submit an issue with a reproduction project regardless, because every project covers different edge cases. The info listed here is not sufficient for anyone to reproduce your issue.
