Massive performance decrease after upgrading to 2022.2

I upgraded from version 2021.3.11 to the latest 2022.2 beta and suffered a massive performance decrease when using a second camera. I am using a render texture and before upgrading it worked perfect with little to no performance hit. Ever since upgrading to 2022.2 the game is unplayable. My computer is not the issue as I have a 3060 ti and AMD 5800x and it worked perfectly fine before. Does anyone know how to fix this?

here is more context

Please make a bug report for this, preferably woth both 2021 and 2022 versions attatched.

Small tip: quest 2 performance has been improved by 5-15% in unity 2021.3.15+, so upgrading to that would also be nice if you’d stick to 2021lts

Thank you for the tip! Although some of the new features in 2022.2 are useful I think Im going to have to revert. I’ll file a bug report as well.

Thanks! Please share the link if it is on the issue tracker!

yes yes yes!
i have seen this bug report many times.
but still here…have you fixed this?
