Updated to 2021.3.3, why did my FPS drop significantly? (over 350fps)
I upgraded from 2020.3.23 to the newest 2021.3.3 and without having added or changed anything in the editor I see a concerningly large FPS drop and increase in SetPass calls. (Build time is a lot longer too)
The left side of the image below is the old 2020 editor with it's build below, and the right is the 2021 editor with it's build too.
In game they are both looking at the same part of the map for these screenshots, but the fps difference is consistent everywhere, even in different scenes with fewer objects. When updating it said it had to update the materials too, that's the only thing I can think to have changed. I've compared the settings in the editor for quality and resolution, and both versions match up.
I only updated to be able to use the decal projector, but I'm concerned about the fps dropping exponentially if I go forward with the new editor (but I really need that projector). I'm using URP for a 3D game if that helps.
Is there something I'm missing that the editor has changed in versions (like how textures/materials are handled?) that could be causing this drastic of a change?
