Short description of error
Blender 2.82 has a very slow Eevee viewport performance. Even after turning off smooth shadows or AO or screen-space reflections. Not possible to work anymore.
In my model it seems that the slowest is the material_pass, but almost everything is the slowest.
Shading: psl -> material_pass 995.01ms 99
Shading: psl -> material_pass 171.42ms 99
I also noticed that the GPU usage is much higher with 2.80.
