Hey, I creating custom optimization system and in one method I am using culling groups. I noticed that when I use own optimization method cpu is much lower than when I use culling groups. I thought culling groups are only taking performance during changes, but they taking cpu every time! :O (Debugger Camera.Render > Culling) with 10k culling groups I have 16ms! Is there something mythical about culling groups I am missing?
