it looks like that Storage Boxes overlapping or having to much blueprints will make the game a bit slower without the GPU or CPU scaling up, they sit nearly betwean 20% and 25% and it makes no different if the Game runs on 4 CPU Cores or 8. If i force the Game to only use 4 Cores it goes up to 10% more.
The Game runs much better after removing every second Storage Crate and removing all unbuild Structures. Storing from 2-4k Items is propably not the big problem. what i think is the Size of the Crate is - becaus they are a bit bigger as their colision boxes so their Back sides are cliping in eachother.
In that Save are about 300 Storage crates and most of them are back to back, if i count that right their are 128 pairs that Overlap that way.
But using the whistle to freez the Bots will massivly speed up the Game. I only Count 100 Bots, maybe i overlooked some because not all have their blue Tag on top. I got around 180 Bots, 77 are inactive without Code and i do have not the same Effect in my Save after the whistleing.
