Yes, it is in the roadmap (though I kinda left this one a bit behind due to many other projects). Not just pathing but behavior as well. I noticed this when benchmarking as well but there is no automatic way to do it but it has to be made manually one by one.

idk much about the pathing, but im still gonna ask this, could u make it where instead of just delaying the behavior manager u could stagger it, where it updates a certain percentage of ur population at a time and not just wait to update all of them at once cuz delaying behavior manager alone brings my fps on 1x from 7fps to 25fps but it drops back down to 7fps everytime it updates so lowering the amount updated at once would be really helpful but idk if it would be entirely possible

(also i am vry VRY late game so if u want me to send u my save for testing id have happy to, it is modded slightly so u will need the mods to run it)

(also also u probably already know this but for everyone else, the lag isnt hardware its 1000% the game)
