[2021] constant stuttering after first year in game.

sorry if this has been discussed already. just got the game, just survived my first winter, once spring hit and i started repairing and recovering i started experiencing massive animation stuttering and framerate drops, pretty much my framerate will drop to about 3-5 fps for a few seconds at a time every few seconds, causing my entire settlement to animate in extremely short bursts over and over. i only have about 30 villagers but the game looks like i'm using up all my PC's resources with hundreds of units and complicated pathfinding. any fix or did i just waste 14 hours?

update: after leaving the file open but paused with spacebar for 15-20 minutes it seems to have fixed itself, which is super strange cause i was playing it with the stuttering for like 40 minutes last night and it never adjusted itself, i'm assuming this is a problem with too many stacked jobs/building and pathfinding queues? maybe it just needed time to sort all of it while nothing was happening. NVM it only fixes itself for a few minutes at a time and then goes back into stuttering, i think it might have to do with the active construction queue, is this a known thing? should i be only getting a few small projects done at a time before queuing more?
