game feels very jerky

so the game doesnt actually completely lock up but its feels very laggy. i went from the game settings maxed out to the game settings as low as they can go and i was getting the same preformance. so i know its not my computer. time will flow but my sim will completely stop moving for a short period of time idk how to explain it better

This is usually caused from stuck sims or massive amounts of vehicles being spawned, but without lots more info could be anything or even a out of date mod if you use mods, if you dont run mods then most likely the stuck or unroutable sims i suggest using nraas overwatch and this mod will help. was going to post the link to the mod but cant sorry, just google it
