Streets has what I call a bug currently. In the small camp in the center of the map there is a massive boss and guard spawn happening min. into the raid [10-20 guards as far as I could count] which adds to the rest of the AI. That kills performance. Basically until this boss/guard spawn is removed Streets will be impossible to play. If you want to play that map there are only 2 things you can do - 1. use Donuts and edit the config and cut the other AI spawns to 50% and that will allow for playable fps or go to the center and kill the guards and that will instantly declutter the map of useless AI but it's not easy to do. If anybody knows how to remove the guard spawn there then that will 100% fix the performance on Streets. It's not an optimization issue it's a massive AI spawn issue [separate from the normal pmc/scav spawns]
Thanks for the reply, I never really considered the the boss spawns not counting towards the overall AI count. I've temporarily removed SWAG and currently using SVM to manage bots, pmcs and bosses etc. so I'll remove the boss spawn from streets and give it another try.
