having alot in one space isn't bad at all, it's when you starting adding things that you wouldn't think would make it lag, like light fixtures and things, other then that, you can fill that space untill it wont let you add more, but once the animated things come into frame, it starts gettin choppy
demming lights can help reduce lag in highly cluttered areas
