There is absolutely 100% lag and stuttering if you build a very large house or base. However “large” is a vague term so what is large for you may not be large for me. I once built a mega mansion, seriously ridiculously big. It is completely unusable as the second i get near it, my game (and my friends games) start lagging and stuttering. Im thinking a big part of lag is chests because i did not remember the lag being as noticeable untili build my storage room with about 100-200 chests in it. Once i did that, it was awful.
