Video of the problem:
I use the Transfer settlements and it tells me my sanctuary has 5000+ objects in it, I noticed some sort of tearing or flickering around the 4000 object mark. Is this a common graphical issue to have? Have I reached the limitations of my hardware/game engine? I haven't crashed while building yet, so this is just annoying visually. My specs if it matters: i7 7700k, gtx 1080ti, 32gb ram
