Thank you for the input. As I mentioned before, I had a feeling it might have been that the amount of items I have built caused this effect. Which really sucks because I was hoping that I could share the settlement file on the nexus once it was completed. I've been using the SOE (Settlement Objects Expanded) as the main resource to make some futuristic settlements for my play through and there is A LOT on there.
I'm assuming this also means that simply updating my PC specs won't fix this issue?
