Sanctuary/Red rocket area ctd

[Malefic]

as the title says. I have both settlements set up using the rise of the Commonwealth and I recall someone mentioning that Sanctuary is a graphics card killer. Is anyone else having this issue

I did use rotc on sanctuary but only one time now, just wanted to see how it was from 0 -3 but now I do it myself how I want it , I did like some things, but I thought there was maybe one too many factories being build for the amount of settlers there's and a little too clutter for my liking, some npc's pathing bunches them up with others, ..
But in terms of graphics sanctuary hill was just fine, tho sometimes the fps was hard to maneuver around =(
Not sure about red rocket , I never got around to using rotc with that, I keep that area for personal storage and to get away from the settlers and whiny marcy never being happy with what was done

I have heard from others here that having both of those build with RotC is a tricky endeavor because wandering around one loads elements of the other because they are so close.
