Alright so I have reason to believe that there are specific items, combinations, situations in the game that are causing these stutters. I was having stutters on my deed despite not having really anything. The culprit was the drying grass on the ground. I harvested it and the stutters are gone. This could be the drying grass by it self or a stage in which the drying process is in I'm not sure.
Likely a number of items or combinations of things in the game that cause these stutters. Good luck figuring them all out and solving the reason why they cause stutters.
If I run into another one of these things that cause stutters that I would like to have on my deed I'll probably quit the game. Because the stutters are beyond annoying.
I'll also add that I did take a trip through "Red HQ" the other day and yup stutters a lot. My frame drop is only about 10fps but it's a stutter so really the drop doesn't matter as the game freezes all the same. I have ran through a couple of other settlements that were causing stutters as well.
