FPS drop in new area "Containment"

I'm having the same issue. Any outside area of Containment is bad. But, especially so when looking out towards the open area around the leviathans
I have a stock clocked i7 8700k all cores locked @ 4.7 GHz, a GTX 1080, 16 GB 3000 Mhz RAM. All of my settings are set to low / Disabled except for Model Detail which is at High and Anisotropic filtering at 16x all at 1080p. 


Yet, this area is so bad dropping from the inside of building while at 130 fps to running outside and getting as low as 70 fps dips. I see everything maintain around 80ish to 90ish outside; but, the spikes are the issue. Since it's so variable it feels worse than a constant 60fps target.
