Seamoth in the Cyclops causes major lag

Tyderf

When I am in the Cyclops I normally get 28-40 fps then when I dock the Seamoth my fps drops by about 15 so I get 12-25 fps

Here's video ( It's at the bottom of the page and make sure to keep scrolled to the left because that is where the fps is displayed )
