The game after BL has in my opinion just been worse everywhere for fps, I don´t think I personally have stutters but my FPS has dropped with about 40fps even after I have lowered settings. The worst fps I have is probably on Europa and the Tangled Shore. Used to have about 110fps on the Tangled shore now it drops to 70-80fps.
EDZ has also been pretty horrendous with my fps dropping from about 100+ to struggling to push 70fps+
