You pc specs should handle OHII full with no problems 
Check out you shadow settings in the graphic options in main menu and try to turn down a wee bit. Also try vsync on or off.
Antilag mod may also help if you dont use it already  |
Is it mostly sea traffic? I do notice more boats. Does it fix the boats acting weird, like they don't know where they are going? I see one or two boats in a weird place that looks bugged out, stuck in a way.
