If you want a tip, I would suggest you look at a program called nHancer, its built for Nivida cards and is designed to give you control of AA settings in games.
It's fully customizable and has description's about what each setting in it does. Just click on Ship Simulator 2006 when it starts and on the right is the settings from which you can pick from, it takes just a little while to play about with, but when you've got it right you get some amazing graphics.
