For those worried about having slow CPUs with the game I have the following:
E6300 @ 3.15ghz
4gb DDR2 @ 900mhz
GTX470 @ 775/1700
And I'm getting over 50fps in even large battles. Sea battles are a little slower hovering around 40-50 so it doesn't like the game is CPU limited much. That's with everything on Ultra but SSAO and DoF turned off.
