Well, I started having problems after upgrading from 4Gb to 8Gb of RAM. I tried everything in here (well ok, read only to about page 38) and then I remembered that the problems started a bit after I updated my RAM amount so I tried taking the two sticks off and whoops the graphic errors are gone. I know for some it wont work, but decided to give my experience here. Im not pleased that I cant use all of my memorysticks if I want to play this game, I love the game when it works but this is not acceptable at all in my mind.
Edit: Yap, as soon as I install the two sticks, it shows graphical error even on the aircraftcarrier, ie. textures disappearing and simplifying.
Edit2: Oh ye and Win Vista 64Bit and Cat 9.8
