Looking reeealy nice there Thomsen!
I haven't had any issues trying it out with my S-Boot so far. Runs really well on my little laptop with a GeForce 8600. The FPS does drop quite a bit when I take the free camera high above the boat, but from the first-person, conning tower perspective it's smooth sailing (~40-50fps at sea, 20-30fps in port or near convoys, which is perfectly normal for this system)
I like that you changed the sun reflection since last version. Looks much more realistic now.
