>>no pitch/roll anything.
CG_Height in the sub's sim file. Default is 1. In previous games this was a little under or a little over 2. Here you have to be careful again or you'll have a sub doing 360's along its long axis, or end up upside down if rammed or something. One additional thing i noticed was that on deck, in rough weather and this adjusted to say 2.X.. i found myself catapuled onto the UZO as if i was standing on it. My "feet" being launched right off the conning tower deck. So, again, adjust carefully. Hope you like restarting the game alot. (insert DRM rant here).
With stock enviormental settings and waves, i found ehh 1.8 or 1.9 (i forget, but i think 1.8) to be the most i could set it before having the "catapult onto the UZO" feeling.
Hmmm.. i guess the camera doesn't move with the boat?
