Would interest me as well, I get the same issues as
Conveen,
everything works fine except when trying to walk around, any view that is from the Captains View just freezes the screen but the game continues as normal.
It seems to only happen when running aspect ratios that the game does not offer by default, for instance, 3440 x 1440 (43∶18) works perfectly.

I also tried your recommendation of trying D3DWindower or DXWind and running it windowed, unfortunately the problem still remains, was worth a shot though.
I'd really love to know if this can be solved as, it almost works, and it looks really amazing otherwise.
Edit:
I also found more information on this site:

Not sure if the 3ditor can help, any takes on it?
