I have a 24" monitor with a native resolution of 1920x1200, which is of course a 16:10 aspect ratio.

I've been advised against using the 16:10 option in Dark Messiah because it's supposedly experimental and 'not supported'.

Can anyone tell me what the problems with 16:10 resolutions in Dark Messiah are? What exactly goes wrong?
