Fat Old Sun

I'm at work, but if memory serves me well, i have Textures and Scenes at High, water at medium and shadows are planar. View distance is set to Medium. I'm running BS on i7 940, 6GB DDR3, 8800GTS. 3 monitors are NEC 26 inchers. On maximum res i start getting weird stutters, not just in BS but in FSX as well. Which might be due to videocard limitations... It's not even stutters but some sort of hiccups every 2-3 seconds. Another question i have, what is the meaning of the aspect ratio choices that we can set in BS options? Some of those ratio choices are wacky. Like a number 4. Or 5.333?

Thank you! Setting desktop resolution to 3840x768 prior to starting the game did the trick. Now BS runs at 5040x1050. Frame rate is somewhat low though, it doesn't look like a useful resolution for my configuration. I went ahead and tried 3 camera option and it certainly looks better then stretching a single screen over 3 monitors. But framerate drop is considerable as well, we just can't seem to win.

Greetings! Does anyone have any success running Blackshark at 5040x1050 resolution? When i set resolution that high, the game hangs on start up. Doesn't even get as far as GUI screen and i have to kill Launcher process in task manager to get back to the desktop. Any help would be appreciated. P.S. I got Vista 64, if it makes any difference.
