Playing Freelancer on an ultrawide monitor

[Nerva]

I've tried playing at 2560x1080 instead of the usual 2560x1440 of my monitor and it was working correctly with no further settings.
It also increases the horizontal FoV and allows you to shoot your opponents in fighter PvP at a higher than usual sideways angle, which may be an advantage. (Don't be too surprised if someone overly paranoid accuses you of using a fisheye cheat.)
