This game is not detecting my graphics card, and is restricting my settings to 1600x1200 or lower, and windowed. There is no option for full screen, and 1080, 1440, etc is not even in the options. Isn't there a command line setting or something to fix this?

You should have checked the "sticky" topic in this subforum.
