Not sure, that resolution worked fine with me. Did you make any adjustments to the settings? You shouldn't have to touch anything, other than the resolution itself of course.
Nothing that I'm aware of, and I've tried both 1920x1080 16 and 32 versions.
Could you perhaps post screenshots of your settings, to see if I made a mistake somewhere? Are there any settings I need to change in the properties menu of the .exe?
Also notice that in a lower resolution (720) the mouse scrolls much faster. It's significantly slower in 1920x1080.
