My monitor is 1920*1080, and I believe I had the resolution set to maximum. I think what might have happened is because I was in full screen the output is scaled, but maybe the mouse area isn't?
Pretty fun, but I got stuck in the character creation screen the first time because the area the mouse could move in doesn't include the accept button in full screen. Also I couldn't alt tab out of the game or open task manager because my computer was stuck in the game's resolution.
