max of 1366x720 is likely why its crashing, The lowest I can set it to will be 1024x768 - 800x600 isn't registered to the the graphic options - The default in game windowed resolution is quote unquote 1680x1050 - but it remains fairly "small" window (theoretically it should be larger than my desktop resolution, and yet, 1600x900 fills my whole screen, borderless, and 1680x1050 actually is bordered window in center of screen....
