It crashed when I tried to change options to "low" in hope of disabling motion blur (because it makes me physically sick) and now it says "come back tomorrow". I think something's wrong...
If you're still looking into it, I think it would be nice to have the options to change the screen resolution and to play in windowed mode. If you don't mind adding these options, of course - I do not insist, just a suggestion. Still very excited to experience the game when you add a setting for motion blur!
