I've discovered that only the INGAME toggle for Mouse Smoothing doesn't work. It still affects the option, there is just no "OFF" graphic to display. Check in your User Documents folder for a "DayZ" folder. In it is a file called %Username$.DayZProfile. At around line 292 in that file is: mouseSmoothing=0; If it is a "=1" just make it 0 and your set. Also bear in mind that this is the only direct setting edit right now that I can even suggest or recommend making, don't touch anything else unless you don't mind breaking things. And make a backup first.
