Hi,
The sensitivity slider only goes to 0.2 at the lowest.
Fix the slider so it can go lower, or at the very least fix the fact that you can't even go into the settings file in documents and set it lower than 0.2.
Giant desktop displays and multiple screens at high resolution will have higher windows sens and dpi and i understand most people are too poor to get more than one display and this affects less than 1% (assumption, didn't check steam survey data but feel free to factcheck), but nevertheless this is such a basic thing to screw up, and such a simple thing to fix.
As is I am not playing the game because i cannot set a reasonable sensitivity, actually unplayable.
