I have not played since GU3 and came back today to play again. I got the recent patches and logged onto my reaver and noticed my sensitivity was way too high. I logged out and closed the game. Then I went to edit the useroptions.ini, as I had done before, to lower the joystick sensitivity field to my prefrence (0.600000) and saved the file then closed it. When I went back in game the sensitivity was still very high. I closed the game and re-opened the .ini file to find that my change to sensitivity didn't stay. After multiple attempts and failures I can only conclude that the we are now unable to set custom values lower than the in game thresholds like we used to. Is this a new feature or a bug?
