I recently installed Thief Gold along with the universal update, and after tailoring the controls to what is most comfortable to me I began with the training level. I felt the game was too bright so I tried adjusting gamma and much to my surprise it was not working. I tried uninstalling and reinstalling it, but I still have this issue. I also downloaded the game on my laptop and gamma adjust works fine on that. Could someone please help me? I would love to enjoy the game in its native brightness.
