My Brightness bar has been broken since the new expansion launched. Whenever I try to adjust my games brightness, whether it's an increase or a decrease, it automatically reverts to the default. I've installed every update possible, and this has led me to believe that this issue is on the part of the game, and not my computer, as I have seen some other people who have also been experiencing this same issue. Is there any fix for this? I use a Lenovo P51, with an NVIDIA Quaddro M1200 GPU.
