I have the same issue. "Brightness can only be changed in fullscreen mode" when i am running in fullscreen mode.
I have tried to switch to windowed and back, restarting Uplay but no change. I also tried to alt+tab out of the game and back but that don't work either. I have no way to change the brightness in game.
In 1.4 it was working fine with fullscreen mode.I use it often, especially during daytime and have set up brightnes to 90% as default 50% is too dark for me. I have to change gamma temporarily for TDOriginally Posted by xIHighVoltageIx Go to original post
same bug here, was exactly the same issue with 1,5PTS running in DX12, couldnt change the brightness slider as it always came up with the message "you need to be in fullscreen mode" which I am. Hopefully you can sort it quick. Is there a .cfg or XML file we can change the setting in?
I noticed someone above state they are using an R9 390....well I am to, don't know if that relevant but it wont hurt mentioning it.
