I decided to upgrade from Windows 7 to 8.1 today and I got most of the things working now.
I currently have a problem with San Andreas where changing the brightness ingame has no single effect. It doesn't matter if it is all down to 0% or up to 100%, the brightness stays the same. (Pressing ESC twice doesn't work either.)
I have tried several things but nothing has worked yet. Yes, I tried downgrading my videocard drivers, I completely reinstalled the game and deleted the user files folder in My Documents several times.
My question is: has anybody experienced this aswell and do you have a fix for it?
My specs if needed:
videocard is a Sapphire HD 6870
