There are several games on my computer that are difficult to play because they are too dark. Wolfenstein is especially bad, there is a level that is unplayable because it is pitch black. I have maxed out the game brightness and my monitors brightness but it is still too dark. There was a brightness setting page under Display Properties/ Advanced, but with subsequent display driver changes this page has vanished. Is there a registry setting I can change? Or the System.ini brightness value does increasing this make a difference?

Any advice will be appreciated.
