I am running Win7 Ultimate and have tried running Powerstrip with in the game "Day of Defeat Source" which runs on the HL2 source engine.
I can set my hot keys to brighten my screen (as certain maps are really dark and the sun on my screen makes it impossible to play). But I enter the game and press my hotkeys and nothing happens in game. My Desktop is all brightened up as I would have expected the game to be, but the game there is no change.
I believe the games runs on Opengl and I am running Nvidia GTX 460 in SLi mode.
What am I doing wrong please?
