Program to adjust gamma for games?

[Hecktec]

I want to know if there is any program out there (Preferably free) which would allow me to adjust the gamma setting for games. The Nvidia Control Panel color settings applies to the desktop and videos, but not games (would've liked to have Digital Vibrance for games aswell)

Any ideas?

Yes powerstrip works very well for gamma, I frequently use it with games and movies. But you say the nvidia gamma and digital vibrance don't work? They did the last time I tried em, but you're right I just checked and they are now for desktop only, wtf? I know nvidia likes to remove functionality in their drivers but thats going a bit too far.
