New crazy idea.
I like F.lux
I like it so much that I have my screen on complete halogen mode every moment of the day. I also have it on while playing games.
The downside of this is that I need to play my games in a windowed full screen for it to work. A windowed full-screen however takes more performance than an actual full-screen.
For people like me it would help if games came with a halogen mode as an option in the video settings. It wouldn’t be more than a simple colour filter applied over the entire game but it would make games lighter to run.
