Does f.lux affect the color temperature of DirectX video games?

I appreciate what it does on the desktop, but I'm not sure if I want it on in a game.

It indeed affects DirectX games. I checked the option to disable it for an hour, and about an hour into a fullscreen game, the color temperature dropped.

I can't demonstrate the effect with screenshots (both of the captures will have the intended temperatures), but I can show it with a camera:

f.lux doesn't affect fullscreen DirectX games. I just tested it on a fullscreen game myself.

Why? I don't know, but it may have to do with the fact that fullscreen DirectX games operate on a different principle than windowed DirectX games. See this post for the technical details.

I just tested this again, and it's very clear to me that it does affect fullscreen games. Interestingly, I can't demonstrate it with screenshots, but it would be easy to see with a camera. Which game did you try it in? –  Louis Feb 10 '13 at 6:16

Starcraft 2 running on Windows 8. In Fullscreen mode, the color temperature goes back to blinding white (I can tell because it burns my eyes). In Windowed mode, there is a clear reddish hue. –  Jason Feb 10 '13 at 9:51

I just tried it in SCII and it seems this game is not affected. I guess it depends on the game, but I wonder how. –  Louis Feb 10 '13 at 12:03

Easy to find out: set flux to an absurdly low temperature and start a game, it should be obvious.

Result: Yes, it does affect games (as it does movies, even with MadVR)
