any utility to fix this?
I remember a few years back I had dark night on my previous Win Vista machine....
Cant remember how I did it.
Now in my night flight I can see everything in the sky and on the ground, it doesnt look like planet earth anymore
See if you can adjust it in your video cards control panel, probably under Gamma.
It would be "game" not "desktop".
Just as Radarman said, and also go download and install fsx ENB 24 hour. You won't believe the difference it will make. Dark nights are truly dark, daylight is bright and sunny.
