It wasn't that at all, it was that most tweaked the setting to make it "not" night. So to keep up you either messed with your settings, or you logged. Thankfully, most logged. All we need is another way to game the game.
Yes they did. Thing is had they simply calibrated their monitors correctly to begin with which would have improved the quality of whatever you were looking at in game or out. They would not have had to turn gamma up to make it "not night"
At first I used to mess with the gamma settings too. But then I thought "maybe my monitor isnt set up right" and I discovered a calibration site. When I was done not only could I see in game at night. But everything from movies to websites in general looked better too and I no longer needed to mess with the settings at all. In game or out
Currently very little if any monitor setting changes are needed to make it not "night anymore" and you get the added benefit of an improved and more stable frame rate. At least I did.
