The game can never simulate complete darkness. In real life, one's eyes would adjust to allow more light to pass inward after a while. There is no such thing in this game. When it is completely pitch black, that's it. You can see anything, it's discouraging. With no light pollution, you should be able to see extremely far, and very well. The only times when you should not be able to see anything is when there is extreme cloud cover AND it is dark. But this seems to happen quite frequently, and when it does, you can't even see the shape of your gun or your feet. I'm not complaining about it, but I am saying that it is not realistic, as many of you say. I would though, love to have the ability to see better after a while in the game. It would be truly cool if your eyes could adjust to the lack light, kind of like an opposite of the blur effect to when you bleed out.
