IIRC this is a performance tweak to help the game run better on low-performing hardware. Essentially, at a distance, some (less important) objects fade out so the video card has less things to render. This setting adjusts how far away that distance is that things fade out. Lower fade distance means things disappear sooner (i.e. they disappear when you are still closer to them), and don't reappeare until you approach quite close to them again. A long distance means that things will start to get drawn when you are a greater distance away from them (which means that, potentially, a lot greater number of objects have to be drawn, so works better on more powerful computers).
