Do any games benefit from disabling fog?

I found in most games, turning off the fog just makes everything look clearer.

Also in twilight princess, when using your senses in dog form, its a lot easier to navigate, since when using senses, it brings a thick, black fog to like five feet in front of you. Turning it off allows you to see a lot better than the developers had intended. Some monsters are easier to fight this way.

I'm going to guess in any shooter, it will allow you to snipe easier?
