You'd probably need at least some so that you don't lag every time the fog changes.

Increasing the server tick rate would help with that. AFAIK Starcraft, Dota2 and LoL all use 30Hz. FPS games usually use higher tickrates. Some fighting games enforce a constant amount of (input and network) lag to make the connection quality unimportant (up to a point).

Unfortunately there's a lot of jitter in real world environments, so you can't really rely on that. : \
