No - not really; a stable atmosphere where there's insufficient
condensation nuclei or insufficient relative humidity, fog won't form
and the visibility can be quite good. You can also get poor visibility
with unstable air, happened quite often when I lived in Houston.

The general case (unstable air, rough, good visibility; stable air,
smooth, terrible visibility) is just the general case. There are
conditions that can result in something other than the general case. No
particular mystery!
