Does anyone know of a way to lock CAVOK visibility at a number around 90 or so?  Mine keeps reverting to around 25 and this creates a bright white line around the horizon at dusk.

 

It appears to be a fog line, but it is not because of my framerates as they are around 80 or so.

 

When I manually adjust the slider (under weather), there is no hit on framerates and it looks much better.

 

Thanks,

Wondering this too!
