Foggy at high altitudes

[ldavid88]

I've been using FSXWX for quite a long time now with P3D v3.4 and am very happy with it.
I've noticed that when flying at high altitudes, it always seems that there is a foggy weather (see picture below) even when the sky should be clear.

Do you know if there is a way of getting rid of this?
Thanks

Indeed, this looks foggier that it should be.

Have a look at http://www.plane-pics.de/fsxwx/forum/vie...php?id=157 and check if this might be the problem.
