I have this weird washout look whenever in foggy/rain conditions, especially pronounced when looking at mountains.

It happens with Realistic Lighting Overhaul, Climates of Tamriel, or Ultra Realistic World Lighting.

With vanilla lighting, it doesn't seem that noticeable to me.

Is this a mod thing, or does it happens often in vanilla also? Any pointers on how to fix/decrease this?

I have a Radeon HD 7850 2GB.

Some pics to show what I'm talking about...
