For me, this is a problem. The fog is omnipresent, like a static element that even real weather can't disrupt. Visibility changes only in a degrading direction.

Not at the moment - mostly sunny spells and good visibility.  Where I took the screen shot it was mostly clear with good visibility IRL.  Over my boat in the Midlands the weather is quite sunny, but in the sim it is gloomy.

Current viz in UK is 5 km:

For instance with an inversion once airborne you may well find surprising how the visibility varied from what you expected from down bellow...

This is the haze in my current flight over the south UK. It does look excessive considering the weather today.

I can assure you as a GA pilot of a 4-seater light  aircraft who flies from Cardiff airport...that screen shot is spot on in terms of visibility and haze. The UK has recently been sitting under an upper level high and very slack low level winds. There has been and still is a temperature inversion sitting over us which traps aerosols. High resolution satellite images of the UK and much of Europe clearly shows low level haze trapped under this inversion. Honestly now....your screenshot from aloft is perfectly accurate and is what I observe each time I fly in real life. 

Because of MSFS 2020 and 24 we are lead to believe the atmosphere is always clean with almost unlimited visibility. In reality it's the contrary. So when we see haze in Xplane we believe it's not accurate when in fact it is spot on.

I get haze and inversions. The op says the visibility over the UK is 5k, but it isn't here. All day where I am I can see for miles and miles from a high vantage point 

I was over the Solent with XP12 real weather reporting the visibility as 17 miles, but I virtually couldn't see the Isle of Wight, Southampton or Portsmouth. 

I love the way XP12 is portraying the clouds and haze, but it appears overdone to me. One of the reasons for checking out XP12 is because MSFS is quite poor regarding visibility.

Here's an example from the plane....notice the haze in the distance and this was on a really good day. Normally it's worse during an inversion.

If the weather conditions were as depicted in XP12, but in reality it was sunny with good visibility.

I am very impressed with XP12's depiction of the atmosphere, but the haze amount is not matching up to the reported visibility in X-Plane's live weather.

In a real aircraft I have seen haze that reduced visibility to a few miles too. I remember once on a training flight in a Piper Tomahawk over Kent I could see the Cardington airship hangers in Bedford.

Remember I'm in my first couple of days testing XP12, so in time I'll get to see how haze is depicted in very different types of weather, but as of now I think it is overdone

That's all understood. 

Try spawning say in Yellowstone in the mountains where the air is normally exceptionally dry. No haze...can see for miles which is meteorologically correct. 

For me the haze adds realism and depth to the atmosphere where appropriate.

But I still think @Litjan's explanation of visibility representation in Xp12 helps understanding why we sometimes find it a bit more "hazy" than expected / reported...

Yes, done that 🙂

Absolutely and this is one of MSFS 2024's problems - it is normally clear all the time.

Just heard from a little birdie...

Wait for beta 7 😉

Just completed a flight from the South UK to the Midlands.  Even though I am perceiving the haze to be overdone, everything else in the atmosphere was great - best representation of an approaching warm front I have seen.  Found a setting in the Map Enhancement tool that has improved the ortho.  I was in real time so I saw lights come on - best night lights I have seen.

Being able to see traffic much further away has been superb.

Try a dry destination. No haze/fog 🙂

MrBitstFlyer -  "Found a setting in the Map Enhancement tool that has improved the ortho" - care to let us know what that setting is?
