should it not become clearer as you fly closer to the ground?
it should yes, and thats a fact, and contrary to what most here seem to say.

but we will have to live with the lack of dynamics in this area possibly untill dx11 is part of the equation. Its only a game after all. and no other flightsim can claim to do what we are actually expecting in this area. our expectations are under scrutiny here where this is concerned

Gases

Viscosity in gases arises principally from the molecular diffusion that transports momentum between layers of flow. The kinetic theory of gases allows accurate prediction of the behavior of gaseous viscosity.

Within the regime where the theory is applicable:
Viscosity is independent of pressure and
Viscosity increases as temperature increases.[12]

James Clerk Maxwell published a famous paper in 1866 using the kinetic theory of gases to study gaseous viscosity.[13] To understand why the viscosity is independent of pressure, consider two adjacent boundary layers (A and B) moving with respect to each other. The internal friction (the viscosity) of the gas is determined by the probability a particle of layer A enters layer B with a corresponding transfer of momentum. Maxwell's calculations showed him that the viscosity coefficient is proportional to both the density, the mean free path and the mean velocity of the atoms. On the other hand, the mean free path is inversely proportional to the density. So an increase of pressure doesn't result in any change of the viscosity.

Of course this contradicts my explanation but it does prove that gas has viscosity, as far as saying air is less hazy at altitude....thats just fact and I am speaking from 2800 hours of flying experience, the only time I have seen haze at altitude is when passing through a temparature inversion.

I think the sim is on the verge of greatness and I enjoy it very much and don't wish to fall into the negative crowd but find I have to comment on my initial observations as I see them.

Cheers
I agree, the haziness is overdone. It is a bit too dusty not only when you look down at the ground from in the air, but also when you look up at the sky.

Despite that the new graphics are still an improvement.

Default Low level bombers visual

Great improvement on spotting low level inbound bombers over water in the quick missions. Before they seemed to be lost in the waves and now I could see them clearly and judge their approach angle clearly.

Vast improvement.

Well done guys.
