its mostly the overall high fog in the default wfx which gives you more "depth", but actually idk why there should be always fog!
Also i needed to fix some bug in the wfx, because with the default fog settings you have a steady blue tint on everything. YOu can check this, just go to a dark place and there is a really present blue tint!
But if you like this fog effect you will again be possible to manipulate the fog paramters of the Pure LCS wfx.
this is default:

This is Pure LCS (same filter, same settings)

But if you like those always preset fog you can customize it:

and imo thats the whole mystery behind it. Fog covers problems and low quality visuals...
