...maybe it's just me...
...but I always experience any scenery in the distance as being "blurry" whether on the ground or in the air...real or simulated...

...!
Mist, fog, smoke, etc, will always blur objects and scenery in the distance, which is why I always set my sight distance, in the Weather Settings, to 5 to 10 miles max to look realistic...

...!
Take a real flight in a real Cessna 172 at an altitude of 1,000 - 2,000 feet AGL, and you will notice that the scenery in the distance can barely be identified...
