A potential fix for the Aircraft visibility problems?

[raaaid]

i run the game at 640*480 i just tweaked those two things which solved plane invisibilty between one and two km

also have on high the efects and get 50-60 fps inside the cockpit and 80 outside, all other things have it on minimum, shadows for example half my fps

if i chage res to 800*600 i get 25 fps which i dont like

in fact the game is updating itself quite often, i have proofs

i guess they are doing secret minifixes patches with the advantage of improving the game without the anoyance of people in forums wanting this and that and the moon
