right now on a pc screen/monitor the il2 aircraft LoD models at medium and far distances blend in to much with the terrain and background, and they should stand out more !
object visibility distances for spotting, tracking, and identification of objects (trucks, planes, tanks etc..) is 50 to 70 % less than what it is in real life.
we cant be expected to permanently fly in the max zoom view, and should see those objects correctly when we select the "normal" FoV (being "normal" for our specific monitor size).
ideally during initial game installation you should be asked to enter your monitor size , and this would then set the correct FoV for the "normal" default view. you can then still have a zoom view set to another key, and a max view to increase situational awareness when needed.
that should then start people with the correct object visibility (if the il2 objects stand out enough against the 2D terrain being seen on a pc monitor), and they can still go and edit it in the setup options for their FoV if they want to change it later.
