The level of detail or view distance for aircraft is REALLY short, and planes therefore just pop in and out during my replay. I think the distance is about 1 mile, at which planes just fade into dust. This really breaks the immersion and fun for me, and it doesn’t seem to save any CPU power or anything really, so it seems to be fairly useless.
Also the camera lock feature doesn’t work very well, and tends to sometimes completely zoom into another dimension instead of tracking the plane.
I hope these things are changed and improved in future updates so I can watch my planes landing or doing acrobatics without it popping away when it gets to the end of the runway or whatever.
