Actually, picking up a dang fellow PA-28 in the circuit can be hard sometimes, so maybe we shouldn't have too high expectations with a realistic rendering making it easy to spot things.
What has been discouraging for a long time however, is the way in previous versions, that aircraft have actually disappeared from view even when they were fairly close and should be visible.
Hopefully that is fixed now so that aircraft never disappear until the range goes beyond the dot-drawing limit. Anyone able to confirm?
