BTW with the new settings, in ATAG the dots are now visible (sometimes) from far away, but they still tend to disappear suddenly.
Farther dots are grayish, a nice effect imho, and closer dots are darker. Maybe as a stopgap measure it's just enough to improve and debug the present dot system (contrast, visibility at all distances, LOD) as pupaxx was suggesting, and adding the radio vectoring system for historical and playability reasons. Then the long term solution could be further evaluated, but with a more playable (and sellable) game.

Cheers!
