Offline AI Traffic seemed much more lively, or it could be simply coincidental. Notably I have AI traffic, both GA and tubeliners, turned way down for FPS impact.
Post-update, I jumped right into the USA Tour, and had to go around at DCA for a jet that simply would not exit the runway.
Taking some comparison screenshots on another circuit of capital later in the evening, I passed a generic (looked like a PC-12) who was instructed to hold short for the Pipistrel on short final (me).
I was taking measurements on my evening flight (Essex to Martha’s Vineyard), I had four GAs around me, one who was completely oblivious to “Traffic in Sight” calls, but it was great seeing more nav lights around me. The sim world is a little more populated now.
