I’ve done some DNS testing (central europe),
I’ve been using Cloudflare 1.1.1.1 for as long as I remember - the sim has become completely unplayable for the past few days with it.
The Cloudflare WARP app somehow helped a little, I don’t understand how since it’s the same IP
Then I tried Google’s 8.8.8.8 - No more low bandwidth messages, although speeds were still low
Then I removed my DNS settings and let the PC use whatever my ISP provides - No low bandwidth messages or live traffic warnings, ~50Mbps download from the sim.
(Each change was followed by ipconfig /flushdns)
Far from maxing out my 500Mbps connection but at least I can fly now.
I still don’t understand how DNS settings can affect download speed however, and I really wish Asobo/MS would change whatever it is on their end, because I can download Steam games at 60 Megabytes/s easily.
