Same thing for me. Since this last version (the one before the 'optional', which I also downloaded), the connection has been horrible. Warps like I've never experienced in AH before, lag kills, getting pinged from planes that to my view are at impossible angles. I'm looking at the entire top view of a plane at the same time as taking on damage. Consistantly. For almost 7 straight days now, my routine has turned into logging on, engaging, yep - same situation, logging off. Very frustrating.
I check in a couple times a day everyday for a 1/2 hr to see if it's straightened out. Hopefully it will before it goes pay to play. If not, I'm afraid I'll have to hold off and wait for word that it's improved - which sucks. I don't think I have a choice though - it really *has* been near impossible for me. I'm still planning on signing up the second it goes pay if this improves.
Btw, trace routes, ping times, and packet loss to the server has been fine, as always. ADSL, and green beacons. Also, the problems I describe have *only* been since this last version. AH had been the most trouble free online sim I've ever played. I'm at a loss here.
