Can I tell you what I experience, which is very similar, the majority of desert maps I play, if I fly, I will at some point encounter a CTD like fubar. When playing Totalize I have only CTD three times since 2.2 release, and once had a clean round where I was not shot down and achieved the holy grail of flying for a whole round without getting shot down (yes it was a full server).
What's the trend for me?
I've mentioned this before, a while back in the old forum, I'm thinking it's got something to do with 'force connect' no this isn't Jedi powers, I'm talking about when I am in a plane and someone is waiting to join the server, and they keep clicking on the server name in the connection menu, because I am peaking (I guess) the performance of FH2 by whizzing about in a 109 for some reason I get kicked first, it takes me about 1min to get back into the loading menu only to find the server I CTD from is now full.
