What puzzles me is the variety of experiences we are having, ranging from all bad to all good!
For me, WU6 has indeed been good - 3 flights so far, 45min each, CRJ550 in VR, real weather, real traffic, ATC, and all went nice and smooth. 3 very enjoyable flights with some incredible vistas - and not a single CTD since the update!
Keeping my fingers x-ed it stays that way, and hopefully things get sorted out quickly for those who are having a hard time with the sim. When it works, it is so much fun!
