Happening for me as well. The exact same as the videos posted here. What I have found strange is that certain areas seem worse than others. Like, I can do a FATE in Western/Central/Eastern Thanalan and it stutters like crazy. I do FATEs out in La Noscea and it doesn’t stutter at all. I did The Aery as part of my MSQ and it stuttered as well but not as bad as Thanalan. The cutscene after had some skips with the dialogue but it wasn’t as bad as gameplay.

It’s ruining my enjoyment of the game way more than the long ques because the ques I expected as part of an expansion launch. Not sound issues.
