Thank you so much for this post. I've been having this problem since Endwalker's release and it's so bad that I can't do the MSQ. Frankly, it's very upsetting falling so far behind in the game when I was so excited for the new story, but because of the near-constant stuttering and lagging of the audio, I can't enjoy any of the voiced scenes, much less the music which makes this game so great.

It's very disheartening to see that Square has largely ignored this issue when there have been so many people reporting it being a major problem, and even after patch 6.01 nothing was done about it (with many that didn't have problems with the stuttering before the patch now reporting that they are experiencing it).

Square, please, please, please look into this. Or at the very least, acknowledge that it's a problem and address it as soon as you can so that we know that a solution is hopefully on the way.
