So there have been tons of reports of stuttering in-game since the Dragonflight patch came out, and I’ve been trying to figure out how to fix it on my end, since no one’s been able to solve it yet.
There’s also been a bug with the Battle.net app for months now, where you’ll log in and your entire friends list is empty. I just had this happen to me for the millionth time, so like always, I shut down WoW and re-started it, in hopes of fixing the bug (which is how you make it go away).
Upon re-logging in to the game, I checked my friends list to see if I was able to get rid of the empty bug, like usual. The friends list was still totally empty, but after about 20 seconds, it began to fill up (which is common for this bug).
The interesting thing is that as each name reappeared on my friends list, I hit the same stutter/hitching that’s been plaguing me since the patch dropped.
Perhaps the empty-friends-list Battle.net bug could be the culprit here? Maybe Blizzard could finally fix that bug, too, and kill two birds with one stone?
EDIT: I should add that yesterday I freshly reinstalled both WoW and the Battle.net app, as well as reinstalled my graphics drivers with DDU, and am running no addons at all, so any suggestions of taking those steps won’t apply here. I even got rid of all hidden Blizzard data in the hidden folders like $APPDATA$ and whatnot.
