Hi,
today, we had massive lags while playing Falkreath. It hit only during this dungeon and other guildmates confirmed that they also experienced massive laggs in dungeons, though I dont know if they played Falkreath. As soon as we came out of the dungeon, all was fine again, as well as while playing direfrost keep.
I usually have 60-80ms, in Falkreath it showed about 300-500ms but the actuall lag was much worse. I.e. at Domihause, you had no idea what was actually happening, cause i.e. after the announcement of his scream, the actuall scream followed about 30(!) seconds later. We only finished it by burning everything down with aoe and healing everything too with aoe while the battle looked like a slideshow with atronarchs warping around from spot to spot, rewinds and whatever.
Something's serisously bugged at that server hosting this dungeon.
