I have found that while in a group the frame drop is worse. Its almost like it is trying to read the parties quest completion even though i have party sync beta turned off.

Also i found if you take your mouse and use the scroll dot on the quest log to move up and down it causes huge fps drops.
Anyways just wanted to update with a couple videos..
Still looking for an update.
