Sorry if a thread has been created about this already; the search only brought up a few mentions of this issue.
Basically, midway through the fight with Ultraxion, a handful of our raiders have experienced intense FPS hiccups (around 1 fps) for extended periods of time. This has been detrimental to the success of the raid, and we were unable to find the source to the lag.
All of the people were on varying levels of machines and used a variety of addons (from none at all to completely custom UIs).
I've been unable to find a definitive cause or solution to this issue and was wondering if there was any insight around here regarding it.
Thanks
