If you spend more than a few pulls on any boss in any of the new trials FPS tanks in half. We have many instances where you go into a trial and everything is fine until you wipe on bosses for practice fps will go from example 144 - ~20 fps, then you have to leave the instance and come back to get your frames back.

This issue has persisted since before the multi-threaded rendering update and after and has never really gotten any better. As someone who loves the dungeons and trials that this game has to offer, I would love to see something like this looked into, or at least acknowledged as an issue, before releasing more content in the future... It really sucks having to PTE every half hour or hour to refresh frames, and it doesn't seem to matter how great or bad your system specs are its still an issue with everybody.
