The multi-quest tracking addon causes lag spikes whenever you switch areas within a zone. You can recreate this by running back and forth over an area where a lag spike occurs. Disable the addon and it runs flawless when you run back and forth over the same spot.
Disable add-ons before complaining about Zenimax imo.
