surprisingly the game has been running great since the release of morrowind. i've been playing every day without any problem at all. unfortunately, today, after the last forced update, that time of luck was over. now, everywhere, i have a mysterious drop of framerate from more than 80fps to 1 to 3 fps every 5 seconds

it doesn't matter if i'm fishing without anyone around or in a very populated area: every 5 seconds the frame rate drops close to zero.
i already checked my internet connection, it doesn't seem to have any problem at the moment, and the ping is ok. i also confirmed on task manager that nothing else is running... so... i can't understand what's happening. the only thing changed in my system since yesterday was the ESO update.
any ideas?
*EDIT*
i found the problem, but it's not solved: it's caused by "dungeon finder".
when i join a queue every 5 seconds the frame rate drops close to zero while i'm waiting for a group.
