Not sure if you tried but: deactivate all your add ons. There are especially problems with ESOHEAD.

Did you open the relevant ports in your router? (see knowlegdebase and search for ports)

so no one can confirm that port forwarding fixes the lagg?

The problem isn't on the user end, it's server. I can hit one of these spikes and nothing will happen for a few minutes, then suddenly like one of the movies where they try to show the passage of time by speeding up action, everything happens, my spells etc go off, people scary by, etc. So the server finally gets around to process things. Broken server code I'd say.

as it is right now, unplayable, but Do i get my game time back, because of the server issues...

My ping while playing this game Is so bad that I can't even get past the freaking intro part without it freezing and then losing conmection because of an unknown error. Bethesda, if youre reading this, please fix the lag problem before I give up on this game.

It looks like my problem may have been my add-ons. After each patch I have to update my add-ons otherwise this happens again.

I live in Japan and have the same issues. The game itself runs smoothly and everything's more or less well and fine... until you try to hop on your horse. The character would just stand still for a couple of seconds and then sit on air for while... only after that the horse appears.
Attacking anything is a really bad idea because nothing happens. After I while you can finally hear some sounds effects and maybe some splashes. But you can also find yourself dead, that's how lucky you are.
My Internet is high speed and high quality (come on, it's Japan, baby) and I never had any troubles with WoW (even on European servers) or any other MMORPGs, so I am more than sure that it's Zenimax's problem.
PLEASE FIX. We really want to play the game. We want to enjoy the game!

And to add some more Points and questions I had to answer:

Yes, I have added TESO as an exception to check load/save files of my AntiVirus

Yes, my RAM is dual channel

Yes, I have updated my DX and graphics - Dudes, I even have updated my GF -> Girl friend

No, I do not run it from USB 2.0 stick - it is on an SSD - and no, this SSD does not stand for Slow Slow Data

Yes, my grandpa has gas and no, it does not interfere with my visuals - only smelling

Yes, my cat eats gras from time to time

And believe it or not, when someone calls - my phone does ring !!

ARGHHH cut the silly questions and solve my Problem !!

I'm with everyone else here and you would think 4 pages of comments would spur them into action. I've been enjoying the game more or less problem free until this morning when I started getting all sorts of lag. Enemies appearing out of nowhere and my abilities seeming to freeze all the while I'm running around and my life is going down with no way to attack back!!! It's probably already cost me 1000gold in equipment repairs. Please Fix. I'm this close to cancelling my subscription!!!

I'm assuming people close the launcher before logging in?

Some have mentioned it helps and I try and close it every time I play. Have noticed lag spikes whilst playing in heavily populated PvP so it's obviously server side issues, but otherwise turning down all settings so only Depth of Field and Grass are on and everything else no more than "high" fixes lag in PvE and medium busy PvP.

Good luck

I have just now started experiencing this today. I cant complete any quests. I can play for a minute or two, but after the first kill, I cant interact with anything or complete any conversations.

If it's latency issues and as the OP states, his internet is fine otherwise, then repairing the game as has been suggested might be the best way to go. Otherwise the previous suggestions on here could help.

I have noticed issues with mouse clicks not responding unless I press Enter for chat or move to an area without enemies and wait so I suspect it's latency issues that need to be fixed on ZOS' side and reported in-game if not already.

Horrible, I just logged in and couldntcast ability at all. Spaming button and no reaction from my character at all.

Really ZOS wtf is happening? Cmon fix this crap

OK, so if you want to check your latency:
1. hit Start+R or type run in search bar in windows start
2. type PERFMON /RES in run window

You will open new window called resource monitor, go to network tab, sellect ESO.exe, click on TCP Connections and there you will see latency in ms.

Here is mine


Now I dont know why there are two of them but as you can see latency is pretty big. In other mmo's it dont go over 60ms

When you serach eso ip you will se that EU server is located in Cockeysville, Maryland

after a day of hell yesterday, crash constantly in cyrodil, i thought id try this morning when it wasent so full, guess what, IT just crashed again, the bug reporrs the game is sending is now full of dreadfull abuse. Ive disabled ALL addons as well, its not my machine its more than enough to run this game and my interweb is fast enough 40/10 fibre.

PVE is fine its just when in a group in cyrodil.
