Idk, I went there only for a short time when there was no one there, just to use attunable crafting stations for the 3 new crafted sets... and I am never going back there....

Not just lag, thats like the staple of Cyrodiil.
Even in BGs, CC break can literally take 2-3 seconds of smashing the cc break button on full stam to work.
Not fun.

Some moderate lag during big fights, but not unplayable.

PC/EU non cp.

However, my fps improved and my ping was ok, too.

Also I have seen far worse lag in cyrodiil.

As a perma-cloaking nightblade main, it's easy for me to judge lag. I move around in cloak. That means I cloak every 3 seconds. This is and has always been surprisingly reliable at most times, so much so that I suspect there is some sort of optimisation in the game where the server predicts you spamming a single skill, despite server performance issues or a wonky connection to the client.

However this does not mean Cyro is playable, especially on a squishy class that relies on accurate play. Spamming a single skill doesn't cut it . Lag shows itself in the fact that, as soon as you try to cast other skills like RAT or Siphoning Attacks inbetween cloaking, those skills fail and/or lead to delays in your next cloak, causing you to become visible. When that happens I know Cyro is or is close to becoming unplayable for me and it is something that has relatively little variation, regardless of your location within Cyro. Once the server is overloaded, it's overloaded and you can detect that at home base.

I am now experiencing this in the late afternoon, with red and blue having 3 bars, yellow only 2 bars on PC EU. I don't know whether they foolishly raised the Cyro population cap, whether they downgraded their servers or whether their supposed block optimisation had the opposite effect from what it was supposed to do. I don't set foot in Cyro all that often, because of performance issues, but it does seem worse to me than last patch.

It seemed ok for like maybe a day, but then I had to go away for work, but I can report my guild has had to cancel entirely group nights or end early due to issues and it's just a constant meme in Discords rn

Tried to play in Cyro today (just a few minutes ago):

Immediately when I tried to log in to character select (for the 1st time today), the login attempt failed before it has even started (!!!), with the usual message about my "internet connection". Which I know is not the problem - go home ESO, you're drunk.

Eventually I managed to log in and load into Cyro... immediately greeted with a steady 600+ ping. Nice shade of red there. 11/10, would lag again.

Ported to a keep which was about to get hammered. Got disconnected right as the hammer zerg got to the outer wall and started smashing it.
I ALT+F4'ed out of this mess and gave up, this is a complete waste of my time.
