August 2021:
The same issues still exist today. I've also looked up some older discussions on this matter. It turns out that server lag is an issue that
always existed. Take for example:
These posts are just a small selection of discussions on the Forums over the past 7 years. You (the reader) can make up your own mind about what this tells you.
April 2020:
This is probably one of a billion threats so far about the server lag. However, I wanted to mention that I have played this game since it was first available to the public, and I have seen some bad lag in the past.
After a few weeks of not playing, I couldn't help but notice that the lag on the EU server currently is extremely bad. And I mean, really really really bad. I have never seen the lag is so bad in this game before. I have seen some hiccups where server lag was temporarily extreme but that was temporary. The current lag is constant and that makes a hugely different experience. Since ZOS wants to see constructive feedback on the game on the forums, I present the following issues caused by lag:
- Abilities don't work by pressing the designated buttons unless you press them like a monkey on speed.
- Dodging doesn't work
- Getting stunned or knocked in the sky (such as with Take Flight) literally is delayed by several seconds and gets you glued to the ground for several seconds.
- Snares completely glue you to the ground and disallow you to use any ability or form of movement.
- Enemies dodging your attacks renders them invulnerable for not just a moment, but sometimes over 3-5 seconds.
- Damaging abilities simply don't 'land' on the enemy.
- Healing abilities simply do not heal or only after several seconds have passed.
- NPCs are sometimes invulnerable and teleport (slide) over the ground for seconds after being stunned.
- Mounting gets you stuck in the whistling part of the animation for seconds.
- People are rubber banding on screen.
- Random loading screens appear in the middle of nowhere.
- NPCs sometimes just appear out of nothing or disappear into nothing.
- Snare immunity abilities (e.g. from Forward Momentum) don't activate at all.
- Hard CC immunity abilities don't activate most of the time.
- Hard CC immunity after breaking free doesn't activate most of the time.
- Breaking free doesn't work > half of the time.
- Animations of abilities often do not work or do not show their visual effect when active.
- Animations of abilities stop halfway through the animation, costing resources but not applying the effect from the abilities.
- After dodge rolling, the ability bar greys out (a.k.a. you cannot activate abilities) for several seconds.
- Activating/using a potion is often impossible unless you really spam the button.
- Damage from abilities 'arrive' seconds after actually dealing the damage. (also received damage arrives seconds after being dealt to the receiver).
- Health desyncs
- Resource desyncs
In short: the lag is killing the PvP game.
It wouldn't hurt the game if some of the ESO: Plus money was actually spent on optimizing the servers or optimizing the games engine to reduce calculations needed on the server-side of the game.
UPDATE for PvE issues:
- Bosses lag out.
- Skills do not fire.
- NPCs are 'sliding' on the ground, and are often impossible to damage while they are 'sliding'.
- Random serverside lag spikes instantly kill players.
- Lots and lots of desyncs of resources (health, stamina, and magicka).
- Delayed resource recovery.
- Delayed damage 'hits' from direct damage abilities.
- Delayed heal 'hits' from direct heal abilities.
- Slow rendering of serverside content.
- Rubberbanding of players.
- Stuns caused by NPCs are delayed (delay between visual and actual effect).
- CC immunity after hard CC often doesn't activate and leaves you open to a series of stuns (obviously caused by serverside lag) draining all your stamina (if you still have anything left).
- Breaking free is sometimes 'blocked' even though the client-side of the game indicates that enough stamina resources are available.
- Resources sometimes simply drain without reason.
- Activating a buff or heal over time does play the visual but doesn't actually take into effect.
- Activating potions: well..good luck with that, it is nearly impossible.
- Light or heavy attack weaving is nearly impossible due to lag.
- Health desyncs
- Resource desyncs
- Random loading screens in PVE environments in random locations
- and the list continues...
