I decided not to play online due to problems. Other games don’t have this problem

Can confirm that him removing Acuity from Arcane Ascendance solved all my friends issues. Something with that node (and the skill in general) seem to break things and desync the player from the server.

That you found this as a source of some of peoples issues should be able to help the devs to pinpoint what the issue is behind the scenes so lets hope they see this.

Ya Im still getting desync online problems even after the patch 0.9g today

Similar issues as described above, also getting progressively worse echo by echo. After echo 2 I usually quit and stop playing.
Sorcerer build speccing fireball + meteor + focus + black hole + flame ward, no movement skills.
Including my logs in the hopes this gets resolved. Can provide more information upon specific request.

Thanks for the reports, everyone. There’s definitely something going wrong here, but we haven’t sorted out what it is yet. From initial tests I couldn’t cause desync using Arcane Ascendance with Acuity in moderate intensity combat scenarios, but it has been reported often so I still suspect it’s involved.
Additional reports with details of what skills you’re using are helpful, especially if a certain skill or node seems to result in more desync. It would also be helpful to know if this occurs when playing together with other players, or when playing solo online.

My friend who was effected by these issues is running this build: Link
(the skills most used other then Arcane Ascendance by him is teleport and spamming a lot of lightning blasts.

As mentioned above things stopped happening entirely after swapping away from Acuity.
It happened in both solo online play and coop (with me as the only other player) and we tested it both in the campaign and Monoliths.

In the campaign he could play normally but every 4-5 zones or so it would start desyncing him, often quite early in the zone and if he continued playing it would desync/lag him so bad it would take minutes for the portal to even show up and for him to leave the zone. Only fix was to re-log.

In Monoliths he could at most play two echo’s in a row, most of the time only one, before the same thing started happening so whatever it is…its more likely to happen in the Mono system.

So compared to what seem to be happening with teleport where the rubberbanding seem to happen on occasion this almost feels like its something accumulating over time until it just becomes too much for the game.

Kind of feels like it has something to do with:

  • Movement skills (like teleport) since they have had some rubberbanding issues
  • Arcane Ascendance locking the character in place

With the high stacking of cast speed + Acuity ending after 4 casts (which is really quick( you go from being locked in place to being allowed to move over and over, followed by teleporting large distances and repeat the cycle. Wouldn’t be surprised if it somehow confuses the game/server/whatever about where the character is etc.

Will gladly supply any additional info if it is needed and I know its a lot of random speculation in there but we have been quite curious as to what might be the cause.

Keep up the great work!

This is exactly the build and bug I’m experiencing. It seems like some combination of Teleport and the Arcane Ascendance node that makes it last for a set number of spells just throws the whole game off.

Think I have seen a handful of people specify that specific build now and a few others mentioning mage (but not mentioning the exact build). As these skills are very good and very common I wouldn’t be surprised if a good number of the people experiencing these issues are playing just variations of the same build or at the very least playstyle.

As I’m neither running arcane ascendancy or teleport (the most often cited potential culprits), I did some testing of my own unrelated to those two, after thinking it might be a queueing issue (with some posts describing similar issues referring to using numlock to autocast).

I managed to do a full timeline without resestting the game, experiencing only limited stuttering/rubberbanding by stopping my autocasting. The issue occurs when I use right click for my fireballs (main DPS) and hold it. By only casting deliberately most of the time (i.e. single clicks), I managed to reduce rubberbanding to occasional (less than once per minute, less than 2 seconds), with some serious hickups (longer than 10 seconds) during the first minute of an echo).

My running theory to explain this, based on the desyncs and extraordinary bandwidth reports in multiple places: autocasting queues up a lot of events that all want to be transmitted to the server, eventually overwhelming the connection continuously by blocking the download rate through egregious uploading (blocking confirmation packets, etc., etc. → basic network stuff).

The only question that leaves is why the queue isn’t reset/scrapped whenever you finish an echo, as that would seem standard programming practice to me. But assuming it isn’t, or somehow fails to be, the compounding queue could easily block out incoming data, leading to the rubberbanding.

Potential solutions I can think of: regular action queue clearing and network queue sanity checks for a more robust networking system, or making autocast impossible by blocking additions to the queue until the cast time of the currently cast (same) spell is finished, thereby limiting action queue length.

Of course, I’m making some serious assumptions about the back-end here, so I could be way off, but I hope it could at least inspire some debugging avenues. Included are once again my player logs.

I run into my desync issue as a fire minion necro build and necro lich build. Also on my bow rogue build.

Like I can play the game it just requires constant relogging ranging from 30 seconds to 15/20minutes apart which is very frustrating but I am hopeful a patch will fix it. Just gonna have to wait.

Still having issues after yesterday’s update. Some skills feel wonky and desync-ey (maul especially). And rampage still sometimes rubber bands massively (like I give it even chances that I’ll just warp back to where I first cast the ability). And Temporal Shift is still sometimes double casting on Julra or whatever her name is. Teleport felt better when I was playing earlier, but… That’s the only improvement I’ve noticed.

The issue was instantly fixed for me when I removed Acuity, but it’s likely that there are one or more other skills or skill effects that cause the same issue. All I can suggest is to do some gameplay while not using one skill at a time to figure out which one is causing it. It might be something else entirely but I think it’s worth trying.

i respecced my mage so its kinda trash build right now stuck between old/new and havent played(this char) much since i ran into the issue.
Altho it wasn’t happening as fast/bad as it happened before theres def. still something wrong.
Besides the rubberbanding i also noticed weird things(gear desynched?) such as slower mana regen and weird damage numbers before this recording while trying to reproduce the issue (meteor only hitting 10k a whole echo while its doing 40-70k in the vid)

Here is a recording I did with acuity on a fresh game start:

you can see it happening a little bit around 2:45 when the legendary drops and then massive when i join the next echo

for good measure i rebooted the game and dropped the acuity talent and there were no issues afterwards as you can see here:

I’m having major rubberbanding or just lagging out after I use a movement ksill like teleport or focus. Don’t have the arcane ascedance node nor skill.

My character can still cast spells/damage enemies after I use a movement skill. My model can move, but my character is stuck where I teleported to. I can keep teleporting and it wil update my location, and all my interactions will remain where I teleported to. moving will just move the model, but not my actual character.

Still experiencing huge desync with character using Arcane Ascendency + Acuity. No issues on my 4 other characters in empowered rifts.

Transplant does the same thing causing any build that runs transplant for Acolyte to be a suicide mission in high density Echos.

You Transplant somewhere and if you move too quickly after teleporting, you will rubber band in place for a second or two.

This doesn’t happen when using Reap in Lich form and testing on my Rogue, same thing with the dash.

At least for me it appears that skills that move your character like a dash, don’t rubber band (as often anyway), as those that just change your characters location like teleports do.

I do play online and this happens by myself or with other people.

As far as my network goes im running 1200mbs down and 40mbs up, hardwired.

Hello all, thanks for the continued reports. We’ve found the problem with Arcane Ascendance and will be working on a fix.

We’re also aware of issues with mobility skills like Teleport and Transplant causing desync or rubberbanding, but that still needs further investigation from us. Additional reports about that bug are helpful.

What can we provide that helps? I have this issue 100% on teleport, I basically rubber band back every single time I use it.

I’m currently running a shatter build that I got from here:

I don’t even have to be in combat, I can just teleport in the monolith waiting area and I rubber band backwards 100%

So I don’t know if this has anything to do with it, but my desync stopped this morning. The only thing I did this morning that was abnormal was I changed my game resolution from 5120x1440 to 1920x1080, I played one map like that and then switched back to 5120x1440, and I haven’t had a desync since.

I don’t know if the servers are just doing better this morning, or if that had anything to do with it. I’ll see if it comes back and experiment more if it does.

The game feels SO much better without the pop back on every movement ability :slight_smile:
