Constant Desync

[Legendary Revolver]

Started playing a game with my friend earlier and once we hit a certain point, I get desync'd every turn with him as the host. My internet connection has been stable with no interruptions, so it's not that. Has this happened with anyone else?

You can use Radmin VPN though to play via LAN. But trust me... there is no difference in desyncs via Radmin VPN in LAN games vs. ordinary online games.

Welp, there goes that olive branch. How is it that Firaxis managed to make a game so full of bugs to the point that it's borderline unplayable in MP (and prone to many crashes in SP too), and never fix ti despite constant reminders that it exists.

Me and my wife play LAN games with no connection issues... But maybe our router is gold.

Too many people have this issue for everyone's router to be the issue. Also a LAN is entirely different than playing over the Internet. The virtually zero network latency probably makes up for some crappy coding on Firaxis's part.

Been trying so many things, nothing works. Shameful

I know it has been awhile since anyone posted inside this discussion, but here goes just in case:

My buddy and I experienced this issue off and on in various games (the games just included the 2 of us plus 6 AI). We thought at first it was possibly due to DLCs or even mods that were installed. However, we experienced the problem with or without mods and DLCs. We then noticed it was varied: sometimes when you saw it you could leave, load a save, and presto it was gone. The next time you do that it is okay for a bit and then it returns like those Barbarians you thought you had taken care of. Other times once it started occuring it would continue every turn until we either finished the game or gave up in frustration. Eventually, we noticed in the lobby screen some of the particpants had small red exclamation marks near their team color. If we hovered over this mark it would say that they had a color conflict with another Civ.

After noticing this we started changing the team colors around to remove these red marks for everyone. Sometimes we even had to replace some of the Civs to resolve the conflicts. Another thing we did was we no longer used the Random Civ option for us nor the AI. For some reason, if you use this feature you cannot edit anyones team color for that match, EVER AGAIN. Even if you go back to the main save lobby it will not allow you to alter their team colors. Removing the Random Civ variable prevents this from ever happening.

Since we have done all of this, we haven't had anymore issues with desync. Prior to this my buddy who was the "desyncer" tried updating his video driver, selecting DX11 and then back to DX12, verifying game integrity, uninstalling/reinstalling the game, obviously closing the game along with steam and reopening everything, and a few others I can't seem to remember.
Anyways, I hope this helps someone else as it has seemed to do the job for us.

Lastly, and most importantly:

I hope you all "Stand the Tests of Time", peace!

Thanks will try it out!

SOLUTION BELOW:

I had desync disconnections when playing multiplayer in all types of maps, with all kind of civilizations and in all stages of the game.

First, this seems to be a bug related to CPU/GPU/memory allocation. I could not detect what was causing it, but I noticed that it ALWAYS happened after the round was over ("moment please" message to the bottom right) and units were about to be mass moved accross the map, which seems to be when most of the CPU/GPU workload happens (obviously).

Knowing this, I tried almost all suggestions in this thread to attempt to lower workload with little to no success (lowering graphics, lowering resolution, setting the CPU priority for Civ.exe to High, playing on a freshly restarted PC, etc).

I always thought it was my old PC (4th gen i5 CPU, GTX 970, 24gb DDR3 memory) and that there was nothing to be done, but I was mistaken, as last night it happened to my brother who plays on an 8th gen i7 CPU with 32gb of RAM and a 2080ti.

We discovered that for some reason, if you are looking directly to the part of the map with a lot of units that are going to be mass moved when the round is over (aka the middle of your civilization or an area at war), the desync happens and you get kicked to the loading screen. Every single turn.

The SOLUTION? Look somewhere else. Really, look at the ocean or parts of the map not discovered yet, so the animation of dozens of units moving at the same time does not happen in front of your eyes.
The bad part? You might miss something if you don't pay extra attention at what was moved and where, but I certainly went from desyncing to playing indefinitely with no problems.

Picked up the game after 6 months and tried to play with my dad.

MP is now much worse, unplayable, constant desyncs, every single turn. Im not even joking.

In the past it was desync about every 20-50 turns, annoying but tolerable, restart and continue play, but this ....... completely unplayable atm.

Isnt this supposed to be a big gaming company whos kinda beyond small technical issues like this?

But.. we get dsyncs sometimes on turn 4 even... makes no sense.

its beyond me there is zero communications at all over MP, its completely ignored.

We've had desync many games.. always actually.. every single game it happens.

The solution is from another thread - disable some stuff on your network card and then desync is gone permanently.

I can't remember exactly the setting that's critical, but below you may wanna try as these are right now my non-defaults from windows default settings:

I disabled the jumbo
disabled IPv6
disabled the Large Send Offload IPv4 (I believe this was the critical setting to prevent desync errors)

After installing "Rice and Fall" and "Gathering Storm" we with my wife always have this problem with the Desync. Every fricking turn...

There was not any such problem before. Any thoughts? Any response from developers? We bought two DLC for two computers just to play together in local network and now we literally can't play.

Developers seems unresponsive to the issue, nothing is being done. Wish i knew how to get in touch but. alas

Same issues, deysnc on MP and regular crashes in SP... its the number1 topic in MP lobbies, always someone crashing, leaving, desync, lagg w/e 8 man FFA always ends up as a 4man game or so.
Seriously why or how has nothing been done or tried?

[Jin Shepard]

Just tried it again, turn 15, dc dc dc dc dc , turn 17 crash. This game..

Hi all,

Something that worked on our games to a degree is the host computer forcing the game to use less CPU threads than any other computer in the game. This seems to work reliably in the early game, but the issue can sometimes still pop up later in the game, when slower, older CPUs just can't perform reliably.

Credit and Reference for changing CPU thread usage parameters in this thread:
https://www.reddit.com/r/civ/comments/hcu9cv/civ_vi_improving_loading_times/

I have a six core, 12 thread CPU, and limiting it down to 8 threads got us to turn 45 without any desynching. Then issues started appearing, but we intend to experiment with how low the thread count can go before the game becomes unplayable. It seems like Civ makes very good use of all cores, so it's really important to talk to your friends and actually figure out who has the least cores, are they hyper threaded, speeds, etc...
