Multiplayer Basically Unplayable

[Mythos]

Trying to play this with a buddy of mine, but every 3 turns or so, the game desyncs. We both have good internet (gigabit) with no packet loss. We both try to wait until we can "end turn" at the same time, without doing anything when we are both ready. I've tried basically every solution I've found online so far. Maybe port forwarding would help? I'm kind of at a loss at this point, we might have to stick to stellaris for co-op.

It's really frustrating because this is such a unique and fun game to play together. If anyone has some suggestions that maybe I've missed or success playing this let me know. I hope the developers do something about trying to patch the netcode.

edit: Vanilla game btw with 3 addons enabled (except hacking).

Have you installed the beta patch?

Where do I go about finding that and which version is that? All I see is old versions and patchpreview.

Does it specifically address multiplayer desync issues?

[Bozobub]

The patchpreview was/is the beta patch, altho that may be released now? Not really sure. But I do know it was supposed to address at least some multiplayer issues.

Worth a shot, thanks.

Are there any other settings that seem to help? Like does turning on vsync or turning the graphics down have an impact? I have a pretty modern computer with a 3080 gtx ti and a 12700k cpu.

Are there patchnotes somewhere for the previewpatch? Can't seem to find any.

The top pinned post is about their latest beta hotfix they released in July that's supposed to help with the de-syncs:

The beta has gone live months ago

Desincs happen when your game is running differently than other players, you both need to verify your files and make sure you're playing with the same mods.
If that doesn't work try uninstaling and also deleting the stuff steam doesn't uninstal. (Exept your saves of course)

I checked their website forums, community news, news on their website but missed the pinned post in general haha. Thanks!

Ya, I was surprised it wasn't in the news tab.

No mods and it's a fresh install. Good tip about checking the folder for some mods left over though. At one point I did run the game with mods. It's clear though. Thanks for trying to help out.

In the settings of Steam Library there is an item “Change download region”, maybe it is necessary to select the nearest identical ones? Have you purchased a static IP address?

...Has anyone tried running it as a LAN game over Hamachi, or any other (free) "pseudo-LAN" client? I don't "do" multiplayer in general, but I feel this might be a workaround.

I'm going to post this in case someone searches this thread at some point, but I managed to fix the desyncs. I noticed I had a launch command line for force opengl way back when it used to help with space battle performance and sound cut out. I also installed the beta patch. I'm not sure which of the two fixed the problem, but I'm willing to bet the opengl force was causing the desyncs.

There's also a fix on prepatch about pirate lair destruction causing desync.
