Desync issues on FAF and base game

[DaBloodyBean]

Top game file is mine and the bottom game file is my buddies both from the same match.

Does it happen even without any mods and without any AI?
Have you both verified the game files via Steam/GOG ?

Beans log contains "warning: SND: XACT3DApply failed.", which I doubt is causing the desync, but it will cause issues long-term by randomly crashing.

It does happen without mods and without AI. It seems to happen every time I try to play with my buddies.

Does it happen with any other player as well, or just with your buddy?

[DaBloodyBean]

I also tried running with the launch options: "%s" /nomovie /D3D9

^ these are more recent attempts to play with my buddies.

Loaded up base game and I joined a random match and it seemed fine so I don't know why its messed up with my buddies when we all did the same fixes at the same time.
I dont remember how to find the Logs for the base game

[magge]

Well, at least we can narrow the issue down to your buddy, when you do not desync with other random players.

I am not sure what you mean by "base game".

• What CPU does your buddy have, and has he overclocked it by any chance?
• What security software is he using?

[DaBloodyBean]

"Base game" I'm referencing to steam version of Supreme Commander Forged Alliance without FAF. And its multiple friends not just one guy I'm desyncing with. even tried playing with one at a time on different matches and it still desyncs.

[DaBloodyBean]

Im pretty sure its on my end since most of the logs keep referencing an error running some lua scripts.

[magge]

Oh, when it is just the steam version, then the only solution I can suggest is to verify the files. A shot in the dark is, that the CPU may cause a desync when he you uses OC software - or when the CPU suffers from the Intel Core stability issues in 13th and 14th Gen Processors. Or his security software is interfering somehow.

Perhaps someone else has an idea how to approach just the steam version to find a cause of it.

[DaBloodyBean]

The screen most of the time when I desync.

I'll try to get his specs to compare when he has a chance but heres mine:
Processor Intel(R) Core(TM) i9-14900HX, 2200 Mhz, 24 Core(s), 32 Logical Processor(s)
Installed Physical Memory (RAM) 32.0 GB
OS Name Microsoft Windows 11 Pro

warning: Error running lua script: Attempting to lookup the RType for class Moho::CPlatoon before it is registered.

From "Bean's log" indicates that there's a CPU issue.

[DaBloodyBean]

How can i fix that or is that just a new pc kinda thing?

[Nomander]

Yeah you'll need a new CPU, I haven't read about anyone fixing it aside from replacing the CPU. Maybe intel can replace the CPU for you on warranty.

[DaBloodyBean]

Thats lame haven't had any issues on any other games with this besides this one

[DaBloodyBean]

I just don't get how I can play matchmaking fine just not FAF or with buddies

[Nomander]

Moho::CPlatoon is for AI platoons, so I guess your CPU is broken in such a way that only code for AIs cause issues.

[DaBloodyBean]

interesting, well thanks for the help at least but sucks that it's messed up in such a way that I can't fix it any other way

I can't tell whether it is a cpu issue, but I'd suggest to just reinstall the game completely for now, because there is something happening with game exe for sure.
