Multiplayer Co-op Lag, Freeze, Latency: Call it What You Will

[Erik]

I can't find much information regarding the issue. While I did come across some posts about it, they dated back to 2020.

Our main problem is that the game is becoming increasingly unresponsive or "laggy", to use an informal term.

Examples:

• Opening a chest or a corpse can take up to 20 seconds during which the character simply stands there, and nothing happens.
  
• Transferring items within the inventory behaves similarly to opening a chest, taking between 5 to 20 seconds before any movement occurs.
  
• Using the jump action seems to nearly crash the game; the desynchronization is so extreme, it's almost laughable.

Is anyone else encountering these issues? We experience them with 2 and 3-player sessions, but in single-player mode, the game runs smoothly.

Troubleshooting steps we've taken:

• Configured the router firewall for port forwarding.
  
• Allowed all related accesses in Windows firewall for "Baldur's Gate 3".
  
• Deleted save games and the Larian folder from %Appdata%.
  
• Uninstalled and reinstalled the game.
  
• Tried using DX11 and Vulkan.
  
• Tested various in-game settings.
  
• Disabled cross-save (though I believe it was disabled by default).
  
• Turned off Steam cloud save.

We're running out of solutions to try, so any suggestions that could help resolve this would be greatly appreciated.


To clarify, I absolutely love the game and would rate it a solid 13/10. I have no complaints about its content. I just wish I could play without a 20-second delay between giving a move order and executing an attack.

My PC specs:

• Operating System: Windows 11 Pro 64-bit (10.0, Build 22621) (22621.ni_release.220506-1250)
  
• Processor: 13th Gen Intel(R) Core(TM) i9-13900K (32 CPUs), ~3.0GHz
  
• Memory: 65536MB RAM
  
• GPU: NVIDIA GeForce RTX 4090

Also noticing this with 3 player sessions. Although as a host it's more just stutters when they are in dialog or are far away in the game. From the people that join they see a slight lag on performing actions. Hoping for a fix though

Probably has to do with latency or general connection between everyone. I've only noticed it when my or a friends internet struggles for a moment.
