This mod greatly improves multiplayer performance. If you find this mod works as advertised, please endorse it!

Default settings should be fine for most people.

Settings (simple)

  • If your lag is fixed, change nothing. You're good to go. Have fun!
  • If NPCs are skipping, reduce everyone's update rate to 75% and increase their queue size to 48 KB.
  • If a player is skipping, reduce their queue size to 32 KB. If they're already at 32 KB, reduce their update rate.
  • If your server bandwidth is fantastic, try increasing its queue size to 80 KB.

Settings (advanced)

  • Queue size increase: Sends more data, but deprioritizes "important" objects and can overload a player's internet.
  • Update rate reduction: Sends data less often; if a person's internet is overloaded, this adds a little bit of lag in exchange for getting rid of a lot of lag.
  • Queue size->32 KB / update rate->100%: up to 256 KB/s per player. [Default]
  • Queue size->80 KB / update rate->100%: up to 640 KB/s per player.
  • Queue size->32 KB / update rate->50%: up to 128 KB/s per player.

Useful information about Valheim

  • ALWAYS quit the game using the in-game menu (NOT Alt+F4, closing console, etc.) Doing otherwise can cause issues. This is a problem with vanilla Valheim.
  • The player who arrives in an area first is responsible for lag there. Ideally, the people with the best internet should be ahead of the pack or first through a portal, at least until Better Networking 3.0.
  • Valheim multiplayer performance appears to better with crossplay disabled.

Keep in mind

  • Compression only works between computers with Better Networking.
  • Likely incompatible with (and better than) other networking mods.
  • Dedicated servers will not apply changes until restarted.
  • You must use the join code or external IP when connecting to servers on the same network when using crossplay.


  • crossplay enabled: improves compression speed (55x faster) and compression ratio
  • crossplay disabled: adds network compression
  • new connection buffer (AKA "ZDO buffer", prevents data loss)
  • change outgoing queue size
  • change outgoing update rate
  • change min/max send rates in Steamworks (AKA crossplay disabled)
  • dedicated servers: ability to enable/disable crossplay through Better Networking
  • compatible with Linux
  • compatible with players not running the mod
