Better Networking

Compatible with Valheim 0. 217. 28 and above!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.

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.
