BetterNetworking Valheim

Now compatible with Mistlands!

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.

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.

Features

• crossplay enabled: improves compression speed by more than ~8000% (yes) and compression ratio by up to ~50%!
• crossplay disabled: adds network compression
• allows forcing crossplay (enabled by default)
• package queueing, changing network update speed, min/max send rates, queue size, and network buffer size in Steamworks (AKA crossplay disabled)
