Frequently Asked Questions
My Valheim server is lagging, What to do?
A common misconception is that the game uses P2P network. It does not, all data is sent between client <-> server and never between clients. Game logic is distributed and ran on the game clients rather than on the server.
If player-A is alone in an area all creatures and objects will be controlled by that player and synced to the server. If player-B walks over to player-A, player-A will still control the game logic of most objects in that area. If, however, player-A leaves the area, player-B will take control of the objects and so on.
This system allows a lot of heavy physics to happen on the client-side and without overloading the server. It is however pretty sensitive to one player having a bad connection. If player-A is controlling the monsters in the area has high ping to the server then player-B will also notice this, even though player-B has a perfectly fine connection to the server.
As of patch 0.147.3 Dedicated servers now always use direct connections instead of using Steam Datagram Relay (SDR). This should result in much lower latency for most players.
