If you start a Valheim server directly in the game, keep in mind that you run not only this server, but also the game itself (as well as the operating system) on your PC. Your computer must be able to not only handle the server, but also meet the requirements of the game. In addition, your Internet connection is critical in the stability of the server set up. Even very powerful connections will reach their limits if there are more than three players on the server.
For the hosting of Valheim’s dedicated server software, there is no official information from the manufacturer’s side so far. Since the graphical design of the survival game - at least in the Early Access status - was deliberately kept simple, Valheim is by no means particularly resource demanding. However, technical information from players suggests that less powerful setups are less suitable for hosting the game world in the long run. The more intensively players interact with the world, for example by constructing buildings or entering dungeons, the more volatile Valheim servers with little RAM and CPU have been. The same is true when the number of simultaneously active players increases.
Below we have summarised the most important system requirements of a Valheim server for you.
