What is the difference between a local and a dedicated server?

In Valheim, hosting and joining servers is a key part of the multiplayer experience, and understanding the difference between a local server and a dedicated server is crucial for smooth gameplay. A local server is hosted directly from your computer while you play the game. This means that the server runs on your machine, and other players can join your world as long as your game is running and your internet connection is stable. Local servers are ideal for small groups of friends or casual play sessions, as they are easy to set up and require no additional hardware or software.\n\nOn the other hand, a dedicated server is a separate instance of the game world that runs independently of any player''s computer. This type of server is hosted on a dedicated machine or a cloud service, allowing it to run 24/7 without requiring a player to be logged in. Dedicated servers are better suited for larger groups or communities that want to play together consistently, as they provide more stability and can handle more players simultaneously. However, setting up a dedicated server requires more technical knowledge and resources.\n\nTo host a local server, simply launch Valheim, select the ''Start Game'' option, and choose the world you want to play in. Make sure to check the ''Start Server'' box and set a password if you want to restrict access. Once the world loads, your friends can join by selecting ''Join Game'' and entering your IP address or using the Steam Friends list. Local servers are convenient but have limitations, such as being dependent on your computer''s performance and internet connection. If your computer lags or crashes, the server will go down, disrupting gameplay for everyone.\n\nFor a dedicated server, you need to download the Valheim Dedicated Server tool from Steam. This tool allows you to set up a server on a separate machine or a cloud service like AWS or Google Cloud. After installing the tool, configure the server settings by editing the ''start_headless_server.bat'' file, which includes setting the world name, password, and port. Once configured, run the server, and it will operate independently of your game client. Players can join by entering the server''s IP address and password. Dedicated servers are more reliable but require more effort to set up and maintain.\n\nOne common challenge with local servers is performance issues, especially if your computer is not powerful enough to handle both the game and the server. To mitigate this, close unnecessary background applications and lower in-game graphics settings. For dedicated servers, a common issue is port forwarding, which is necessary for players to connect. Ensure that your router is configured to forward the correct ports (default is 2456-2458) to the server''s IP address. If players still cannot connect, check your firewall settings and ensure the server is running correctly.\n\nIn terms of gameplay mechanics, both server types allow players to explore the same biomes, such as Meadows, Black Forest, and Plains, and engage in activities like building, crafting, and fighting bosses. However, dedicated servers offer a more persistent experience, as the world remains active even when no players are online. This is particularly useful for large-scale projects, such as building massive fortresses or farming resources over time. Local servers, while less persistent, are more accessible for quick play sessions with friends.\n\nPractical tips for choosing between local and dedicated servers include considering your group size and playstyle. If you are playing with a small group of friends and do not need the server to run 24/7, a local server is the easiest option. For larger groups or long-term projects, a dedicated server is worth the extra effort. Additionally, always back up your world files regularly, regardless of the server type, to prevent data loss in case of crashes or corruption.\n\nIn summary, local servers are simple to set up and ideal for casual play, while dedicated servers offer greater stability and persistence for larger groups. Understanding the differences and choosing the right option for your needs will enhance your Valheim multiplayer experience.
