MagiCorp Valheim Optimizer

Client and server performance optimisations for Valheim focused on reducing loading stalls, improving networking responsiveness, shortening portal transitions and avoiding unnecessary main-menu rendering work.

Included

• Faster join/loading path with asynchronous scene loading where Valheim supports it.
• Full-screen MagiCorp loading artwork instead of the bare pre-join text screen.
• Network send-window and compression optimisations with compatibility safeguards.
• Reduced distant-teleport minimum delay where safe.
• Optional minimal main menu to avoid unnecessary 3D world, camera and particle work.
• Built-in diagnostics and benchmark counters.

Install on clients for client/loading optimisations. Install on the server as well to use the matching network-side optimisations.

Configuration is generated at BepInEx/config/magicorp.valheim.optimizer.cfg.

Changelog

0.1.17

• Safety-disabled the experimental asynchronous remote scene loader after a client was observed negotiating successfully but never reaching character spawn.
• Remote joins now use Valheim's normal scene transition while retaining the optimizer's negotiated network, object-creation, spawn-delay and portal optimisations.
• Dedicated servers no longer apply the minimal-main-menu world-generator suppression.

0.1.16

• Expanded the Thunderstore documentation with loading-stage percentage improvements and benchmark context.
• Documented the server-side and all-peer requirements needed to enable the full optimisation path.
• No behavioural changes from 0.1.15.

0.1.15

• Added a dedicated Valheim Optimizer Thunderstore icon.

0.1.14

• Replaced the bare pre-join loading overlay with packaged full-screen MagiCorp artwork.
• Preloads the loading image once and releases it cleanly on plugin shutdown.
• Falls back to the previous black/text loading overlay if the artwork cannot be loaded.
• Expanded minimal-main-menu optimisation to suppress additional non-UI rendering work.
