Valheim Optimizer
Version: 2.1.0
Author: ChangosOF
A comprehensive performance optimizer for Valheim, featuring:
- Adaptive GC Sweeps
Runs GC.Collect() & UnloadUnusedAssets() when frame time is under your MaxFrameTime.
- Dynamic LOD & Texture Quality
Automatically adjusts QualitySettings.lodBias and masterTextureLimit based on frame time.
- Zone Prefetching
Predictively loads world zones ahead of fast‑moving players to smooth travel.
- Prefab Pooling & Impostors
Pools heavy prefabs (fires, trolls, benches, explosive arrows) and adds LODGroup impostors.
- Gradual Mob Despawn
Server‑only, drip‑despawns up to 2 distant mobs per tick to reduce CPU & network load.
- JIT Warm‑Up
Prepares hot methods on startup to avoid hitches.
- Multiplayer Safe
All despawn logic runs only on the server to prevent client desyncs.
- More stability making mobs despawn 2 mobs/tick for less stutter

Configuration
On first run a config file is generated at:
Install & use Install: BepInEx plugin
- The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
- Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
- Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
- Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.
Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file. In multiplayer, the host and every client need the same mods installed.
Install these first, or the mod will not work:
