ValhallaPerformance

All-in-one performance optimizer for Valheim with twelve modular systems for smoke, lights, culling, pieces, memory, networking, rendering, streaming, VFX, tar pit cleanup, boot optimization, and log filtering.

This mod is in beta. I am actively testing features and fixing issues. Please email feedback to: rare-relic-keg@duck.com

Inspired by these mods:

• []ValheimPerformanceOverhaul (Skarif)

  []Smoke_Collision (JereKuusela)

  []VBNetTweaks (VitByr)

• []Potato

  []Medium

• []Profiles are selected in config under 1. Profile.

  []Profiles apply client-side visual/performance baselines only.

  []Network tuning is profile-independent. Profiles never override network settings.

  []Zstd package compression is enabled by baseline for all profiles.

  []Potato is intentionally extreme and meant as a last-resort FPS mode.

  []Max keeps smoke and light distances close to vanilla with minimal smoke/light culling.

  []Advanced users can still edit all individual config entries.

  []Profile values apply during config init when the selected profile changes, not every frame.

SystemsBoot OptimizerSkips logo intro flow with safe one-time bypass hooks and pre-compiles critical methods using incremental, time-sliced warmup to reduce first-use JIT hitching without one-frame bursts.

Smoke System (replaces Smoke_Collision + VPO smoke)Uses lightweight upward drift physics with roof collision spherecasts, per-source caps, and distance culling. Keeps smoke behavior while reducing CPU cost.

Light SystemUses distance-based light culling with hysteresis to prevent cull-edge on/off flicker (including aggressive presets like Potato). Shadow casting is budgeted separately by proximity, and optional flicker freeze reduces per-frame shadow map churn in large bases.

Culling SystemIncludes AI throttling plus distant animation throttling. Also supports far skinned-mesh reduction and optional far ragdoll sleep to reduce CPU overhead in dense scenes.

Piece OptimizerMaintains support caching and adds dirty-region processing so support work is focused near changed pieces instead of broad checks.

Memory SystemPerforms GC on natural pauses, monitors heap pressure, and runs safe asset cleanup intervals.

Network System (replaces VBNetTweaks)Adds adaptive network control (ping/loss aware sync c
