ValheimPerformanceOptimizations [H&H Compatible]

Rendering, logic, and loading time optimizations for both client and server versions of Valheim.

You can use the mod on either the server or the client, or both, it should work regardless.

Changes in 0.7.6

• Fixed conflict with SharedMap
• Fixed pickable objects sometimes not visually appearing as regrown
• Fixed camps never respawning enemies within them

Changes in 0.7.5

• Jotunn is no longer required to use the mod
• Fixed more EffectArea errors

Changes in 0.7.4

• Fixed crazy spawnrates
• Fixed being unable to breed animals
• ValheimRaft compatibility (at the cost of performance)
• Fix errors after logging out/quitting

Changes in 0.7.3

• Another attempt at fixing the roof checks

Changes in 0.7.2

• Fixed the 'Collection was modified' error
• Potential fix for leaking roofs

Changes in 0.7.1

• Fixed snow storm particles appearing inside buildings
• Fixed being unable to sleep
• Fixed other related AOE effects not working

New in 0.7.0

• Optimizations for structural integrity
• New object pooling system for build pieces - less lag when entering bases
• New smoke rendering solution - less lag rendering smoke puffs
• Snow storms no longer tank fps
• Fixed grass not appearing in the main menu
• Fixed objects spawning at 0 0

Rest of the changes can be found in CHANGELOG.md

Features

• New object pooling system for build pieces - less lag when entering bases
• New smoke rendering solution - less lag rendering smoke puffs
• Snow storms no longer tank fps
• Various optimizations for GPU rendering
• Multithreaded terrain loading
• Much faster loading times
• Various improvements to AI
• Optimizations for structural integrity

Stats

• 5-10 ms faster GPU render times in bases (3 fps without the mod -> 15 fps with)
• General game stability improvements - less stutters in bases
• 20+ seconds faster world loading times, especially for big worlds (excluding the first launch)
• Less stutters when loading new terrain
• General game logic performance improvements (no concrete data on framerates)

Configuration

The mod config is stored in the dev.ontrigger.vpo.cfg file.

Most optimizations done by the mod do not affect the gameplay in any way, however some of its optimizations might cause compatibility issues with other mods.

• Threaded terrain collision baking

  If enabled terrain is generated in parallel, this reduces lag spikes when moving through the world. If you see terrain disappear, please report it on github, disabling this option will likely fix the issue.

• Object pooling

  If enabled vegetation objects are taken from a pool, instead of creating and destroying them everytime. This greatly increases performance when generating new terrain. If you notice some objects becoming invisible, please report it on github, disabling this option will likely fix the issue.

  • Object pooling multiplier - this option does not do anything useful for now

Manually compiling the mod

In order to manually compile the source code of the mod, create a file called Environment.props inside the project base and change the Valheim install path to your location.

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="Current" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

    <!-- Needs to be your path to the base Valheim folder -->

    <!-- Optional, needs to be your path to a r2modmanPlus profile folder -->
