ValheimScalability

ValheimScalability

ValheimScalability is a client-side performance mod for Valheim focused on

improving rendering performance in large builds, dense settlements, and heavily

populated world areas.

The mod reduces the number of individual objects that need to be rendered by

grouping compatible static meshes into larger render batches. It includes

safeguards for animated, interactive, destructible, modded, physics-driven, and

wind-affected objects so they can remain independent when needed.

Let Valheim render more without requiring players to build less.

Features

Sector Mesh Clustering

ValheimScalability groups compatible static meshes within loaded world sectors

into larger combined meshes.

This can significantly reduce renderer and draw-call overhead in areas

containing large numbers of:

• Building pieces
• Walls
• Floors
• Roof pieces
• Static decorations
• Rocks and other compatible world geometry
• Other static meshes added by mods

Original gameplay objects remain loaded and functional. ValheimScalability

changes how compatible geometry is rendered; it does not remove the underlying

Piece, WearNTear, ZNetView, physics, collider, or other gameplay

components.

Adaptive Rendering

In Adaptive mode, distant cells use clustered rendering while nearby visible

cells return to their original renderers.

This provides a compatibility-oriented balance between normal interaction and

lower draw-call overhead.

Full Cluster Rendering

FullCluster keeps compatible geometry clustered regardless of player distance.

This generally provides the strongest draw-call reduction and is especially

useful for benchmarking and extremely large builds.

Easy A/B Performance Testing

Set:

Mode = Off

to restore normal object rendering without uninstalling the mod.

This makes it easy to compare the same location with clustering enabled and

disabled.

Rendering Modes

| Mode | Behavior | Recommended Use |

|---------------|----------------------------------------------------------------------------------------------|-----------------------------------------------------------|

| Off | Original Valheim renderers only. Generated cluster rendering is not presented or rebuilt. | Baseline FPS comparisons, troubleshooting |

| Adaptive | Nearby visible cells use originals; farther cells use clustered rendering. | General gameplay |

| FullCluster | Uses clustered rendering everywhere it is safe; player proximity does not restore originals. | Maximum performance, very large settlements, benchmarking |

Installation

Install ValheimScalability like a normal BepInEx Valheim mod.

Mod Manager

Install the mod through your preferred -compatible mod manager.

Manual Installation

Copy the ValheimScalability plugin into your Valheim BepInEx plugins directory:

Valheim/

└── BepInEx/

└── plugins/

└── ValheimScalability/

Launch the game once to generate the configuration file under:

BepInEx/config/

Client-Side Mod

ValheimScalability is a client-side rendering optimization.

It does not change:

• World data
• Building placement
• Damage values
• Networking ownership
• Saved objects
• Server-authoritative gameplay state

Dedicated servers do not need to run the rendering system. Each player can

configure the rendering behavior for their own client.

Recommended Profiles

| Profile | Mode | Cell Divisions | Lowest LOD | MaterialPropertyBlocks | Notes |

|---------------------|---------------|---------------:|------------|------------------------|--------------------------------------------------------|

| General gameplay | Adaptive | 1 | true | Skip | Recommended starting point |

| Maximum performance | FullCluster | 1 | false | Skip | Strongest batching and easiest benchmark configuration |

| Baseline / disabled | Off | 1 | N/A | N/A | Compare against normal rendering |

CellDivisionsPerSector = 1 is the default because it produced the strongest

real-world gains during testing. Higher values trade batching efficiency for

finer Adaptive-mode p
