FusOpt

Open-source Fusion lobby optimizer for BONELAB.

Big lobbies (20+ players) + prop spam = uneven FPS. FusOpt fixes your machine first, and gives hosts optional auto-clean tools.

What it does

Feature	Effect
Prop Cull	Hides distant clutter renderers locally
Rigidbody Sleep	Sleeps far props to cut physics
Particle / Shadow Cull	Pauses far FX, drops distant shadows
Adaptive Quality	Scales shadows & lights from FPS
Host Clean	DespawnAll + interval / threshold
BoneMenu	Full control, settings persist

Presets

• Balanced — everyday play
• Performance — solid FPS focus
• Crowded — 15–30 player lobbies (default)
• Extreme — survival mode for potato PCs / chaos servers

Install

1. MelonLoader + BoneLib + LabFusion
2. Install this package (or drop FusOpt.dll into Mods)
3. BoneMenu → FusOpt

Notes

• Client culling does not despawn networked props for others.
• Host cleanup requires you to be the Fusion host.
