FusOpt

A small open-source mod for when Fusion lobbies fill up with people and props and your FPS falls apart. Settings live in BoneMenu and stick between sessions.

A normal messy VR desk — Not a render farm. Just a desk that has seen too many 20-player lobbies.

What it does

Culls distant prop renderers on your client so the GPU stops drawing junk across the map.
Puts far rigidbodies to sleep when they are not moving.
Cuts particles and shadows at range, and can adapt quality to your FPS.
If you are the host: optional DespawnAll cleanup on a timer or prop threshold.
Everything is toggled from BoneMenu and saved via MelonPreferences.

Presets

Start with Crowded if the lobby is already a mess.

Near detail: 16 m
Far cull: 48 m
Prop budget: 70

Quick notes

Client culling only changes what you render. Host cleanup wipes networked props for everyone — keep Auto Clean off unless you mean it. MIT license.
