⚡ LiteCPU — Client-Side Performance Mod

A client-side Fabric performance mod focused on reducing render load, particle spam, and unnecessary visual overhead. Works on any server — no server installation required.

✨ What does LiteCPU do?

🎆 Particle Optimization

LiteCPU reduces particle overload in two ways:

• Limits particle spawning once too many particles are already active
• Optionally culls particles that are too far from the camera

This helps in situations like combat, mob grinders, explosions, and crowded servers where particle spam can tank FPS.

🧠 Adaptive Performance

LiteCPU can dynamically tighten visual budgets when your FPS drops, then relax them again when performance recovers.

It can automatically adjust:

• Particle limits
• Particle cull distance
• Entity render distance
• Block entity render distance
• Chunk update delay

This makes the mod more responsive than a static “always low” optimization setup.

🧟 Entity Render Culling

LiteCPU can skip rendering entities beyond a configurable distance from the camera.

You can:

• Set a manual entity render distance
• Leave manual distance disabled and use automatic fallback distance culling instead
• Enable enhanced frustum culling for more aggressive off-screen entity skipping

📦 Block Entity Culling

LiteCPU can reduce rendering of distant block entities like:

• Chests
• Signs
• Furnaces
• Other tile/block entity renderers

This is especially useful in bases, storage rooms, and heavily decorated areas.

🎯 FPS Limiting

LiteCPU lowers FPS when full framerate usually isn’t needed:

• While menus or screens are open
• While the game window is unfocused

This reduces CPU/GPU usage and can lower temperatures and power draw when tabbed out.

🗺️ Chunk Update Throttling

LiteCPU can delay distant chunk mesh rebuilds to reduce CPU spikes from chunk updates and render rebuild spam.

This is most useful while moving around large areas or when lots of chunk updates happen at once.

🧩 Compatibility Awareness

LiteCPU includes compatibility checks for mods like VulkanMod and Particle Core.

If needed, it can automatically disable certain hooks to avoid conflicts, with optional override settings for advanced users.

📊 Performance Stats Logging

LiteCPU can periodically log performance-related stats, including:

• Current FPS
• Adaptive mode state
• Suppressed particles
• Culled entities
• Culled block entities
• Skipped chunk updates

🎛️ Configuration

Open Mod Menu and click the Config button next to LiteCPU to change settings in-game.

Current configurable categories include:

• Particles
• Adaptive Performance
• Compatibility
• Block Entities
• Entity Rendering
• FPS Limiting

• Statistics

📦 Installation

1. Install Fabric API
2. Drop lite-cpu.jar into your mods/ folder
3. (Optional) Install Mod Menu + Cloth Config for the in-game config screen

❓ FAQ

Does the server need this mod?
No. LiteCPU is fully client-side and works on any server.

Does it change gameplay?
No. LiteCPU only changes rendering and visual performance behavior on the client.

Is it compatible with other performance mods?
Generally yes. LiteCPU is designed to be lightweight and client-only, and includes some compatibility safeguards for known rendering-related mods.
