Graphene

📖 Overview

Graphene is a powerful, free and open-source performance mod for Minecraft 1.19.4 and above. It fixes a handful of vanilla bugs and boosts frame-rate, startup speed and server tick-time while remaining highly configurable and compatible with almost everything else in your mod folder.
Whether you run a light client pack or a 400-mod kitchen-sink, Graphene usually “just works” and the gains are especially visible on crowded servers.

👀 What Graphene Does

Performance

• Distant-tile suspension – entities and TEs far away from players stop ticking, but bullets (TaCZ), the Ender Dragon, etc. are protected from freezing.
• Faster client bootstrap – shave seconds off launch.
• Background throttling – optional mode that lowers FPS and chunk updates when the window is out-of-focus; instantly restores on return.
• Quicker world-gen – compatible with other chunk-acceleration mods.
• Light-engine tweaks – reduce lighting recalculations.

Rendering

• Leaf culling (NeoForge ≤ 1.21.1 only).
• Static chest models – chests are batched and skipped at long range (configurable distance).
• Reflex – lowers render latency.

Game-play fixes & tweaks

• Boats no longer break or deal fall damage from any height (vanilla bug fix).
• Ground-item merger – faster, configurable replacement for Stxck.
• Bamboo light checks suppressed.
• Language changes apply instantly; no resource-pack reload.
• Several memory-leak patches ported from standalone mods.

🐛 Reporting Issues

Open an issue on the official Graphene repo (link at the top of this page).
Before you post:

1. Update to the latest build.
2. Try reproducing with default config – a few aggressive opts are off by default.
3. Attach the crash-log or latest.log.

❓ FAQ

Where is the newest file?
Head to the Modrinth project page – every approved build is there.

Can I ship it in my pack?
Yes. Graphene is MIT-licensed; redistribute freely.

Version support policy?
We target the platforms that need optimisation most first, then the widest-used versions, then the rest when time allows.

🙋 My game crashed

Do these checks before blaming Graphene:

1. Run Graphene alone – still crash?
2. Revert any config changes you made – fixed?
3. Suspect a mod conflict? Load only Graphene + the suspected mod in a clean instance.

If the crash survives the steps above, open a GitHub issue with logs attached.

⚠️ Attention!

Both Graphene and EntityCulling use LogisticsCraft/OcclusionCulling to implement similar features, which may cause conflicts!

❓ Something feels off?

Graphene is built for the average player, not for one specific setup. Every optimisation can be toggled in config/graphene.toml. If a feature breaks your pack or feels wrong, just switch it off – the rest will still help.
