Plutonium
A modpack focused on maximizing performance, fixing bugs, and improving stability to deliver the best possible Minecraft experience. Up to 10X FPS improvement.
Quick answer
Which Plutonium release matches Forge?
Plutonium 5.1.2 - 1.12.2 LTS is a complete pack release for 1.12.2 with Forge 14.23.5.2864. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 18 mods in this pack file.
Pack setup
How should I set up Plutonium for players and a server?
Use Plutonium 5.1.2 - 1.12.2 LTS as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.
A pack is a matched client and server setup, not one mod with an install-side label. Keep its release, loader, manifest and overrides together.
These numbers come from the pack file you chose. “Not labelled” means we don’t know which side it belongs on—not that it is safe everywhere. The file count is not a RAM estimate.
What are the server requirements for Plutonium?
Plutonium 5.1.2 - 1.12.2 LTS on Forge. The pack contents and setup notes below stay tied to that release.
The selected pack release is Plutonium 5.1.2 - 1.12.2 LTS. That file is for Minecraft 1.12.2 with Forge 14.23.5.2864. It contains 18 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod. A file count cannot tell us the right RAM, CPU or storage; size the server for the players and world you actually run.

Systems compatibility
Plutonium supports Linux,Windows,MacOS and FreeBSD.
All editions are being tested on the following operating systems before officially releasing them:
⚠️ The rolling release edition is only tested under Arch Linux against critical bugs
ℹ️ All releases are being tested on the latest versions of the listed operating systems and on real hardware (We are not using VMs for testing)
ℹ️ Apart from manually testing each edition on all listed operating systems, we also run an automated stress-testing script on each platform to ensure stability. This process includes repeatedly generating worlds with different seeds and terrain layouts, mass-deleting maps, loading each generated world under different rendering settings, and checking for performance regressions or log errors.

📦Explaining the flavours
Stable
Choose Plutonium – Stable for a reliable, well-tested, and highly compatible experience.
This edition prioritizes stability, performance, and broad mod compatibility, making it ideal for long-term gameplay and general use.
Performance may vary depending on your hardware and operating system.
Rolling Release/Unstable
Choose Plutonium – Rolling Release (Unstable) if you want early access to the latest features, updates, and optimization improvements before they are included in the Stable edition.
This edition is tested primarily for critical issues (such as crashes) but may contain bugs or instability.
It is recommended for testing, benchmarking, and advanced users, rather than long-term worlds.
Vulkan Edition
Choose Plutonium – Vulkan Edition for maximum performance and reduced CPU overhead through the use of a Vulkan-based rendering pipeline.
This edition may deliver significantly improved performance on supported hardware, but sacrifices compatibility with many mods, as Vulkan currently has more limited ecosystem support compared to the standard Sodium-based renderer.
Due to its minimal and focused mod stack, this edition is often the most stable in terms of internal consistency.
1.12.2-LTS
Choose Plutonium – 1.12.2 LTS (Long-Term Support) for an optimized and modernized experience on Minecraft 1.12.2.
This edition includes:
- performance improvements and bug fixes tailored for 1.12.2
- support for modern Java versions via Cleanroom
- improved compatibility with newer hardware and systems
Stability and performance may vary depending on your hardware and operating system.
