Radium

Radium is a fork of Sodium, a rendering optimization mod for the Minecraft client which focuses on reducing microstutter and improving frame rates, made to have compatibility with 1.8.9

Radium is a powerful rendering engine and optimization mod for the Minecraft client which improves frame rates and reduces micro-stutter, while fixing many graphical issues in Minecraft.

Sodium is the result of thousands of hours of development, and is made possible thanks to players like you. If you would like to show a token of your appreciation for CaffeineMC's work, and help support the development of Sodium in the process, then consider donating to CaffeineMC.

Nightly builds (for developers)

We also provide bleeding-edge builds ("nightlies") which are useful for testing the very latest changes before they're packaged into a release. These builds are only provided for other mod developers and users with expert skills, and do not come with any support or warranty. It is often the case they have issues and lack compatibility with other mods.

The latest nightly build for each current branch of development can be downloaded below.

🔮 Forge Support

Currently, Radium does not support Forge, and it is likely that will remain the case for some time. Legacy Fabric is a much more lightweight and performant mod loader, and we recommend you use it.

To get the latest updates on this matter, please join our official Discord server.

🙇 Getting Help

For technical support (including help with mod installation problems and game crashes), please use our official Discord server. Do NOT ask for support in the CaffeineMC discord server.

📬 Reporting Issues

If you do not need technical support and would like to report an issue (bug, crash, etc.) or otherwise request changes (for mod compatibility, new features, etc.), then we encourage you to open an issue on the project issue tracker.

Please note that while the issue tracker is open to feature requests, development is primarily focused on improving compatibility, performance, and finishing any unimplemented features necessary for parity with the vanilla renderer.

Please do not report issues in the sodium repository

✅ Hardware Compatibility

We only provide official support for graphics cards which have up-to-date drivers that are compatible with OpenGL 4.5 or newer. Most graphics cards released in the past 12 years will meet these requirements, including the following:

• AMD Radeon HD 7000 Series (GCN 1) or newer
• NVIDIA GeForce 400 Series (Fermi) or newer
• Intel HD Graphics 500 Series (Skylake) or newer

Nearly all graphics cards that are already compatible with Minecraft (which requires OpenGL 3.3) should also work with Sodium. But our team cannot ensure compatibility or provide support for older graphics cards, and they may not work with future versions of Sodium.

OpenGL Compatibility Layers

Devices which need to use OpenGL translation layers (such as GL4ES, ANGLE, etc) are not supported and will very likely not work with Radium. These translation layers do not implement required functionality and they suffer from underlying driver bugs which cannot be worked around.

🛠️ Building from sources

Radium uses the Gradle build tool and can be built with the gradle build command. The build artifacts (production binaries and their source bundles) can be found in the build/mods directory.

The Gradle wrapper is provided for ease of use and will automatically download and install the appropriate version of Gradle for the project build. To use the Gradle wrapper, substitute gradle in build commands with ./gradlew.bat (Windows) or ./gradlew (macOS and Linux).

Build Requirements

• OpenJDK 17
  • We recommend using the Eclipse Temurin distribution as it's regularly tested by our developers and known to be of high quality.
  • Gradle 8.10.x
    • Typically, newer versions of Gradle will work without issues, but the build script is only tested against the version used by the wrapper script.
