Embeddium

Embeddium is a free and open-source performance mod for Minecraft clients. It is based on the last FOSS-licensed version of the Sodium codebase, and includes additional bugfixes & features for better mod compatibility.

Despite being forked from Sodium, Embeddium is not supported by CaffeineMC. Do not report issues encountered with it to their bug tracker or in their Discord.

Highlights

All performance improvements from Sodium 0.5.8 and earlier, i.e. a rewritten terrain renderer, various optimizations to the immediate-mode rendering pipeline (used by entities, GUIs, block entities, etc.), and other miscellaneous improvements
Available for Minecraft Forge on 1.20.1 and older, Fabric on 1.20.1-1.20.6, and NeoForge on 1.20.1 and newer
Integrated Fabric Rendering API support (Indium is no longer required, and will not work with Embeddium)
Frequent patch updates to fix mod compatibility issues soon after being reported & reproduced
Additional APIs for mod integration
Optional support for translucency sorting (can be enabled in Video Settings)

For developers
