Vodium

Vodium bundles optimizations for rendering, physics, chunk systems and entity loading into a single mod. Its author describes it as a replacement for numerous optimization mods, so a player who would otherwise install a stack of them can use Vodium alone. The author notes that it does not conflict with the mods it replaces, and that players do not need to install a bunch of separate optimization mods alongside it. Fabric API is required.

Among its options, Vodium can disable the built-in entity physics and AI optimization, which overlaps with Lithium, and disable entity culling, which overlaps with EntityCulling. It can also disable region batching when Iris Shaders is in use. The author reports testing with C2ME and says the mod is not too large to replace the mods it covers. Vodium can be switched off with a command and back on with another, which the author used during testing. The mod runs on the client or on the server, and either side can run it alone.

Vodium includes its own shader system, which the author describes as still in progress and not yet a complete replacement for Iris. Basic effects and shaders work, and the author states the feature is already usable. Shader packs are obtained separately and placed in the shaderpacks folder. Files are published for 1.20.1, 1.20.4 and 1.21.1, with 0.8.6+1.21.1 as the latest Fabric file for 1.21.1.
