Octane
by pozii
Octane is a Fabric optimization core for Minecraft 1.20.1 that reduces background work during play and loading.
What it does
Octane targets wasted work in the game loop, trimming particle and sound floods before they reach the renderer, and caching recipes, models, blockstates and splash textures so they are reused on reload instead of rebuilt. The aim is smoother play with less memory churn over longer sessions.
The mod ships a built-in report that writes boot markers and tick timings, so a player can see where loading time goes. It is meant to be dropped into a mods folder without setup or config, and it makes no gameplay changes. Fabric API is required, and Octane is client and server, so the server and every player run the same two jars.
Files target Minecraft 1.20.1 only. The latest Fabric build is v0.3.1-mc1.20.1, published on 2026-09-05, after the first release on 2026-09-04. The code is open source under the Apache License 2.0, with public source code and an issue tracker.

Use cases
Modpacks
Packs that already include Sodium, Lithium and FerriteCore can add Octane alongside them for a leaner background load.
Slow starts
Players who want to see where their startup time goes can read the boot markers the report writes.
Who it’s for: Players who run Fabric 1.20.1 modpacks and want less background overhead, and server owners who want the same core on both sides without extra setup.

What the author says
Octane is a lightweight optimization core for Minecraft. Drop it into your mods folder — no setup, no config, no gameplay changes. It works with Sodium and Lithium, not against them. Servers: same two jars into the server's mods folder, restart. Done — players don't need to install anything extra.
