Our notes on Optimization

What sets it apart

Optimization is a performance-only pack. The project page says it consists only of well-chosen optimization mods, with no unnecessary ones. The listed selling points are maximum performance, fast updates and pre-configured settings.

The standout feature is how many Minecraft versions it covers. The page lists 1.12.2, 1.16.5, 1.17.1, 1.18.2, 1.19.2, 1.19.4, the 1.20 and 1.21 lines and the 26.x line up to 26.3, across Fabric, Forge and NeoForge. Builds on Modrinth are named after the renderer they use: Sodium on Fabric, NeoSodium on NeoForge, Embeddium on Forge, Celeritas for 1.12.2 and Vulkan for one 26.1.2 build. The page names Sodium, Vulkan, Embeddium and Celeritas as its selection. The newest Fabric builds were published on November 11, 2026.

The latest build’s mod list is short: Sodium, Lithium, FerriteCore, ModernFix, ImmediatelyFast, Entity Culling, More Culling and a few others. The page gives no benchmarks for its performance claims.

Who it suits

Players who want a quick, maintained performance setup on almost any Minecraft version, including older ones that other packs have dropped.

It will not suit anyone wanting shaders, since Iris is not in the latest mod list, or any added gameplay.

Before you install

The page recommends Eclipse Temurin 25 and suggests two Java flags: -XX:+UseZGC and -XX:+UseCompactObjectHeaders. It links to a third-party article about launch flags. These are the author’s suggestions, not requirements.

Install through the Modrinth App or a launcher that supports Modrinth packs, such as Prism. For the official launcher, the page links a converter that turns the pack file into a zip.

Modrinth shows 1,514 published versions, so pick the one matching your Minecraft version and loader carefully. No RAM figure is published.

Playing with friends

The pack is marked client-side only, and server support is listed as unsupported. No server pack is published, and none is described on the page. Which servers accept the mods is not documented.
