Our notes on Rapid Optimization

What sets it apart

Rapid Optimization is a performance-only pack that claims more speed than other optimization packs. The author argues rival packs include unneeded mods that cost frames, so this one holds only optimizers.

The page publishes its own performance percentages and a one-scene FPS comparison against vanilla and Fabulously Optimized. No hardware, settings beyond a render distance, or repeatable method is given, so this note does not repeat the figures.

The latest mod list includes Sodium, Lithium, ModernFix, ImmediatelyFast, Entity Culling, More Culling, ScalableLux and Iris.

Who it suits

Players on weak machines, or anyone chasing frame rates across many versions. Coverage runs from 1.7.10 and 1.8.9 through 1.12.2, 1.16.5, 1.18.2, 1.19.2, 1.20.1 and the 1.21 and 26.x lines, on Fabric, Forge and NeoForge.

Before you install

The author recommends 26.2 on Fabric, 1.21.1 on NeoForge and 1.20.1 on Forge for best results.

For the oldest versions, the pack does not bundle OptiFine for licensing reasons. You must download it from the official site and place it in your mods folder.

The page lists known conflicts and fixes. Starlight and ScalableLux clash with Create versions above 0.5.1j. ImmediatelyFast may hurt some devices, with a config option to turn off. Ixeris above 1.20.1 may cause black screens or drops with shaders. Accelerated Rendering can distort third-person models with some shaders.

Foliage defaults to Fast, so switch it to Fancy if leaves look wrong with shaders.

No RAM figure is published. The license is MIT.

Playing with friends

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