Frequently asked

Does Ultra Fast Optimization work on Minecraft 1.21.10?

Yes. 1.21.10 is the newest Minecraft version Ultra Fast Optimization declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.

Which Minecraft versions does Ultra Fast Optimization support?

Everything the author has declared, from 1.16.5 up to 1.21.10. The full list is in the table above, with the Java runtime each version needs next to it.

Which platform or loader does Ultra Fast Optimization support?

NeoForge, Forge, Fabric. A build for one platform or loader will not necessarily load on another, so this is the first thing to check before the Minecraft version.

Which Java version do I need for Ultra Fast Optimization?

On the newest Minecraft version it supports, Java 21 or newer. The requirement comes from the Minecraft version you run rather than from the modpack itself, so on an older supported Minecraft the answer is that version's Java, not this one.

What licence is Ultra Fast Optimization under?

CC0-1.0, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.

How do I install Ultra Fast Optimization?

Use a launcher that imports packs, such as Prism Launcher, the Modrinth App or the CurseForge app, and open the pack file with it. The launcher installs the right loader and mods for you; installing a pack's mods by hand is the error-prone way.

Where do I download Ultra Fast Optimization safely?

Start with the author's page on Modrinth, which is where the data here is synced from. MCReference does not host or repackage files. The download link goes to the source recorded for that release; verify the publisher, filename and checksum before running it.
