Frequently asked

Does Swiftly Optimized (Forge & fabric) work on Minecraft 1.21.11?

Yes. 1.21.11 is the newest Minecraft version Swiftly Optimized (Forge & fabric) 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 Swiftly Optimized (Forge & fabric) support?

Everything the author has declared, from 1.7.10 up to 1.21.11. The full list is in the table above, with the Java runtime each version needs next to it.

Which loader does Swiftly Optimized (Forge & fabric) need?

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

Which Java version do I need for Swiftly Optimized (Forge & fabric)?

Java 21 or newer, because that is what the newest Minecraft release it supports requires. The requirement comes from the game rather than from the modpack itself.

How do I install Swiftly Optimized (Forge & fabric)?

Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the modpack and Minecraft all have to be on the same version, which is the usual reason a mod does not appear in game.

Where do I download Swiftly Optimized (Forge & fabric) safely?

From the author's own page on CurseForge, which is where the data here is synced from. MCReference never mirrors, re-hosts or repackages a file: every download button points at the original source, so you get exactly what the author published.
