Zagga Zach's Ultra Performance Modpack

by Zagga_Zach · on Modrinth

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Fabric only.

Minecraft 1.21–1.21.4Newest
Minecraft 1.20.4

⬇ Download for 1.21–1.21.4 ⬇ Download for 1.20.4

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
