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 1.21–1.21.1Newest
Minecraft 1.20.5–1.20.6
Minecraft 1.20.4
Minecraft 1.20–1.20.1
Minecraft 1.19.4

⬇ Download for 1.21–1.21.1 ⬇ Download for 1.20.5–1.20.6 ⬇ Download for 1.20.4 ⬇ Download for 1.20–1.20.1 ⬇ Download for 1.19.4

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.

PacketDiscard

PacketDiscard is a server-side mod that discards (doesn't send) 50% of packets the server tries to send, except for the essential ones like login packets, Chunk load packets and keep-alive packets.

Thanks to YTG1234 for PacketIgnore, the mod that inspired me to make this one.
