TT20 (TPS Fixer)

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

Mod loader

Minecraft version

⬇ Download for 26.1–26.2 · Fabric⬇ Download for 1.21.11 · Fabric⬇ Download for 1.21.9–1.21.10 · Fabric⬇ Download for 1.21.4–1.21.8 · Fabric⬇ Download for 26.1–26.2 · NeoForge⬇ Download for 1.21.11 · NeoForge⬇ Download for 1.21.9–1.21.10 · NeoForge⬇ Download for 1.21.4–1.21.8 · NeoForge⬇ Download for 26.1–26.2 · Quilt⬇ Download for 1.21.11 · Quilt⬇ Download for 1.21.9–1.21.10 · Quilt⬇ Download for 1.21.4–1.21.8 · Quilt⬇ Download for 1.21.5–1.21.8 · Forge
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.

TT20

TT20 helps reduce lag by optimizing how ticks work when the server's TPS is low.

Regarding singleplayer

Singleplayer should work fine! You can use the mod on the client without problems.

🤔 What does TT20 stand for?

TT20 is an abbreviation of the ticks*tps/20 formula. It's used to calculate the amount of ticks something takes, while taking the TPS into account.

⚠️ Caveats

TT20 only fixes the symptoms of TPS lag, not the actual lag. It re-calculates the amount of ticks things take. For example, when you're breaking a block it takes the original break time, multiplies it by ticks and divides it by 20 (the maximum TPS). This ensures that the end user feels almost no lag, even if the TPS is very low.
