Thread Tweak 9minecraft Mod gives you control over how the game uses your computer’s brain, the CPU. Minecraft usually decides on its own how to handle background jobs like loading chunks or saving the world. This mod lets you change those rules so the game shares power better with other programs running on your computer. You can set up the background worker threads to stop lag spikes when the game tries to do too much at once. It works on both regular single-player and dedicated servers without changing anything about how you play the game.

Thread Tweak 9minecraft Mod was listed here as Smooth Boot for a short time. ThreadTweak is the continued fork of Smooth Boot by UltimateBoomer, so both names refer to the same mod and the same settings file, threadtweak.json.

  • Works quietly in the background on both your local game client and big multiplayer servers.
  • Keeps the vanilla gameplay exactly the same while changing the technical math behind the scenes.
