Does Thread Tweak Mod work on servers?

Yes. This mod works for both single-player worlds and multiplayer servers. Server owners often see better performance when running it on their server jar.

What's the difference between Thread Tweak and Smooth Boot?

Thread Tweak is the actively maintained successor to Smooth Boot. It's updated for newer Minecraft versions and works properly with current Fabric versions.

Will this mod work with other performance mods?

Generally yes, but avoid using multiple CPU optimization mods together. Stick with one and pair it with mods like Lithium or Sodium for best results.

How much FPS improvement should I expect?

It depends on your CPU and what you're running. The bigger the improvement is if you have many mods, run a server, or are generating chunks constantly.

Is there a Forge version?

No, Thread Tweak is Fabric-only. If you need Forge, try similar mods like Smooth Boot for Forge or look at other optimization options.

Thread Tweak Mod Overview

Thread Tweak lets you take control of CPU thread scheduling in Minecraft. If you’re running a server, managing a heavy modpack, or just want your game to run smoother, this mod helps your CPU do the work more efficiently. It’s basically the updated version of the old Smooth Boot mod, but actually maintained and working with modern Minecraft versions.

The mod gives you fine-grained control over how Minecraft uses your processor. Better CPU scheduling means less lag, faster chunk loading, and more stable framerates. It’s one of those under-the-radar performance mods that actually makes a difference.
