KryptonReno's Fabric Patcher

by 4x

KryptonReno's Fabric Patcher is an extension for Krypton that adds further network optimizations on Fabric, Quilt and as a Java agent.

FabricQuiltJava AgentClient or server, optionalGNU Lesser General Public License v3.0 onlyOpen source1.21.4 – 26.1.2

What it does

The patcher is ported from KryptonReno and extends Krypton Fabric with more network-level optimizations. Mixin enablement is controlled through parameters passed in the Java startup arguments, so a server owner can switch individual patches without changing mod files. Krypton is an optional dependency, and the patcher is not meant to run alongside Cardboard, which it is listed as incompatible with.

Installation works on the Fabric, Quilt and Java Agent loaders. Either side can run it, and neither needs it. Files cover 1.21.4 – 26.1.2 with snapshot builds published, under the GNU Lesser General Public License v3.0 only, so the project is open source.

Key features

  1. Additional network optimizations

    Adds optimizations to network handling on top of the base Krypton Fabric changes.

  2. Startup-parameter mixin control

    Individual mixins can be enabled or disabled through Java startup parameters.

  3. Windows acceleration via RecastLib

    RecastLib provides acceleration features on Windows x64 and arm64 systems.

Questions

Does KryptonReno's Fabric Patcher require Krypton?

Krypton is listed as an optional dependency, so the patcher runs without it, though it was built to extend Krypton Fabric.

Can KryptonReno's Fabric Patcher run alongside Cardboard?

No. The mod is listed as incompatible with Cardboard, so the two should not be installed together.
