TT20Forged (TPS Fixer)
by sj.hub9796
TT20Forged brings the TT20 tick-optimization approach to Forge as an unofficial port, intended for servers whose tick rate falls when player load grows.
What it does
Servers that struggle to keep up with the game can lose ticks, which shows as lag spikes and falling TPS. TT20Forged changes how ticks are processed, adjusting tick handling dynamically so that gameplay stays smoother and more responsive even under heavy load. The idea comes from the original TT20 work by JXSnack, brought to the Forge ecosystem as a separate port.
The mod is server-side only, so players join without installing anything, and only the server needs it. It is published for Forge alone, and the single version it targets is 1.20.1, with the latest file 0.7.1+mc1.20.1 dated 2025-07-15. Because the port is maintained separately from the original, its author is responsible for problems that arise from its use, and bug reports go to the TT20Forged GitHub Issues Page rather than to the original author. The project is not open source; it is distributed under a custom license, and public links exist for the source code and the issue tracker.

How it compares
TT20 (TPS Fixer) is the original mod this port is based on, server-side only, under a custom license, with files for Fabric, Forge, NeoForge and Quilt across 1.12.2 – 26.3. Among the other catalog options, Dynamic Trees Particle Fixer and CreateOptimizer are client-side only, both under All rights reserved and both built for 1.20.1, so they address a different side of the game than server tick processing.
