No Lag TickRateChanger
by wartori54
No Lag TickRateChanger lets a Fabric server or client change how many ticks run per second, with the input lag kept low.
What it does
The mod changes the tick rate, meaning the number of game ticks per second, which is 20 by default in Minecraft. Slowing the tick rate does not increase input lag here, because the mod checks player inputs such as clicks in a separate loop that does not depend on the tick rate. Files are published for 1.17 and 1.17.1 on Fabric only, with 0.3 for 1.17.1 as the latest file under the Apache License 2.0, and the mod is open source. Every player and the server need a copy of the mod.
Key features
Adjustable tick rate
The tick rate can be slowed down or sped up, changing how fast game time passes.
Input checked separately
Player inputs are read in their own loop, so clicks and keys respond without waiting on the tick rate.
Low input lag at slow speeds
At 0.5 ticks per second the input lag stays near that of the default 20, instead of growing to about 2 seconds.
Compatibility

What the author says
This is another Tick Rate Changer mod, that lets you slow down and speed up time to perform epic gameplay blah blah blah… In a common Tick Rate Changer, you change the tick per second that Minecraft runs at (by default 20), and because Minecraft check for inputs (like clicking) every tick, the input lag increases…
