PVP Optimizer
by tgyki
PVP Optimizer removes the delay that follows a swing, a bow draw, eating or an ender pearl throw, so combat actions register without waiting on the server.
What it does
The mod is a Fabric client mod that targets the wait between a player's input and the result of an action in combat. It covers swinging a sword, axe, pickaxe or any other item, and also crystal, anchor and cart PvP interactions, bows, eating and ender pearls. Changes happen on the client side, so the server does not need the mod to apply them, though a server may run it.
Only the player's client needs the mod, while a server can add it without any setup change. The mod is released under the MIT License and is not open source, and it does not alter server mechanics. Files exist for Fabric only, for 1.21.1 and for the 1.21.8 – 1.21.11 releases, with 1.3 for 1.21.11 as the latest file, published 2026-05-20.
Key features
Swing delay removal
Swinging a sword, axe, pickaxe or other item no longer waits on a server response before the swing shows.
Combat action timing
Crystal, anchor and cart PvP interactions, bows, eating and ender pearls are adjusted to reduce waiting time.
Lightweight design
The changes are limited to combat timing rather than added visuals or additional systems.
Compatible with performance mods
The author states it works alongside common performance mods, so it can be used in a setup that already has them.
