Crossbow Optimizer
by Walksy
Crossbow Optimizer moves crossbow reloading and firing updates to the client, so server ping no longer slows down a reload.
What it does
Normally a crossbow reload waits on a round trip: the client sends a use-item packet, the server processes it, then sends the charged state back. Shooting has the same delay, because the next reload cannot begin until the server confirms the shot and returns the empty state. On a high-ping connection this stacks into noticeable waits, and the server can cancel reloads at random when updates arrive out of sync.
The mod runs the reload on the client, so it does not wait for those packets. It empties the crossbow as soon as a shot is fired and lets the next reload begin immediately. It also keeps the server from cancelling an active reload. Installation requires WalksyLib, and the mod is published for Fabric, for 17 release versions, under the MIT License and open source.
Key features
Reload computed locally
Reload progress is tracked on the player's machine, so the wait for server confirmation no longer sets the pace.
Immediate reload after firing
The crossbow empties as soon as a shot is fired, and the next reload starts without waiting for ping.
Blocked server cancels
Active reloads are kept from being cancelled when high latency causes the server to fall out of sync.

Use cases
Playing on remote servers
Players whose connection has high latency get the same reload timing as players with a short ping.
Crossbow-heavy combat
Fights that rely on repeated shots benefit from reloads that start as soon as the previous shot leaves the crossbow.
Who it’s for: Players who use crossbows on multiplayer servers with higher latency, and players who want reload timing that does not depend on the connection.

What the author says
This mod handles crossbow reloading completely on the client, reducing the effect of ping and ensuring the server doesn't interrupt the reloading process. When reloading, the client must wait for the use-item packet to reach the server, wait for the server to process the reload, and finally wait for the server to…
