About this Mod

Projectile Optimizer!

This mod improves projectile responsiveness by instantly showing thrown projectiles client-side before the server confirms them.

Information

By default, Minecraft waits for the server to spawn thrown projectiles such as ender pearls and wind charges. While this delay is barely noticeable on low ping, it becomes much more noticeable on high ping and can make projectiles feel delayed or unresponsive after being thrown. This optimizer instantly creates a temporary client-side projectile the moment the item is used, allowing the throw to appear visually on the exact tick it happens.

Once the server sends the real projectile, the temporary client-side projectile is removed and replaced by the server-confirmed one. The server still fully controls the actual projectile behavior, collision, teleportation, and damage, while the client handles the immediate visual feedback to reduce perceived latency.

Frequently Asked Questions

Does Projectile Optimizer need to be installed on the Minecraft server?

No. Modrinth marks Projectile Optimizer as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does Projectile Optimizer require?

Use a file for fabric and your exact Minecraft version. Supported versions include 1.21.11, 1.21.10, 1.21.9. Files for different loaders are not interchangeable.

Projectile Optimizer is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
