Install in the game only; not needed on the server
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.
