Lost Input Fix
A lightweight client-side mod that fixes lost or dropped mouse and keyboard input at low FPS in Minecraft.
The Problem
When Minecraft's FPS drops low, the game can miss input events — mouse clicks, key presses and movements get "lost" because the input thread can't keep up with the game loop. This causes:
- Clicks that don't register (breaking blocks, attacking, GUI interaction)
- Keypresses that are ignored (movement, jumping, hotbar)
- Choppy, unresponsive controls exactly when your PC struggles the most
The Fix
Lost Input Fix intercepts and buffers input events so that nothing gets lost, even at very low frame rates. Your inputs are queued and reliably applied to the game.
Features
- Fixes dropped mouse clicks at low FPS
- Fixes dropped keyboard input at low FPS
- Lightweight — near-zero performance impact
- Works on Fabric
Installation
- Install Fabric Loader
- Drop the mod .jar into your
modsfolder - Done! No configuration needed
Notes
Client-side only — no need to install on servers. Works best combined with performance mods such as Sodium or OptiFine.
