⚡ InputBooster

Stop losing fights because your game dropped a frame.

InputBooster catches your clicks and keypresses even when your FPS tanks — so every swing, sprint, and combo actually lands.

🤔 What does it actually do?

Vanilla Minecraft checks your keyboard and mouse the same number of times per second as your FPS. So at 20 FPS? Only 20 checks per second. That means clicks, sprints, and keypresses can vanish completely during a frame drop.

InputBooster runs a separate polling loop — up to 500 times per second — completely independent of your FPS. Every input gets captured and queued, so nothing is lost even during lag spikes.

Think of it like this: your FPS is how often the game draws — InputBooster is how often it listens.

🎯 What it fixes

Problem	How InputBooster helps
🖱️ Missed clicks	Polls up to 500×/sec and queues clicks for the next tick
🏃 Sprint drops	Re-asserts sprint state every tick, lag can't cancel it
⚡ Sloppy combos	Sub-frame W-tap detection for cleaner hit sequences
↗️ Diagonal slowdown	Auto-Strafe Correction fixes sprint speed loss
💤 AFK kicks during lag	Anti-Idle keeps you in the server during spikes

📊 Smart polling — adjusts automatically

No config needed. The mod reads your current FPS and ramps up when you need it most.

FPS < 30   →   500 Hz  ████████████████████  (max boost)
FPS 30–60  →   250 Hz  ██████████░░░░░░░░░░  (balanced)
FPS 60+    →   100 Hz  ████░░░░░░░░░░░░░░░░  (light)
