🧠 X.com Heavy JS Optimizer+

⚡ Overview

X.com Heavy JS Optimizer+ is a high-performance userscript that dramatically reduces lag, scroll jank, and CPU load on X.com (Twitter).
It intelligently removes redundant animations, limits repainting, pauses offscreen videos, and caps JavaScript frame rates — all without breaking the core site experience.

🚀 Features

  • 🧹 Lightweight CSS Cleanup
    Removes heavy effects (backdrop-filter, blur, gradients) and disables GPU-stressing layers.

  • ⚙️ Passive Event Optimization
    Forces passive: true on scroll/touch listeners for smoother rendering.

  • 🎞️ Smart Video Control
    • Only one video can play at a time
    • Auto-pause when scrolled offscreen
    • Prevents auto-play and decoding spam

  • 🧩 DOM Feed Garbage Collector
    Keeps only the last N tweets in the DOM to prevent memory bloat.
    (Configurable from userscript menu.)

  • 📊 Metrics Blocking (Optional)
    Blocks unnecessary telemetry calls like scribe, engagement, and client_event.

  • ⚡ Aggressive Runtime Mode
    Auto-detects long tasks and dynamically limits FPS (requestAnimationFrame) to maintain stability.

  • 💤 Tab Visibility Safety
    Auto-pauses all videos when tab is hidden.

🧰 Menu Commands

Available via ViolentMonkey / TamperMonkey menu:

  • 🧠 Toggle Aggressive Mode
  • 🧩 Set feed tweet limit
  • 📊 Enable/Disable metrics blocking
