๐Ÿง  X.com Heavy JS Optimizer+

โšก 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 โ€” all without breaking the core site experience.

๐Ÿš€ Features

  • ๐Ÿงน Lightweight CSS Cleanup
    Removes heavy effects (backdrop-filter, blur, gradients) and disables GPU-stressing layers.

  • โš™๏ธ Passive Event Optimization
    Forces passive: true on scroll/touch listeners for smoother rendering.

  • ๐ŸŽž๏ธ Smart Video Control
    โ€ข Only one video can play at a time
    โ€ข Auto-pause when scrolled offscreen
    โ€ข Prevents auto-play and decoding spam

  • ๐Ÿงฉ DOM Feed Garbage Collector
    Keeps only the last N tweets in the DOM to prevent memory bloat.
    (Configurable from userscript menu.)

  • ๐Ÿ“Š Metrics Blocking (Optional)
    Blocks unnecessary telemetry calls like scribe, engagement, and client_event.

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

  • ๐Ÿ’ค Tab Visibility Safety
    Auto-pauses all videos when tab is hidden.

๐Ÿงฐ Menu Commands

Available via ViolentMonkey / TamperMonkey menu:

  • ๐Ÿง  Toggle Aggressive Mode
