Particle Rain — Ultra Performance

A high-performance particle rain simulation in HTML5 Canvas.
Push your device to the limit with up to 2,000,000 particles and ultra stress-testing features.
Includes auto-throttle and smart sampling so the UI stays responsive even at very low FPS.

Features

• Max particles: up to 2,000,000 (configurable)
• Burst spawn: up to 50,000 per click
• Gravity, wind, size controls
• Auto-throttle: adapts rendering for low FPS to avoid device crash
• Stress mode: spawn as many as your device can handle
• Responsive UI: control panel with real-time stats

Usage

1. Open index.html in your browser.
2. Use the UI to configure particle count, burst size, gravity, wind, and particle size.
3. Start, stop, stress, or clear particles from the control panel.
4. Tap/click on the canvas to spawn bursts. Long press for continuous bursts.
5. Watch FPS and particle stats — auto-throttle keeps the app running even under extreme load.

Warning

• High particle counts can freeze or crash devices.
• Use stress mode and high values at your own risk!
• Auto-throttle will try to recover, but extremely high settings may require a page reload.
