requestAnimationFrame

Driving each clock separately with setInterval would cause 500 independent timers to queue up individually, and when callbacks pile up the event loop burden is considerable; a more reasonable approach is to drive all clocks with a single unified requestAnimationFrame loop and batch-update them based on elapsed time.

Using a single rAF loop to iterate over all clocks and compute angles or seconds from the time difference between performance.now() and the previous frame reduces scheduling overhead from O(500) to O(1).

setInterval has the timer thread push callbacks into the task queue at fixed intervals, the intervals are imprecise, and each timer queues independently; requestAnimationFrame aligns callbacks with the browser's display refresh rhythm (typically 60 Hz, about once every 16.7 ms), executes only once per frame, and automatically pauses when the tab is not visible to reduce background power consumption.

Lumen OS adopts a ring buffer plus RAF loop pattern: incoming WebSocket packets are pushed into an in-memory queue with no React overhead; a decoupled requestAnimationFrame loop polls the buffer and draws updates directly to the DOM or Canvas, ensuring the browser renders only at the monitor's refresh rate.

requestAnimationFrame is a frame-scheduling API provided by the browser that aligns callbacks to run just before the next repaint, firing about every 16.7 milliseconds on a 60Hz screen and automatically pausing when the tab is hidden.

Frame-by-frame screenshotting requires 'freezing' the page's CSS animations or requestAnimationFrame loop at a specified moment; otherwise the screenshot timing and animation state will be out of sync.

Throttling via requestAnimationFrame can merge updates from multiple tokens into a single frame for a unified DOM write, reducing the number of browser layout and repaint operations.

requestAnimationFrame allows developers to align DOM updates with the browser's screen refresh cycle (typically 60fps, approximately 16ms per frame).

Mainstream monitors refresh at 60Hz, i.e., 60 frames per second with approximately 16.67ms per frame, and the browser's requestAnimationFrame API callbacks follow this rhythm.

Particle Studio uses requestAnimationFrame (RAF) to achieve smooth animation rendering, as RAF automatically synchronizes with the monitor's refresh rate (typically 60Hz).
