Controlling Frame Rate with requestAnimationFrame
requestAnimationFrame provides a consistent and performant way to animate content. However, it's designed to prioritize smoothness over maintaining a specific frame rate. This can sometimes lead to inconsistent frame rates, especially in animations that require precise timing.
Throttle requestAnimationFrame to a Specific Frame Rate
To control the frame rate with requestAnimationFrame, you can throttle its execution using a custom animation loop. This approach allows you to specify a target frame rate and ensure that the drawing code only executes when the specified interval has elapsed.
Here's how to throttle requestAnimationFrame to a specific frame rate:
By throttling requestAnimationFrame to a specific frame rate, you can achieve more consistent animations and reduce any perceived jitteriness. However, it's important to balance this with the potential performance implications, as the custom loop may introduce additional overhead.
