François reveals essential techniques for optimizing web-based games in 2025, focusing on performance improvements across devices.
He shares his journey transforming a laggy mobile game into a smooth experience using seven methods:
- Adding FPS counters for measurement.
- Implementing object pooling to prevent memory leaks.
- Caching references for faster access.
- Optimizing game loops with selective processing.
- Compressing assets.
- Implementing lazy loading.
- Experimenting with canvas size and rendering methods.
Surprisingly, switching from WebGL to Canvas rendering boosted performance by 30% on older devices—contrary to common assumptions about hardware acceleration.
This guide includes code examples for each optimization technique, to ensure games run smoothly from high-end to budget devices.
