Three.js WebGL Performance Optimization

Marketing sites using Three.js must balance visual impact with LCP—lazy-init WebGL, cap draw calls, and provide static fallbacks.

Direct answer: Marketing sites using Three.js must balance visual impact with LCP—lazy-init WebGL, cap draw calls, and provide static fallbacks.

Initialization Strategy

Show CSS/static hero immediately. Load Three.js after first paint via requestIdleCallback. Cap particle count for mobile (50% of desktop).

Target 60fps on M1 Mac / mid Android. Limit lights, shadows, and post-processing. Use instanced meshes for particles.

Draco-compressed GLB. Texture atlases. Max 1024px textures for decorative 3D. CDN delivery.

Detect WebGL unsupported / low GPU. Show video loop or high-res static image. Never blank hero.

Key Insight: Build hub-and-spoke content around WebGL Development—single pages rarely win in AI synthesis or traditional SERPs.
