Why 3D sites become slow
Large models, uncompressed assets, too many lights, heavy scripts, and no mobile fallback can make a page feel slow or unstable.
How to keep 3D usable
Use selective scenes, optimized assets, lazy loading, fallbacks, and clear loading states. Not every device needs the same visual load.
- Compress assets
- Lazy-load heavy scenes
- Use mobile fallbacks
- Keep CTA visible
- Test real devices
