## Browser Recommendations

For the best experience, use the latest version of **Google Chrome** or **Microsoft Edge**. These browsers provide the most consistent WebGL performance and are regularly tested with NavNX.

Safari and Firefox are supported but may exhibit minor rendering differences in the 3D viewer.
