This article lists the minimum browser and network requirements for a smooth NavVis IVION experience. If you experience slow or laggy performance, start here before contacting Support.
Supported browsers
NavVis IVION requires an up-to-date, modern web browser. The following browsers are supported:
Google Chrome
Microsoft Edge
Apple Safari
Mozilla Firefox
Note: Internet Explorer is not supported.
Keep your browser updated to the latest version to benefit from performance improvements and security patches. For instructions, see How to update your browser.
Browser extensions and plugins
Browser extensions and plugins can interfere with NavVis IVION performance. If you experience unexpected behavior, open your NavVis IVION instance in a private (incognito) tab to rule out extension conflicts.
Network requirements
NavVis IVION requires a fast and stable internet connection. The following factors can affect performance:
Connection speed: A slow internet connection or high latency causes delays when loading data. This is especially noticeable on slower connections or in areas with poor network infrastructure.
Network stability: Packet loss and network congestion reduce data transfer speeds between your device and the NavVis IVION server.
Server distance: The physical distance between your location and the web server affects load times.
Verify your connection
To confirm that your network meets the requirements:
Test your upload and download speeds at fast.com.
If speeds are low, switch to a different network (for example, a mobile hotspot or a private network) and retest.
VPN and firewall considerations
VPN connections and strict firewall settings can degrade NavVis IVION performance. If you suspect either is causing issues, temporarily disable the VPN or switch to a network without strict firewall rules to test.
For detailed troubleshooting steps, see Troubleshooting slow speeds with your NavVis IVION instance.
