If you experience slow or laggy performance, start here before contacting Support. ## Supported browsers 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](https://www.whatismybrowser.com/guides/how-to-update-your-browser/). ## Laptop or Computer requirements IVION does not require a specific laptop or computer model. For the best viewing experience, use a modern device with an up-to-date version of Google Chrome, Microsoft Edge, Apple Safari, or Mozilla Firefox. Enable hardware acceleration in your browser and keep your browser, operating system, and graphics drivers up to date. Because IVION displays 3D spatial data, performance depends on the device’s graphics capabilities, the size and complexity of the site, and the available system resources. Closing unnecessary applications and browser tabs can improve performance. A fast, stable internet connection with low latency is also important. VPNs, browser extensions, restrictive firewall settings, packet loss, and network congestion can reduce viewing performance. If IVION feels slow, test it in a private browsing window and, if possible, on another network. ## Browser extensions and plugins Browser extensions and plugins can interfere with IVION performance. If you experience unexpected behavior, open your IVION instance in a private (incognito) tab to rule out extension conflicts. ## Network requirements 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 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: 1. Test your upload and download speeds at [fast.com](http://fast.com). 2. 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 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 IVION instance](https://knowledge.navvis.com/docs/troubleshooting-slow-speeds-with-your-navvis-ivion-instance). ## Contact Support **Still experiencing issues?** If performance problems persist after verifying your browser and network setup, contact NavVis Customer Support at [support@navvis.com](mailto:support@navvis.com). --- ### FAQ #### Why does IVION show a black screen in my browser?
