What's New v1.1.0a January 2026

Major update to Ethereal WM!

We significantly improved our networking and protocols to increase streaming performance and stability. Now there are no artifacts when streaming*, audio is better synced, and less latency!

*Streaming performance varies based on your internet, router, and connection. If significant artifacts or latency occurs, try lowering the bitrate in the stream settings on the host.

⚠️ Important: These are significant changes to the host and client. They are not backwards compatible. It is recommended to uninstall the host and client, and reinstall the versions in this zip file. The uninstaller can be found in the installed file location.

Installation

  1. Download and extract the zip file
  2. Install EtherealHost-1.1.0-Setup on your Windows PC
  3. Install EtherealClient-debug.apk on your Quest (via SideQuest or ADB)
  4. Make sure both devices are on the same WiFi network
  5. Launch Ethereal on your Quest and connect to your PC
