3D world is fully functional with Windows 10 or macOS (Catalina 10.15.7 or above).
In addition, you need internet connection with the network bandwidth required for the video conference or stream. If your computer manages Zoom/Teams/Skype/other tools, you are good to go.
However the app is quite power thirsty, so please do not forget to plug in your charger.
We highly recommend to use mouse to operate in the 3D world. You can handle it by using touchpad or other pointing device, mouse is just the most convenient.
