  1. Once the game is launched in its own window, the game will connect to the Pixel Streaming server process running on the VM. In order to connect a browser from your local machine to the game, you must know the public IP address or the DNS Name of the Game Development VM. An easy place to find this information is on the Overview panel of the VM instance in the Azure Portal.
