Google demonstrated moving gameplay seamlessly from a phone to a tablet and then to a TV, all using Google-powered devices. While existing USB controllers will work on a laptop or PC, Google is also launching a new Stadia Controller that will power the game streaming service. It looks like a cross between an Xbox and PS4 controller, and it will work with the Stadia service by connecting directly through Wi-Fi to link it to a game session in the cloud. This will presumably help with latency and moving a game from one device to another. You can also use a button to capture and share clips straight to YouTube, or use another button to access the Google Assistant.
To power all of this cloud streaming, Google is leveraging its global infrastructure of data centers to ensure servers are as close to players around the world as possible. That’s a key part of Stadia, as lower latency is a necessity to stream games effectively across the internet. Google says it expects to support up to 4K at 60 fps at launch over an internet connection with approximately 25Mbps of bandwidth, and it’s planning to support up to 8K resolutions and 120 fps in the future.
