Google has announced its game streaming platform Stadia. The platform allows gamers to play 3D games via their browser.

According to a recent announcement, the platform will be "for everyone", but game streaming still requires a powerful internet connection to make it run smoothly.

The platform was tested in 2018 with Project Stream when Google tested a Ubisoft title streamed at 1080P at 60 frames per second.

Google will make available to game developers its data centers to deliver high fidelity graphics to more gamers. This is because streaming doesn't require powerful hardware to render graphics because the frames are rendered by Google's machines instead.

At launch the platform will support 4K resolution streaming at 60 frames per second. 8K resolution streaming will be supported at a later date. A second 4K resolution stream will be available for players to share to YouTube.

The platform is said to make use of multi-gpu machines delivering up to 10.7 GPU teraflops. This is higher than Sony's PlayStation 4 and Microsoft's Xbox One at 4.2 teraflops and 6.0 teraflops respectively. Nvidia's Titan V GPU delivers 12.3 teraflops, which is higher than Stadia's capabilities.

A game controller was also announced that is similar to the one displayed in Google's recent patent filing. The controller has a seperate button to instantly share gameplay to YouTube because all gameplay is already being recorded while playing via its stream.
