All the graphics and sounds are streamed to a TV or mobile device over the internet. It's interactive - so unlike video streaming, those graphics and sounds are tailored to each player. Home wi-fi routers are just the first step, and we can't see most of it: the street corner communications exchange, miles of fibre-optic cable, core network infrastructure and - ultimately - the data centre. All told, it involves "hundreds of computers, probably thousands", says Mr Hazas. Such estimates are a matter of debate, and some academics told the BBC the assumptions for some figures used are too high.
The Lancaster team also tried to offset the emissions tally by accounting for the carbon savings of fewer plastic consoles being manufactured - another rough estimate.
They also point out that their assumptions are based on game streaming at modern standard p and p resolutions. And while his assumptions in were different from the Lancaster team, Mr Mills did come to similar conclusions. For example, a watt streaming device - like a media stick plugged into a TV - can use an extra watts of power in the network and data centre - making the total greater than local desktop PCs, Mr Mills' team found.
They estimate roughly watts of power is used in the data centre, and about watts are spent on all the internet infrastructure in the middle - for every connected gamer. There are arguments in favour of cloud gaming, however. Gamers could use lower-powered, more energy-efficient devices at home, since all the heavy lifting is done in a data centre. And fewer consoles being manufactured means fewer in landfill at the end of their useful lives. There are also no discs to make, and the cost of transporting them to physical stores vanishes.
Digital game downloads have already been replacing physical copies over time - but they have some of the same problems as streaming. Some popular titles are more than gigabytes in size - a long and power-hungry download process that streaming does not require.
At lower resolutions "it might be in some cases actually be better to stream", he adds. Microsoft says its cloud gaming servers "are more power efficient than a standard home console" and highlights that each server is shared by multiple users "which creates significant energy reduction". Google says its data centres - such as the ones that run its Stadia gaming product - are twice as energy efficient as the average data centre.
And both say all their data centres are carbon neutral. There are currently more than 30 titles available for purchase on the platform, with well over more scheduled for release this year.

Expanded Android and iOS support are planned for later this year. PlayStation Now has been around for a while and offers a relatively wide selection of Playstation 2, 3, and 4 games to stream or download on your Playstation console or Windows PC. The good news is that GeForce Now can be tried for free by anyone, although there are queue times and your sessions are limited to one hour.
The bad news is that many publishers are pulling their games from the platform, so make sure your favorite game is supported before investing too heavily. Game streaming service Vortex takes a different approach to the idea of Netflix for video games. Shadow works a little differently from other cloud gaming services.
Rather than offering an app-based interface, which you would then link with an Epic Store or Steam account, Shadow offers a full virtual Windows PC interface. Microsoft is putting its full weight behind the service, stating that not only will it work for Windows and mobile devices, it will also be a core element of its upcoming Xbox Series X consoles. Check out our beta impressions at the link below. Cloud gaming is well on its way to becoming a huge force in the games industry.
Soon enough many of us might be playing our favorite AAA games on our phones, mediocre laptops, and Chromecasts. What is cloud gaming? Cloud gaming is rapidly becoming more than just a buzzword, but how does it all work? How does cloud gaming work? Game streaming adds input lag, but with the right conditions it's indistinguishable from local gaming.
How much does cloud gaming cost? Ubisoft YouTube. Other costs of cloud gaming. What kind of Cloud Gaming services are there? Here are the ones worth knowing about in Google Stadia.
Playstation Now. Nvidia GeForce Now. Vortex offers apps for Android and Windows, and also supports streaming through Chrome browsers. Shadow Tech. Project xCloud. GeForce Now takes the exact opposite approach of Google Stadia. Free users can play for an hour at a time with the games they already own, and they may need to queue.
Although sessions are limited to an hour, you can start another session immediately. GeForce Now worked with just about every PC game available originally, but publishers were quick to remedy that. Some of the biggest AAA games were removed, but Nvidia has slowly added more back to the platform. The biggest difference between GeForce Now and other cloud gaming platforms is that you actually own your games on another platform. There are two components to this platform: One service for Xbox Game Pass and one for installed games.
The Xbox Game Pass portion provides a specific list of cloud-enabled games locked behind the Ultimate subscription. You can stream these games until Microsoft shuffles them out for other titles or purchase them at a discount and stream them indefinitely more on that in a second.
Right now, the Xbox Game Pass component is limited. Microsoft is currently working on a web app for Safari on Apple devices to skirt around the App Store limitations just like Google Stadia. Previously, Xbox owners could stream their owned and installed games to Windows 10 PCs and Android devices via the Xbox app or the paid OneCast app on Apple devices , but only across the local network.
Now, console owners can stream their games to client devices connected to any network, even cellular, so long as the game is installed on the home console. Your choice in cloud gaming service will largely come down to your preference for particular features or games, but there are a few factors that can help make your choice a little easier.
It works with the PC games you already own, and you can still play those games down the line if you buy a local setup. Shadow is a great second if you want a high-powered PC in the cloud. Stadia works well, too, but you need to pay full price for the games you want to play. Cross-platform gameplay: Out of the three major console companies, Microsoft has shown the greatest commitment to cross-platform play.
The options should only open up further on the new consoles. As seen with Xbox Game Pass and Apple Arcade, you pay for access to a vault of games you download and play locally on your device. As long as you pay for a subscription, you have full access to those games. Further reading I used cloud gaming for a month.
