Google suggests that Stadia will achieve "negative latency", possibly through predictive keystrokes



Google has some bold plans for its Stadia streaming service: "Negative Latency".

Madj Bakar, vice president of Google US engineer, told Edge magazine in an interview recently that the company believes streaming games could react faster than a game when run directly on a PC or console , according to PCGamesN . There are two ways to overcome a potential delay between players and Stadia servers: fast-rising FPS to lessen the latency between executing an action and the on-screen display, and a predictive model anticipating player input and this processed advance.

"Ultimately, we think that in a year or two, we'll have games that run faster and are more responsive in the cloud than they are locally, no matter how powerful the local machine is," said Bakar Edge. Google characterizes this as "negative latency".

Obviously, there is no "negative latency" more akin to marketing jargon. As noted by PC Gamer a game developer on Twitter suspected that the push-button feature is not a promise that Stadia will be equipped with targeting or snaps for players kind of ruin the experience – but instead, branding is just talk for the industry forecast. This is a well-known performance trick in programming based on guesswork but in fast-paced games there is a risk of significant desynchronization or rubber banding. Predictive Modeling can be used to generate frames in the cloud in advance and then display them only to the player that matches the action actually taken but with the proviso that it requires much more Bandwidth , (In a very loose sense, Stadia would actually render the game microseconds to the player, not that this is actually new to games .)

In any case, while there is one given the Of great interest in stadiums, the service has also been skeptical that it will actually run almost as well as promised . PC Gamer reported significant latency issues in demos in March 2019, with the reporter writing that he had died five times in the first stage of Doom . (This is not a very difficult level.) Our sister site Kotaku is skeptical that Google may clarify the technical issues that occur in the short term and whether its business model will mean the replacement of game ownership with game access , Then there's the whole question of mods and whether gamers actually want to play single-player titles over the internet; Durable DRM for example has long been vilified and there are tons of people across the country with crappy internet .
