And Nvidia has its own game-streaming service, but laggy performance has prevented it from becoming a mainstream choice.Sony bought a game-streaming called OnLive, but shut it down in 2015.But game streaming hasn't had any great successes thus far.This sort of technology could eventually kill off gaming consoles for good, because all you'd need is a TV with game-streaming tech built in, and a controller to play with.It also means that you could potentially be playing an Xbox or PlayStation game on your console, and then leave the house and carry on playing using your iPhone.The resulting effect is 4K PC-style graphics on a smartphone – which is only possible because it's not the phone itself rendering the graphics.Because modern internet connections are so fast, this all happens in milliseconds.You tap and play, and those commands get sent back to Microsoft or Sony, which then inputs them into the game, and sends you the visuals again.Then it would send what's effectively a video of that game to your smartphone.The idea is that a company like Google, Microsoft or Sony would handle the generation of the visuals on powerful computers at its own HQ.Alternatively, you could use game streaming technology.So if you want amazing 4K PC-style graphics, you'll need to fork out for an expensive computer.
That means you need much more computing heft to produce game visuals, compared to a standard movie.But video games render the visuals in real-time, because a game never knows what you'll do next.That's why very unsophisticated computers inside your TV, DVD player, or computer can playback film footage.When you watch a movie, the images you see are already prepared.
