Microsoft is showing off its fledgling xCloud game streaming service at E3, and I was able to sit down and try it out for myself as well as discuss the tech with its General Manager, Kevin LaChapelle. The "cloud based gaming service" warranted only a brief mention in Microsoft's E3 conference , so I was pretty excited to discuss some of the details with Microsoft.

The company had setup a small demo table with a handful of Xbox controllers that had Samsung phones attached to them. Though the way the phones were attached to the controller screamed "pre-beta," the whole setup seemed to work quite well. Picking up the wireless controller I jumped into some Halo 5: Guardians , eager to check out how it felt and if there was any perceptible latency or sluggishness. Microsoft said the games were all being hosted on their Azure data center in the Bay Area, which is approximately 400 miles away.Overall, just like with my demo of Google Stadia , Halo ran pretty much just as I'd expect it to run, since they wouldn't be showing it if it was broken or had issues. Gameplay was smooth, graphics looked pretty darn great, and it was exactly what you would expect to see if you tried streaming Halo from your Xbox to your Android phone.For what it's worth, Microsot said the content being beamed to the demo phones was running at 720p, and to my eyes, it looked pretty good despite being "low res." I asked LaChapelle about plans to also stream content at higher resolutions like 4K, and to more devices like TVs, and he just said it's a "multi-year project," so we can expect more info about those features at a later date.Overall though, xCloud certainly offers a lot of promise. It pretty much works as advertised, and once Microsoft fleshes out all the details it has the potential to add a ton of value for Xbox One owners, especially if it ends up bring a free add-on. None of that is known at this time, however, as Microsoft hasn't even chosen a name for it (xCloud is just the project name, not the actual name). Microsoft promises more details to come, and with rumors of Amazon wanting to enter the game streaming space, this market is about to get really, really interesting.
