Google tries to reassure players about Stadia pace and latency issues

SAN FRANCISCO—Google’s Phil Harrison tells Ars that Stadia sport streaming ought to present a clean, full-resolution expertise on Web connections above a threshold of 20 to 30mbps, a degree that ought to enable for “hundreds of millions of potential players in the markets that we’re talking about.”

Whereas the corporate set a threshold of 25mbps for its beta testing late last year, Harrison instructed Ars that “in actual fact, we only use an average of 20mbps; it obviously bounces up and down depending on the scene.” Since that beta, Harrison mentioned infrastructure and codec enhancements “now allow us to get up to 4K resolution [at 60 frames per second] within about 30mbps. So we saw a dramatic increase in quality between then and now without a significant increase in bandwidth.”

Even at that threshold, Harrison acknowledges that “I know [Stadia] won’t reach everybody [and] I respect that some people will be frustrated by that. But I suspect that some of those people don’t get a great YouTube experience, they might get a good Netflix experience today. The good news is the Internet continues to grow in quality and reach. So there is a bit of a rising tide that lifts all boats, with 5G potentially helping that equation in the future. That’s a little bit over the horizon today, but it’s I think going to come into view pretty quickly.”

The latency difficulty

With streaming gaming, the bandwidth to offer a clean, high-resolution video is simply a part of the equation. Added latency between participant inputs and reactions on the display generally is a killer downside for all kinds of video games.

In our interview, Harrison would not go into particulars on Google’s latency mitigation efforts or discuss a threshold for added latency that the corporate would contemplate acceptable. “Different games have different sensitivities,” Harrison provided.

However there have been just a few factors in our chat the place he did allude to some proprietary secret sauce that will reduce the round-trip time for participant enter.

That features “innovations that we have put in our data centers at the hardware level which are not visible to the outside world,” and “a lot of work in the encode end of the equation in the data center, a lot of which is not disclosed publicly.” Harrison additionally cited “the partnerships we have with the ISPs, the fact that all the data sits on Google’s backbone for as much of the experience as possible” as actually enhancing the expertise.

Outdoors the information heart, Harrison mentioned Google can be offering “insights to players on how to tune their experience and get the right hardware in their homes.” Which may imply shopping for “a different type of router” or steering individuals towards Google’s own Wi-Fi mesh network hardware (which, to be clear, won’t be the one supported router).

Utilizing a Stadia controller linked through Wi-Fi additionally helps with the latency difficulty, Harrison mentioned. “Bluetooth is slow, Bluetooth would add additional hops that are not necessary; it would add unnecessary latency to the equation. [A Wi-Fi controller] also allows us to integrate things like the Google Assistant technology at a really native level. It’s the best architecture, it gives us the best flexibility, and it also allows you as a player this seamless movement between screens.”

Harrison expressed confidence that the degrees of lag concerned in a regular Stadia expertise have been appropriate with even the twitchiest, most reflex-heavy sorts of video games. He additionally let slip that “we have a couple of leading fighting games in development on our platform.”

Even with all the corporate’s efforts to cut back latency, although, Harrison allowed that there’s a sure degree of participant that will not settle for any further lag. “I fully respect that there is a top of that [esports player] pyramid, who are typically players wearing logo t-shirts in a comfy gamer chair, and they’re investing in lowest possible latency mouse pads. Maybe we’re not going to reach those players day one. But I think that aspirational pyramid beneath the pinnacle pro players is absolutely for Stadia.”

Who is that this for?

Since lengthy earlier than Stadia’s announcement, some critics have thought-about streaming gaming as an answer in quest of an issue—a service that players at massive aren’t actually asking for. However Harrison says Google’s market analysis has recognized two broad classes of participant that “we believe will be excited by Stadia.”

The primary is “leading-edge players that understand the technology of 4K, 60 frames per second. They know what HDMI means to quality. They will love the ability to take a game they love across any screen time.”

The second, Harrison mentioned, is a extra budget-conscious gamer “that frankly cannot afford to keep up with the rate of change in the hardware generations, whether it’s on a PC or console. My observation is console cycles are starting to speed up again, not slow down, and that’s an expensive capital expenditure to keep up with… There is a player that loves to play, wants to play, but can’t play on the latest, greatest machines.”

Harrison would not go into particulars on the kind of bills a Stadia buyer could be going through as an alternative of {hardware} prices and even the potential varieties of monetization buildings the service would use. He did promise extra data on that rating in the summertime, although.

Harrison mentioned he revered earlier sport streaming efforts that “were all pioneers and should be applauded for taking those bold steps.” That mentioned, he urged that “it takes a fairly unique set of capabilities to really get this to scale. Google is one of the very, very small group of companies that has the technology, the reach, and the long view to pull this off.”

“If you were to approach this as a startup, you would be reliant on somebody else’s infrastructure,” he mentioned. “And you’re automatically introducing a latency and performance hit, even before you get to the economic hit.”
