    Until round trips between the server and client are guaranteed to be under 50ms, the lag will feel unbearable. If someone is playing a racing game and has to deal with a second between the time they begin turning and the time they actually see it turn this service will be dead before it begins.

      I also strongly doubt that any kind of game on this platform can be enjoyed by people who are sensitive to input latency. For example my old high quality PVA TFT panel used an overdrive circuit to reduce ghosting. The overdrive logic in TFT panels usually buffers about 1 or 2 full frames to analyze and optimize the pixel voltages which leads to about 20-50ms input latency. I for one already notice it when I just work to the point where it annoys me when the desktop or terminal sessions somehow always feel sluggish, let alone fast 3D games.

      I can't imagine that the complete round-trip time for sending my input over the internet, waiting for a frame to be rendered and encoded remotely, sent back over the internet, decoded and displayed locally would be less than 20ms and then you'd still have the latency of your display. It might be bearable with a very fast internet connection and a CRT display which has 0ms input latency.

      Maybe others aren't that sensitive to latency and can enjoy at least slower games like turn-based strategy with this service. Good for them.

              Assume 60 fps, synced with 60Hz monitor. That's 16.7ms per frame, and usually means a target budget of 16.7ms per iteration in the game loop - and input is probably processed exactly once in the game loop. Consider also that many decent displays already lag by a frame or two. So in a local hardware situation, you already have a built-in lag somewhere in the region of 30ms or so, pretending there isn't any lag in the actual hardware path between devices and what the OS surfaces to apps.

              Now, given the above assumptions, but factoring in your posited reactive input model (i.e. no delay from game loop), you think that's good enough? The way I see it, it can only be good enough if the round trip averages to less than 16ms or so; and even then, it's not great. I've long noticed the lag in games since moving from CRT to LCD, and I can even see the lag between moving my mouse and the pointer moving across the screen - it's small but perceptible, and is either caused by the mouse / usb / driver path or by the LCD delay.

              But I can't realistically see a 16ms or so round-trip being achievable outside heavily populated areas and without lots of expensive hardware very close to local loops. As it is, Google.com is 29ms away from my machine, and it's still slow to download the front page's HTML content - (yes, I know, TCP connection, several round trips, etc.) - on the order of 200ms or so.

              It seems to me that round trips on the order of 50 to 100+ms are more likely, and delays of that nature are highly, highly noticeable in twitch FPSes - especially when it comes to things like changing the view direction. Pretty much all multiplayer FPSes don't wait for a server round-trip for changing the view direction. In that situation twitch FPSes will suck.

              Other kinds of games may work better.

                You hit the nail on the head right there, the view direction.

                Most games do all sorts of predictive wizardry to make the shooting work over internet latencies, but every game allows the view direction to occur completely locally, because even a slight lag makes the player feel like a drunkard. Many games also allow the local client to compute some of the 'game mechanics' locally, and then 'verify' the results with the server later.

      One I wonder about is what kind of servers they are supposedly using. The problem is that modern games demand a modern GPU to look good. The kind of processing needed cannot be done on any sort of reasonable processor in realtime. Also, GPUs aren't really set up to work in parallel these days. What I mean is if you try to have a system with multiple GPUs and running multiple 3D games on them, you are going to

        just one little point:

        Hell, MS would be interested in doing it non-virtualized. Be a cool selling point of a new Windows if you didn't need a GPU anymore.

        DirectX has a software mode implementation (the Reference Rasterizer) that is included with the SDK. It is just as fast as one might expect (read: horribly horribly slow) but does the entire shebang in software. If you threw enough computing power at it, you could conceptually match GPU performance. However, this begs the question as to how much computing power they can afford to throw at it while keeping costs down enough to, at least, break even (a curse word to investors).

      • The one thing that isn't addressed here is if there is any software engineering going on to the games... my guess is that they need to do some rewriting to key parts of the software.

        The whole point of a GPU is to handle specific, graphic related tasks, and that frees up the main processor to handle everything else. So why not have one set of servers that are tasked with processing data meant for a single GPU, another set that processes physics, and one that does sound, all that feed into another set that

      I still maintain that this simply can't work, and that it's an absolutely braindead money pit of an idea if it's not a total scam.

      Well it could work, but only for sedentary games where a bit of lag doesn't kill the experience, it might even offer some interesting scenarios for network play such as pitting one street or town against another.

      Even so, the tech just seems to be a bit of a white elephant. Latency does limit what it can do, as will the sort of loads the server at the other end can tolerate. I

      You obviously didn't watch the video at all. While you're being an asshole about the idea, the guy presenting during the presentation covered all of your strawmen.

      1) "fill instance of the most powerful PC you can throw at it" - Uh, no. When you move from workstation class hardware to server hardware, the "ceilings" change. But, for games like Crysis, they do, indeed, use a big GPU per instance.

      2) "720p video in realtime that no codec today can deliver" - Too bad you didn't watch the video. Turns out, this is the same team that brought us QuickTime before video codecs were even discussed. He also describes exactly how they pulled it off, started with scrapping the stream-based design paradigm, using a feedback loop based design paradigm, and creating a new encoder that looks great in motion encoded and decoded in real time (as one of the weaknesses, you can't pause it or it looks like shit).

      3) "Presumably happen on the same computing hardware..." - Actually, no. As the presenter describes, the codec taxed even the dual quad core xeons that it was developed on. Then they fabbed custom chips that do nothing but implement the encoding algorithm. It's entirely hardware accelerated encoding, two chips per user on custom boards.

      I also thought the entire process sounded like a big stupid scam, but before I declared the mighty victory of common sense, talking out of my ass, I went ahead and watched the video.

      Do you know who Steve Pearlman is? He pretty much gave us QuickTime. He's got a history of incredibly forward thinking ideas, some took off, some didn't. This isn't like the Phantom console, where some MBA morons tried to do something. I don't think Pearlman would be out there showing this off unless there was some real meat going on here.

  • Great concept, I can't wait to play with it in person :) A few thoughts:

    I'm a little skeptical about how robustly it will perform, but I am sure they will have a chance to prove their technology soon. I'm sure everyone who's played online has dealt with lag spikes, just due to random congestion, noise, route changes, that sort of thing. It seems that this system will be much more sensitive to those kinds of network delays.

    I think the most interesting part was the (lack of) answer about how the compression works.

    They claim 80ms round-trip latency from button push to image display. Running a game on a server and screen-scraping in ~20ms is fairly easy. With proper datacenter placement and peering agreements ~50ms round-trip ping times are reasonable (if somewhat optimistic). The issue is how do you compress the 720p image and send it back in 10ms with reasonable bandwidth.

    They're claiming 1ms compression, 8ms decompression (125hz), and 5mbit 720p streams. The compression is using a custom ASIC, so that's completely believable. Decompressing at 120hz on any generic hardware (they specifically said no GPU help) means it has to be an extremely simple protocol. The biggest question is how do you reach "HD-quality" at only 5mbit when you are not doing group-of-pictures compression (keyframes and diffs from the keyframe). Mind you that a standard DVD is 10mbit, so they're claiming higher resolution with half the bitrate and no keyframing. Obviously H264 gets better quality/bit than DVDs, but it does so by using even more complex keyframing and diffs and is far too CPU intensive for their target platforms (it's hard to watch 30fps H264 trailers on many machines, let alone a 60fps stream). The only hint he gave was some mumbling about visual perception, and the statement that their compression only looks good in motion (if you paused the stream it would look terrible).

    Any ideas as to how the compression works?

    • Exactly, their compression algorithim will have to be an absolute quantum leap in both quality and cpu efficiency i.e. magnitudes faster than anything else on the market.

      And that's just the compression algorithm.

        ISTR a broadcast pro posting that 1ms HD compression was becoming more common on live broadcast hardware. I find it believable, especially (as the GP pointed out) if they're making custom chips for the purpose.

        They're entirely open about the fact that colo is their strategy. If you're not near one of their colo server farms, you won't be accepted as a customer.

    • Near the end of the video during the Q&A, they answered a bit about it. They actually created their own compression, then had encoding custom chips made for it.

      Basically, video encoding hardware geared exactly to their new compression.

    • Ya. A universal truth with new perceptually compressed formats seems to be that the more quality you want in a given size, the most you pay for it in terms of power needed to compress and decompress the data. You get trickier with the math and it gets you more for less, but at the cost of calculations.

      In fact, you find that some seemingly "inferior" compressions were invented for just that reason. DV is a good example. It came around in 1995 for use in digital video cameras. However, when you look at it by

    • What they're selling is the ability to play the latest games on maximum settings without ever having to upgrade your computer (or even have one - did you miss the very cheap hardware version they have for TVs?). You can even e.g. play Crysis from your netbook (or iPhone, as shown). It sounds like it might be worth it, depending on the price.

      That said, I'm still very sceptical about the technical feasibility of the whole thing.

  • All these whiners claim latency will kill this before it ever starts. Guess what? FPS is not the only game category. I game all the time, but latency means nothing to games like Civ4, Neverwinter, and thousands of others. Sure, lower latency is a great goal to aim for, but this platform is a good step towards moving MMOGs onto lower powered clients. The games are just an excuse to extend their reach to more customers in a "new" way, so they can sell them things.

For me, I can usually get an average ping of about ~80ms to any given person or site on the internet; Even if the video feed had no additional overhead (and it invariably does), that still takes at least 80ms from when I send input and get to see a response on-screen, at the best of times. People already have issues with some LCD displays and input lag, and that's only on the measure of up to 10-40ms. Add in
