GameStream and GRID

The final software features that Shield Tablet brings to the table are GameStream and GRID. These are effectively methods of turning the tablet into a thin client, as all of the rendering/computation is done on a computer either in the LAN or on a server in San Jose. From a technical perspective, both work great as long as the connection has high bandwidth and low latency.  For GRID, I managed to get a great user experience on a symmetrical 10 Mbps connection and around 10ms latency to the server. Games like Saints Row 3 played as if running on a console when the device is actually streaming from NVIDIA servers. From the user’s perspective, it’s a matter of going into the app drawer, opening GRID, and selecting a game. It’s simple and given sufficient server coverage I could easily see a Netflix-style usage model taking off quite successfully.

Although I didn’t spend as much time with GameStream, I didn’t detect any input lag and for the most part it’s just as simple. As long as a GameStream-enabled PC is on the same network, accessing GameStream compatible games is just a matter of going to the Shield Hub application, entering a four digit code on the PC to pair it with the tablet, and selecting a game. GameStream also works remotely, but the same caveats that come with GRID apply to GameStream on both the server and client end. Of course, the games that will run on GameStream have to be carefully selected. While it’s fully possible to play a twitch shooter like Call of Duty through GameStream, trying to use a controller in multiplayer is simply a massive disadvantage against people that are competent with a mouse and keyboard. I've included a screenshot of Mirror's Edge that I took while testing GameStream.

Gaming Ecosystem

Ultimately, I’m a bit conflicted on whether GameStream and GRID are really designed to stand on their own though. GameStream only works while you’re at home, and GRID is highly dependent upon low latency and also needs around 10 Mbps download and 5 Mbps upload for an ideal experience. Due to the latency requirement and the fact that the only GRID server bank is in San Jose, the very low latencies that GRID is best suited for are generally only achievable in California and parts of other nearby states. They’re definitely great in the situations that they work, but ultimately the native game library has to stand alone. To this end, the tablet is in a far better situation than the original Shield. The number of games that provide a quality gaming experience is now leaps and bounds better than what we saw with the launch of the Shield Portable. Trine 2 is included out of the box, and while I didn’t get a chance to try co-op mode it’s a compelling experience that once needed GameStream or GRID to be played on Shield. Along the same lines, the Grand Theft Auto series, Half Life 2, and Portal all play surprisingly well.

Fundamentally though, I don’t think single player games alone will sell Shield as a gaming platform. A single player game can only have a certain amount of replay value. Something like Half Life 2 might have 12 hours of gameplay at best. In comparison, multiplayer has massive amounts of replay value because even the same map can play out differently depending upon the people that play in the round. It’s that factor that makes it possible for people to spend 1200 hours playing a game like Battlefield 2. Unfortunately, for the most part the Shield tablet has a game library that seems to be skewed towards single player games. Fortunately, NVIDIA seems to understand this. While I haven’t been able to play War Thunder on Shield tablet, the promise of compelling multiplayer games on this device would be a strong enough reason to excuse potential shortcomings in other areas. Although it's good that an immersive multiplayer title is coming to Shield tablet, the key point of emphasis is that people playing a Shield device can play with those on console or PC as well. Until NVIDIA hits critical mass for Shield device adoption, multiplayer titles that only allow people on Shield to play with others on Shield will struggle because people won't play multiplayer unless there are other people to play with.

    Thought Nvidia had a real killer here.

    Until I saw how crappy the screen is. On a tablet having such crappy color reproduction is just not going to cut it.

    Overall the Shield tablet display is not bad but not great. The black levels, contrast ratio, and saturation accuracy are quite a bit better on Shield tablet compared to iPad Mini Retina. The max brightness and white point accuracy are slightly better on Shield tablet compared to iPad Mini Retina. The grayscale and GMB accuracy are quite a bit worse, however, and are the two areas that need some work. Reply

    I agree that it's not bad, but the truth is that most games will be just as good on some of the top tablets (http://www.consumertop.com/best-tablets/ ), and they will also be better for all other tasks. Therefore I don't see the point of the Nvidia Shield. Reply

    You must have skipped the cpu and gpu benchmarks... Reply

    Color accuracy is pretty much irrelevant for gaming. Reply

    Well yeah, if you're a moron. Reply

    that's mean... also you are wrong color accuracy is so irreverent in gaming... Reply

    Games already use low resolution color palettes. Textures almost never have more than 8 bits per channel (and are often compressed beyond that), and lighting calculations and sampling error is already going to produce generally "wrong" colors with respect to the real world. You're absolutely fooling yourself if you believe you will see a noticeable difference between this and a more accurate display while gaming. Reply

    "Games" use an incredibly varied set of graphical abilities. Maybe first-person shooters are different, and a lot of hyper-realistic AAA games in general; but there are plenty of games that are bright or cel-shaded, and those look a lot better on a screen with rich colours.

    You can't just say a display is good or bad. The reason they give us all these specs is so that we can make our own choices. Someone who plays games with muted or washed-out colours can decided that it's fine, and that this works for them based on the tradeoffs it makes.

    I agree there are cases, typically indie games, where this is true, but this is an incredibly small subset of the game market, and also generally not the target audience of such a device. The shield seems to be targeted more at heavy gamers, especially those who wish to stream games from a high end PC in another room. These are the people who typically have many AAA titles and games where the graphics are so complex, and the amount of estimation used to compute lighting and texture quality is off from realistic values enough to not even realize that in cases of perfect color reproduction by the display, the game could very easily have a high error from the "real world" value anyway.
