Which Hardware Considerations Matter During Development?

Tom's Hardware Interviews Four Android And iOS Game Developers
By

Tom's Hardware: Even game developers trying simplify their business by focusing on a single operating system still struggle with supporting updates and different hardware specifications. For example, Android comes in several versions and supports an array of platforms including OMAP, Snapdragon, Tegra, and Exynos, with Intel and Huawei soon to follow. How do you cope with different hardware and software variables?

Fishlabs: The Android platform is characterized by a very high level of fragmentation. For us, this is particularly relevant because we have to make sure that the texture compression of our titles is always optimized for and adjusted to the capabilities of the devices in question. For the upcoming All Android version of Galaxy on Fire 2, for example, we had to create half a dozen individual texture sets in order to make sure that the game runs as smoothly as possible on each of the 700+ supported devices. If all goes as planned, the app will recognize the corresponding device’s GPU automatically and download the required texture assets during the installation process.

The CPU, on the other hand, does not yet play as important of a role for us because all our games are GPU-bound. That is to say the GPU limits our titles’ performances. So far, all Fishlabs games perform smoothly on single-core devices as well.

Madfinger: Thanks to our Unity 3D engine, different architectures and OS version do not need much consideration. We can pay more attention to the game itself, instead of the hardware. We focus on Tegra devices because Nvidia provides us with a great support. Moreover, all Tegra devices have similar specifications, so we use it as our main development platform right now.

Mediocre: We originally ported Sprinkle for the Tegra platform. After a couple of months, during which we had a chance to get a feel for the Android market, we decided to do a general port. We restricted ourselves to Android 2.3 and ARM v7 to simplify the development, and block-out devices that are not powerful enough to run the complex fluid simulation in Sprinkle.

We set up a beta program where anyone could apply, and we selected about 50 people with different devices to try the game and report issues. The whole process was smooth, and within a few weeks, Sprinkle was stable on most devices. Hardware manufacturers typically make it sound like their product is very different from the competition, while in reality they are all actually similar from a developer point of view.

Vector Unit: Our approach is to get a representative sampling of each platform in-house for testing, cover as many cases as we can, and then respond to specific issues raised by users when new devices come out.

Personally, I think any hardware like Tegra that supports DirectX textures is easiest to work with. PowerVR has many restrictions (like square textures for compression, as an example). But ultimately, they are all fairly similar.

Tom's Hardware: Current mobile benchmarks used to identify the best-performing platforms do not always utilize the latest 3D graphics technologies. How important is it to use the latest 3D capabilities to balance realism and performance in your games?

Fishlabs: Imagination Technology’s PowerVR is one of the best architectures on the market because its overall texture compression is very good. There are still minor issues with the processing of normal maps, but apart from that, the visual quality of PowerVR-encoded textures is among the best you’re going to find, especially in relation to the file size.

GPU-wise, Adreno and Mali are both quite powerful. The same is also valid for Tegra 2, which supports DXT texture compression that's well-suited for the creation of state-of-the-art visuals in PC or console quality. Let’s wait and see if Tegra 3 will be able to up the ante even further.

Madfinger: There is really no impetus to support the latest graphic techniques. Remember, there is always going to be a lag between standards and actual implementation. We know this from our experience on the desktop, but we have been able to find various different ways to render better graphics.

Mediocre: It is hard to say. However, generally, performance tends to depend more on screen resolution and the graphics driver to some extent, rather than which chip or technology being used. As a disclaimer, we haven't done any side-by-side benchmarks between all of the various SoCs.

Vector Unit: All of our games are somewhat high-end 3D games, and for us fill rate and GPU performance are usually the gating factors. We almost never have issues on the CPU side, even with dual-core or fast single-core devices. Quad-core is great, but what we are really looking for, going forward, is increases in GPU performance.

    tk1138EXACTLYthese mobile games are a joke...they are clearly made for the lowest common denominator of people (the stupid)

    Obviously this is a PC centric website, but a fair amount of "hardcore gamers" seem to miss the point completely. Honestly the term Hardcore Gamer seems to indicate you're not really a gamer at all.

    Games are there to entertain, and to have fun. If I can have fun playing World of Goo on my android phone while running errands with my wife, or play Machinarium on my Playbook while flying to my destination, then at is gaming at it's essence. Honestly the Wii was probably the best and worst thing to happen to gaming. Obviously it brought out alot of shovelware (that otherwise would have targeted another console) but it also showed the world that people don't need serious games, we need fun games. Not everyone wants to compete all the time, they just want something to pass the time, to tell a story.

    There's room in the market for all game types. Hell, I even backed Takedown since I do enjoy a "serious" game occasionally. But claiming that people will stop playing tablet games "once they see what a PC can do" is ignorant. I'm well aware of what a PC can do, and will continue to play games on all my devices, when convenient. I don't need great graphics to have fun, just remember that video games started out with a dot and 2 lines.

    True that HD version is the way, but developers should not charge additional fees for it. Imagine if PC game developers implement this...you pay for the 1024x768 pix version, then when you upgrade your resolution to 1680x1050 pix, do you have to buy the game again?

    tk1138EXACTLYthese mobile games are a joke...they are clearly made for the lowest common denominator of people (the stupid)

    ram1009This is complete BS IMHO. I don't see how anybody can enjoy gaming on such a tiny screen not to mention the lack of processing power and absence of memory required by modern games. It's all wishful thinking by the marketeers. Just something new to sell unsuspecting novices who later find out what a desktop can do and buy what they should have bought in the first place.


    You two are exaggerating by way too much. Mobile gaming isn't for the stupid, not in the least. It's for people who want to game when they are mobile. Desktops are for a completely different market with different goals. Mobile gaming is not about matching PC gaming in quality, it's about cheap, affordable games that can be played when you are mobile. Of course they won't come close to desktop quality. Mobile games are not for the stupid, they are for the mobile. You two are just elitest pricks who don't recognize that your ways of life can't be sustained by everyone else and even if they could, not everyone wants to be like you. If I'm on a train for two hours a day to go between work in a city and my home in a cheaper suburb outside of the city, then wth am I supposed to do? PCs obviously aren't a viable choice here. However, I have my phone on me, so I can use it. Mobile gaming markets are pretty similar to the Game Boys and such, except the smart phones are both for gaming and many other uses.

    Sure, mobile gaming can also be done at the house and such for people who want to do it. It is FAR more affordable than PC or console gaming is, so many more people can do it who would have otherwise been left without any good games at all. Furthermore, games obviously don't need tons of memory if they are written well. For example, the PS3 only has 256MB of GDDR3 VRAM and only 256MB of XDR system RAM and most modern smart phones have at least that much memory, if not even more. Smart phones have more than enough memory for mobile gaming.

    Furthermore, smart phones are approaching the processing power of the PS3 and Xbox 360. Tablets have already matched them with the newest iPad (although I'd wait until a non-Apple tablet/smart phone had such power before buying something like this). Most people simply can't afford or can't justify spending hundreds to thousands of dollars to get high performance gaming systems and games for those systems, especially when they can get a far cheaper phone that is also needed for other things and get the games for less than $10 each (many are free). Sure, they aren't as high quality as some PC games, but it's not like most PC games we see today are nearly as good for the time as we have seen in the past. So many potentially good games have been dumbed down or were just made poorly.

    Sure, we still have some good games, but most of them simply aren't anymore. Sometimes, I'd rather just play an older game nowadays just because they were simply better games, despite not having as much eye candy. Seriously now... Most people need a phone for a variety of reasons (be they convenience or through necessities such as jobs requiring phones and other important reasons). Most people don't really need a computer for anything except internet access. Sure, some people, such as developers, IT, and others need them for their jobs, but most people don't really need them and can do a lot of what needed a PC on a cheap laptop or even on a good smart phone. So, phones are obviously pretty much universally needed by the majority. You can just get a free or a cheap game, or a bunch of them, for the prices of a single PC/console game. They don't even need to be as good... At least smart phone games don't have DRM problems and such that PC games (and possibly console games soon enough) have.

    Though I agree that paying more for an HD version of a game is not the right way moving forward, I do believe HD resolution for gaming is essential. In my opinion, a game with excellent high-resolution graphics will win over a similar game with a lower res graphics. Having that crisp, clean graphics, would say a lot about the quality of the game even before the consumer has a chance to play it. First impressions count.

    Phone & Tablet Reviews - I'm of the opinion, at least (here), there's little point to voicing any constructive point of view. Each platform has their followers and the numbers based on sales are not representative of the folks that post their comments.

    Therefore, whichever platform you like I hope you can 'get' what you like. I do hope that all platforms can make it easier for the developers.

    Though at least we know why they've nothing to do with it. I for one was unaware of the native code restriction. It's good to see they're willing to support Win 8 though.

    What was more interesting is the way they completely avoided talking about anything related to x86. Can't be sure why but i think they've not got much experience at all with the arch.

    ram1009You can always tell when someone is out of logical, focused arguements. They start calling names. "Elitist prick"? What do I care how you spend your 2 hour commute? Next you'll be telling me it's OK to game and drive. Something tells me you're an itard.

    Why would an "itard" avoid buying the new iPad and wait for a non-apple tablet to have that kind of power? When did he indicate that he drives a car at all, let alone proposed that driving while being on a cell phone was acceptable?

    You called touchscreen gamers "unsuspecting novices", got called out on it, then called another user an "itard". You might want to read the first line of your post again aloud.

    Yeah... That big post of mine full of logical arguments must mean that I'm out of logical arguments. Me using a hypothetical situation that is fairly common for many people must mean that I do it too, mustn't it? Me saying that a lot of people like to have something to do when they are on a train must mean that I support gaming while driving a car, mustn't it? Me specifically saying that I refuse to buy Apple hardware must make me an Apple fan, mustn't it? Looks like you're the one without any logical arguments. You just resorted to insulting me after I called you out on your ridiculous comment. It showed obvious signs of being an elitest prick, so that's what I said. My comment doesn't imply that I support Apple nor that I even support Apple's products at all, so your insult didn't even make much sense at all.

    I enjoyed reading this. Thanks a bunch for the interview! As an amateur Windows Phone developer I appreciate being able to hear what other devs are saying (by amateur, I mean that I've only done silverlight and c#, not XNA (games) or C++, which I can't even read! haha). The questions that you asked were good and relevant and I'm glad that you did include windows phone as part of the question set; I may have a bias, though. Great article!

    My 2 cents Mobile phone gaming (smartphones/tablets) will replace devices such as the DS and PSVita and so on. I don't think it will ever replace consoles or PC gaming. why do I need a separate mobile gaming system when I have a phone that can do it.

    Mihai CAndrew Ku, your shameful promotion of Windows Phone was embarasing. The developers have nothing to do with it, and you kept bringing it up over and over again.

    I actually thought the Windows Phone thing was quite interesting. I was recently in a group that coded a game in XNA for our CS class. The class is mainly taught in C and C++, but our Prof let us use XNA and C# for this game project if we so choosed, and it was definitely one of the easiest programming projects we did all semester. We did it too without the majority of us ever seeing C# or coding a game, and it was cake! Plus, porting from the PC to Xbox to Windows Phone is only a matter of changing controls around. So, if you're already in the Microsoft gaming ecosystem, development is super easy. It's insightful to see that the error on Microsoft's part was in the fact that they didn't make porting from other platforms to their own so easy.

    _Pez_I see in the future Smartphones and tablets games over consoles. console's future is getting dark


    From the same generation, a console can always have several times the processing power of a smart phone or tablet. The iPad 3 is the first phone/tablet to match PS3/Xbox 360 performance and it came out almost a decade after they did. If a console were released with modern hardware right now, it could be FAR faster than any smart phone or tablet simply because it has an always on, high wattage (compared to the mobile devices mentioned) power supply and chips that can use that power to churn out performance far greater than the aforementioned mobile devices.

    Compare a low end desktop to the phones and tablets to get an idea of the difference. A console can often churn out the quality offered by a PC of about 50% to 100% greater cost when they come out, so lets compare, say, a $700 PC to the most recent tablets (how about the newest iPad?).

    The PC could have an i5, Radeon 7850, and 8GB of 1600MHz DDR3. It could play pretty much any game in at least 1080p with the settings more or less maxed out and with some good AA. A console made today could probably do the same for about $350 to $400.

    The tablet? stuck at less than half of the performance at the same (or a greater) cost. Smart phones would fair even worse than the tablet.

    The future of consoles may be getting dark, but for completely different reason than what are shown in this article and your comment. For example, the extreme DRM problems and the fact that people might not be willing to deal with another release cycle this long as well as they have dealt with this one (which isn't very well already).

    The gameplay has to be equally important. Having an aesthetically pleasing game that lacks quality gameplay is just a flashy distraction.
