So, for all the discussion about DirectX 12, the three main desktop GPU vendors, NVIDIA, AMD, and Intel, want to tell OpenGL developers how to tune their applications. Using OpenGL 4.2 and a few cross-vendor extensions, because OpenGL is all about its extensions, a handful of known tricks can reduce driver overhead up to ten-fold and increase performance up to fifteen-fold. The talk is very graphics developer-centric, but it basically describes a series of tricks known to accomplish feats similar to what Mantle and DirectX 12 suggest.
The 130-slide presentation is broken into a few sections, each GPU vendor getting a decent chunk of time. On occasion, they would mention which implementation fairs better with one function call. The main point that they wanted to drive home (since they clearly repeated the slide three times with three different fonts) is that none of this requires a new API. Everything exists and can be implemented right now. The real trick is to know how to not poke the graphics library in the wrong way.
The page also hosts a keynote from the recent Steam Dev Days.
That said, an advantage that I expect from DirectX 12 and Mantle is reduced driver complexity. Since the processors have settled into standards, I expect that drivers will not need to do as much unless the library demands it for legacy reasons. I am not sure how extending OpenGL will affect that benefit, as opposed to just isolating the legacy and building on a solid foundation, but I wonder if these extensions could be just as easy to maintain and optimize. Maybe it is.
Either way, the performance figures do not lie.

Tagged: oculus rift, Oculus, gdc 14, GDC
Last month, we published a news piece stating that Oculus Rift production has been suspended as "certain components" were unavailable. At the time, the company said they are looking for alternate suppliers but do not know how long that will take. The speculation was that the company was simply readying a new version and did not want to cannibalize their sales.
This week, they announced a new version which is available for pre-order and expected to ship in July.
DK2, as it is called, integrates a pair of 960x1080 OLED displays (correction, March 22nd @ 3:15pm: It is technically a single 1080p display that is divided per eye) for higher resolution and lower persistence. Citing Valve's VR research, they claim that the low persistence will reduce motion blur as your eye blends neighboring frames together. In this design, it flickers the image for a short period before going black, and does this at a high enough rate keep your eye fed with light. The higher resolution also prevents the "screen door effect" complained about by the first release. Like their "Crystal Cove" prototype, it also uses an external camera to reduce latency in detecting your movement. All of these should combine to less motion sickness.
I would expect that VR has a long road ahead of it before it becomes a commercial product for the general population, though. There are many legitimate concerns about leaving your users trapped in a sensory deprivation apparatus when Kinect could not even go a couple of days without someone pretending to play volleyball and wrecking their TV with ceiling fan fragments. Still, this company seems to be doing it intelligently: keep afloat on developers and lead users as you work through your prototypes. It is cool, even if it will get significantly better, and people will support its research while getting the best at the time.
DK2 is available for pre-order for $350 and is expected to ship in July.

Game developers, from indie to the gigantic, can now access Unreal Engine 4 with a $19/month subscription (plus 5% of revenue from resulting sales). This is a much different model from UDK, which was free to develop games with their precompiled builds until commercial release, where an upfront fee and 25% royalty is then applied. For Unreal Engine 4, however, this $19 monthly fee also gives you full C++ source code access (which I have wondered about since the announcement that Unrealscript no longer exists).
Of course, the Unreal Engine 3-based UDK is still available (and just recently updated).
This is definitely interesting and, I believe, a response to publishers doubling-down on developing their own engines. EA has basically sworn off engines outside of their own Frostbite and Ingite technologies. Ubisoft has only announced or released three games based on Unreal Engine since 2011; Activision has announced or released seven in that time, three of which were in that first year. Epic Games has always been very friendly to smaller developers and, with the rise of the internet, it is becoming much easier for indie developers to release content through Steam or even their own website. These developers now have a "AAA" engine, which I think almost anyone would agree that Unreal Engine 4 is, with an affordable license (and full source access).
Speaking of full source access, licensees can access the engine at Epic's GitHub. While a top-five publisher might hesitate to share fixes and patches, the army of smaller developers might share and share-alike. This could lead to Unreal Engine 4 acquiring its own features rapidly. Epic highlights their Oculus VR, Linux and Steam OS, and native HTML5 initiatives but, given community support, there could be pushes into unofficial support for Mantle, TrueAudio, or other technologies. Who knows?
A sister announcement, albeit a much smaller one, is that Unreal Engine 4 is now part of NVIDIA's GameWorks initiative. This integrates various NVIDIA SDKs, such as PhysX, into the engine. The press release quote from Tim Sweeney is as follows:
Epic developed Unreal Engine 4 on NVIDIA hardware, and it looks and runs best on GeForce.
Another brief mention is that Unreal Engine 4 will have expanded support for Android.

Tagged: Mantle, gdc 14, GDC, crytek, CRYENGINE
While I do not have too many details otherwise, Crytek and AMD have announced that mainline CRYENGINE will support the Mantle graphics API. CRYENGINE, by Crytek, now sits alongside Frostbite, by Dice, and Nitrous, by Oxide Games, as engines which support that alternative to DirectX and OpenGL. This comes little more than a week after their announcement of native Linux support with their popular engine.
The tape has separate draw calls!
Crytek has been "evaluating" the API for quite some time now, showing interest back at the AMD Developer Summit. Since then, they have apparently made a clear decision on it. It is also not the first time that CRYENGINE has been publicly introduced to Mantle, with Chris Robert's Star Citizen, also powered by the 4th Generation CRYENGINE, having announced support for the graphics API. Of course, there is a large gap between having a licensee do legwork to include an API and having the engine developer provide you supported builds (that would be like saying UnrealEngine 3 supports the original Wii).
Hopefully we will learn more as GDC continues.
Editor's (Ryan) Take:
As the week at GDC has gone on, AMD continues to push forward with Mantle and calls Crytek's implementation of the low level API "a huge endorsement" of the company's direction and vision for the future. Many, including myself, have considered that the pending announcement of DX12 would be a major set back for Mantle but AMD claims that is "short sited" and as more developers come into the Mantle ecosystem it is proof AMD is doing the "right thing."
Here at GDC, AMD told us they have expanded the number of beta Mantle members dramatically with plenty more applications (dozens) in waiting. Obviously this could put a lot of strain on AMD for Mantle support and maintenance but representatives assure us that the major work of building out documentation and development tools is nearly 100% behind them.
If stories like this one over at Semiaccurate are true, and that Microsoft's DirectX 12 will be nearly identical to AMD Mantle, then it makes sense that developers serious about new gaming engines can get a leg up on projects by learning Mantle today. Applying that knowledge to the DX12 API upon its release could speed up development and improve implementation efficiency. From what I am hearing from the few developers willing to even mention DX12, Mantle is much further along in its release (late beta) than DX12 is (early alpha).
AMD indeed was talking with and sharing the development of Mantle with Microsoft "every step of the way" and AMD has stated on several occasions that there were two outcomes with Mantle; it either becomes or inspires a new industry standard in game development. Even if DX12 is more or less a carbon copy of Mantle, forcing NVIDIA to implement that API style with DX12's release, AMD could potentially have the advantage of gaming performance and support between now and Microsoft's DirectX release. That could be as much as a full calendar year from reports we are getting at GDC.

Tagged: Imagination Technologies, gdc 14, wizard, ray tracing
The Tech Report visited Imagination Technologies' booth at GDC where they were showing off a new processor, the Wizard GPU. It is based on the PowerVR Series6XT Rogue graphics processor which is specifically designed to accelerate ray tracing performance, a topic we haven't heard much about lately. They describe the performance as capable of processing 300 million rays and 100 million dynamic triangles per second which translates to 7 to 10 rays per pixel at 720p and 30Hz or 3 to 5 rays a pixel at 1080p and 30Hz. That is not bad, though Imagination Technologies estimates movies display at a rate of 16 to 32 rays per pixel so it may be a while before we see a Ray Tracing slider under Advanced Graphics Options.
"When we visited Imagination Technologies at CES, they were showing off some intriguing hardware that augments their GPUs in order to accelerate ray-traced rendering. Ray tracing is a well-known and high-quality form of rendering that relies on the physical simulation of light rays bouncing around in a scene. Although it's been used in movies and in static scene creation, ray tracing has generally been too computationally intensive to be practical for real-time graphics and gaming. However, Imagination Tech is looking to bring ray-tracing to real-time graphics—in the mobile GPU space, no less—with its new family of Wizard GPUs."

Tagged: WebCL, gdc 14, GDC
The Khronos Group has just ratified the standard for WebCL 1.0. The API is expected to provide a massive performance boost to web applications which are dominated by expensive functions which can be offloaded to parallel processors, such as GPUs and multi-core CPUs. Its definition also allows WebCL to communicate and share buffers between it and WebGL with an extension.
Frequent readers of the site might remember that I have a particular interest in WebCL. Based on OpenCL, it allows web apps to obtain a list of every available compute device and target it for workloads. I have personally executed tasks on an NVIDIA GeForce 670 discrete GPU and other jobs on my Intel HD 4000 iGPU, at the same time, using the WebCL prototype from Tomi Aarnio of Nokia Research. The same is true for users with multiple discrete GPUs installed in their system (even if they are not compatible with Crossfire, SLi, or are from different vendors altogether). This could be very useful for physics, AI, lighting, and other game middleware packages.
Still, browser adoption might be rocky for quite some time. Google, Mozilla, and Opera Software were each involved in the working draft. This leaves both Apple and Microsoft notably absent. Even then, I am not sure how much interest exists within Google, Mozilla, and Opera to take it from a specification to a working feature in their browsers. Some individuals have expressed more faith in WebGL compute shaders than WebCL.
Of course, that can change with just a single "killer app", library, or middleware.
I do expect some resistance from the platform holders, however. Even Google has been pushing back on OpenCL support in Android, in favor of their "Renderscript" abstraction. The performance of a graphics processor is also significant leverage for a native app. There is little, otherwise, that cannot be accomplished with Web standards except a web browser itself (and there is even some non-serious projects for that). If Microsoft can support WebGL, however, there is always hope.
The specification is available at the Khronos website.

Tagged: OpenGL ES, opengl, opencl, gdc 14, GDC, EGL
The Khronos Group has also released their ratified specification for EGL 1.5. This API is at the center of data and event management between other Khronos APIs. This version increases security, interoperability between APIs, and support for many operating systems, including Android and 64-bit Linux.
The headline on the list of changes is the move that EGLImage objects makes, from the realm of extension into EGL 1.5's core functionality, giving developers a reliable method of transferring textures and renderbuffers between graphics contexts and APIs. Second on the list is the increased security around creating a graphics context, primarily designed for WebGL applications which any arbitrary website can become. Further down the list is the EGLSync object which allows further partnership between OpenGL (and OpenGL ES) and OpenCL. The GPU may not need CPU involvement when scheduling between tasks on both APIs.
During the call, the representative also wanted to mention that developers have asked them to bring EGL back to Windows. While it has not happened yet, they have announced that it is a current target.
The EGL 1.5 spec is available at the Khronos website.

Tagged: SYCL, opencl, gdc 14, GDC
To gather community feedback, the provisional specification for SYCL 1.2 has been released by The Khronos Group. SYCL extends itself upon OpenCL with the C++11 standard. This technology is built on another Khronos platform, SPIR, which allows the OpenCL C programming language to be mapped onto LLVM, with its hundreds of compatible languages (and Khronos is careful to note that they intend for anyone to make their own compatible alternative langauge).
In short, SPIR allows many languages which can compile into LLVM to take advantage of OpenCL. SYCL is the specification for creating C++11 libraries and compilers through SPIR.
As stated earlier, Khronos wants anyone to make their own compatible language:
While SYCL is one possible solution for developers, the OpenCL group encourages innovation in programming models for heterogeneous systems, either by building on top of the SPIR™ low-level intermediate representation, leveraging C++ programming techniques through SYCL, using the open source CLU libraries for prototyping, or by developing their own techniques.
SYCL 1.2 supports OpenCL 1.2 and they intend to develop it alongside OpenCL. Future releases are expected to support the latest OpenCL 2.0 specification and keep up with future developments.
The SYCL 1.2 provisional spec is available at the Khronos website.

Tagged: OpenGL ES, opengl, Khronos, gdc 14, GDC
Today, day one of Game Developers Conference 2014, the Khronos Group has officially released the 3.1 specification for OpenGL ES. The main new feature, brought over from OpenGL 4, is the addition of compute shaders. This opens GPGPU functionality to mobile and embedded devices for applications developed in OpenGL ES, especially if the developer does not want to add OpenCL.
The update is backward-compatible with OpenGL ES 2.0 and 3.0 applications, allowing developers to add features, as available, for their existing apps. On the device side, most functionality is expected to be a driver update (in the majority of cases).
OpenGL ES, standing for OpenGL for Embedded Systems but is rarely branded as such, delivers what they consider the most important features from the graphics library to the majority of devices. The Khronos Group has been working toward merging ES with the "full" graphics library over time. The last release, OpenGL ES 3.0, was focused on becoming a direct subset of OpenGL 4.3. This release expands upon the feature-space it occupies.
OpenGL ES also forms the basis for WebGL. The current draft of WebGL 2.0 uses OpenGL ES 3.0 although that was not discussed today. I have heard murmurs (not from Khronos) about some parties pushing for compute shaders in that specification, which this announcement puts us closer to.
The new specification also adds other features, such as the ability to issue a draw without CPU intervention. You could imagine a particle simulation, for instance, that wants to draw the result after its compute shader terminates. Shading is also less rigid, where vertex and fragment shaders do not need to be explicitly linked into a program before they are used. I inquired about the possibility that compute devices could be targetted (for devices with two GPUs) and possibly load balanced, in a similar method to WebCL but no confirmation or denial was provided (although he did mention that it would be interesting for apps that fall somewhere in the middle of OpenGL ES and OpenCL).
The OpenGL ES 3.1 spec is available at the Khronos website.

Tagged: GDC, gdc 14, valve, Steam Controller
Two months ago, Valve presented a new prototype of their Steam Controller with a significantly changed button layout. While the overall shape and two thumbpads remained constant, the touchscreen disappeared and the face buttons more closely resembled something from an Xbox or PlayStation. Another prototype image has been released, ahead of GDC, without many changes.
Valve is still in the iteration process for its controller, however. Ten controllers will be available at GDC, each handmade. This version has been tested internally for some undisclosed amount of time, but this will be the first time that others will give their feedback since the design that was shown at CES. The big unknown is: to what level are they going to respond to feedback? Are we at the stage where it is about button sizing? Or, will it change radically - like to a two-slice toaster case with buttons inside the slots.
GDC is taking place March 17th through the 21st. The expo floor opens on the 19th.

Tagged: gdc 14, crytek, CRYENGINE
The Game Developers Conference (GDC 2014) is getting set for next week in San Francisco and Crytek has an early announcement. Attendees of the event, at presentations and demos in their booth, will see CRYENGINE running natively on Linux. The engine has also been updated to include their enhancements first seen in Ryse, such as "Physically Based Shading".
This announcement gives promise to SteamOS as a viable gaming platform because games which license this engine would have an easier time porting over. That said, Unreal Engine has offered Linux compatibility for licensees, to very limited uptake. Sure, Steam could change that trend because a chicken or an egg could happen at some point -- it does not matter which comes first. Still, this is not the first popular engine to be available for Linux.
Their "Physically Based Shading" system is quite interesting, however. As I understand it, the idea is that developers can make (or maybe use) a library of materials and apply it across any game. This should hopefully reduce the number of artist man-hours to produce a generalized optimal shader. It is much slower to tweak specular highlights and vector math than it is to say "you... are gold... be gold".
The official GDC expo will take place March 19th - 21st but I expect news will flood out from now until then.

Tagged: qualcomm, nvidia, microsoft, Intel, gdc 14, GDC, DirectX 12, amd
The announcement of DirectX 12 has been given a date and time via a blog post on the Microsoft Developer Network (MSDN) blogs. On March 20th at 10:00am (I assume PDT), a few days into the 2014 Game Developers Conference in San Francisco, California, the upcoming specification should be detailed for attendees. Apparently, four GPU manufacturers will also be involved with the announcement: AMD, Intel, NVIDIA, and Qualcomm.
As we reported last week, DirectX 12 is expected to target increased hardware control and decreased CPU overhead for added performance in "cutting-edge 3D graphics" applications. Really, this is the best time for it. Graphics processors are mostly settled into highly-efficient co-processors of parallel data, with some specialized logic for geometry and video tasks. A new specification can relax the needs of video drivers and thus keep the GPU (or GPUs, in Mantle's case) loaded and utilized.
But, to me, the most interesting part of this announcement is the nod to Qualcomm. Microsoft values DirectX as leverage over other x86 and ARM-based operating systems. With Qualcomm, clearly Microsoft believes that either Windows RT or Windows Phone will benefit from the API's next version. While it will probably make PC gamers nervous, mobile platforms will benefit most from reducing CPU overhead, especially if it can be spread out over multiple cores.
Honestly, that is fine by me. As long as Microsoft returns to treating the PC as a first-class citizen, I do not mind them helping mobile, too. We will definitely keep you up to date as we know more.

Also at Mobile World Congres, Lenovo expanded their smartphone portfolio with three additions. Each of these belong to the S-series, although they are only loosely related to one another. North American readers will probably not be able to purchase them, of course; Lenovo's US and Canada websites do not even have a section for smartphones (products like the Vibe Z can be searched directly - but are not available). I take that as a sign.
Anyway, the three phones belong to the S-series but each has a distinct customer in mind. The S860 seems to picture a business user who travels and wants to talk for long periods of time between charges. The similarly named S850 cuts back on RAM and charge capacity, replacing it with aesthetics (colors and an all-glass exterior) and a slightly lower price for users looking for design. Finally, the S660 is the lowest-price of the three, sacrificing things like camera, storage, and screen resolution for users who do not care about any of that.
Let us compare the three phones in a table.
|Display||5.3" 720p||5" 720p||4.7" 960x540|
|Processor (SoC)||MediaTek Quad-Core, 1.3 GHz|
|Dual SIM Card||Yes|
All three phones will be available this year, either at retail or on Lenovo's website. The Lenovo S860 is expected to retail for $349, the S850 should be $269, and the S660 comes in at $229.

Tagged: tablet, MWC 14, MWC, lenovo yoga, Lenovo
At Mobile World Congress 2014, Lenovo has announced the YOGA Tablet 10 HD+. Just last month, we discussed the Yoga Tablet 8 and Yoga Tablet 10 which were presented in October. Those tablets each had a 1280x800 display (even the 10-inch model), both sizes use the same MediaTek MT8125 SoC (Wi-Fi, MT8389 for 3G), and it is 1GB of RAM all-around. Performance was expected to be in the ballpark of a Tegra 3 device.
These are all areas which are bumped for the new YOGA Tablet 10 HD+. The 10.1-inch screen is now at 1080p quality, the SoC is a Qualcomm Snapdragon Quad running at 1.8 GHz, and the RAM is doubled to 2GB. It will running Android 4.3 with an alleged over-the-air (OTA) update to 4.4 KitKat, at some point.
Make sure to bend at the knee and put your hands toge... oh right.
Comparing between the Yoga Ultrabooks, running Windows, and the YOGA Tablets, running Android, would probably not be wise. They are very different designs. The Ultrabooks hinge with an always-attached keyboard while the tablets have a keyboard-less stand. Rather than the Ultrabooks trying to make a keyboard comfortable in tablet usage, the tablets use the small metal hinge to prop up the screen. They key aspect of the cylindrical hinge is its usage as a handle and the volume it provides as battery storage. Ryan found the old versions' 18-hour rated battery life to be fairly accurate, and the new 10 HD+ is rated for the same duration (actually, with a bonus 1000 mAh over the original Tablet 10). Another benefit of its battery location is that, if you are holding the tablet by its hinge, the battery's weight will not have much torque on your fingers.
Of course, now comes the all-important pricing and availability. The Lenovo YOGA Tablet 10 HD+ will be released in April starting at $349. This is higher than the prices of the Tablet 8 and Tablet 10, $199 and $274 respectively, but you also get more for it.

Valve has always been a company based on experimentation and it looks like the Steam Controller is not the lighthouse which guides SteamOS through the fog. Just a week after presenting the prototype at CES, a 3D mockup of a new one makes not-insignificant changes. Gone is the touchscreen and the first revealed button placement. Frankly, just about the only things untouched on the front face are the twin touchpads and the palm grips.
Image Credit: Leszek Godlewski (Twitter)
To fully understand the breadth of the changes, the announcement image is included below. There is basically no discussion about the back so that aspect might be untouched.
The changes were apparently made to assist compatibility with games ported from more traditional input schemes. Looking at the original prototype, there was no obvious mapping from a Sony or Microsoft-based controller to those buttons spread out for both the left and right thumbs to access. The new setup is the typical four face buttons on the right and four more buttons on the left as a surrogate directional pad. If they continue to iterate down this path I hope that the directional pad is more effective than most from the last two generations. It looks like the four directions are separated from one another which does not inspire confidence.
There are two stories which entangle on this one. The first is that Valve is willing to perform rapid iteration until they achieve what they consider a maximum. That is the method to quickest success especially since it allows cross-pollination between designs.
The second is that it also makes the public a little bit nervous.

Tagged: Transformer Book Duet, Intel, CES 2014, CES, asus
Monday, the opening day of CES, was full of keynotes and announcements from Audi to Valve (Yahoo! was the day after). Okay, so that is probably not the complete alphabetical range, but keep reading regardless. The Intel speech had a few surprises including Gabe Newell re-announcing Steam Machines just a couple of hours after his own keynote.
Possibly the most surprising to me was the "Dual OS platforms" announcement. Frankly, I am fine with using BlueStacks for whatever little Android use that my desktop experiences. I did see a demo of the ASUS Transformer Book Duet, however, which was able to switch between Android and Windows 8.1 with the touch of a button and about 3 seconds of black screen. It seems to be more than emulation and it is pretty clearly not rebooting.
To be clear, the following is speculation (and not even confident at that). I am hypothesizing... not reporting. Unfortunately, Intel (and ASUS) have been very silent on the actual implementation as far as I can tell. Since this is clearly branded as "Android and Windows can be friends", it would not surprise me if this was a baked solution for the two platforms and maybe even special hardware.
One possibility is that hardware or software loads both operating systems into memory or hibernation state. In this way, when the user signals their desire for a change, the former operating system is slept (or hibernated) and the processor is then pointed to the others memory space.
Video credit: PCMag
If the above is the case then I hope popular Linux distributions can get their hands on it. Rebooting is far too annoying for me to try out alternative operating systems and virtualization is also too problematic (at least for now). If I can just suspend and switch, especially with native performance on either end, then I will definitely be willing to play around. Honestly, how expensive are RAM and storage these days?
But, if it is user-accessible, then it would be a major consideration for a future upgrade.
The other cute little announcement is Edison, a dual core PC in an SD card form factor. The hope is that this device will power wearable computing and make other devices smarter. It is based on 22nm silicon and even includes WiFi. One use case they presented was a bottle warmer which warms the milk before you even get your child.
Despite the late coverage, it was a very interesting keynote. Ars Technica still has their live blog published if you would like to skim through a play-by-play.

While the world still waits for stock of the custom cooled R9 290X and R9 290 cards from AMD's partners to show up in stores, Gigabyte was showcasing its WindForce models on the floor at CES 2014.
The Gigabyte GV-R929XOC-4GD is an R9 290X graphics cards that includes the company custom designed WindForce, triple fan cooler. The cooler is rated at 450 watts of dissipation, but hopefully you'll never actually be drawing that from this single GPU graphics card. The core clock on this model will be slightly overclocked, going from the stock 1000 MHz to 1040 MHz. Hopefully we'll have a review sample soon so we can verify that it maintains that overclocked clock speed throughout the gaming workloads.
Using the very same cooler is the GV-N78TGHZ-3GD based on the GeForce GTX 780 Ti GPU. In fact, without my tell you which card was which, you'd likely have no way to tell them apart without looking at the PCB more closely. Gigabyte will be setting the base clock on this model at 1085 MHz and the Boost clock at 1150 MHz.
The cards will also include a back plate on the rear of the PCB to help protect the components and ICs while also strengthening the board during shipping general use. Gigabyte says these cards will only carry and MSRP that is $20-50 more than the reference cards so look for each of them this month!

While browsing the Gigabyte suite at CES I came across a very interesting new product from Gigabyte that falls into the Brix family. The Brix Max is a larger version of the Brix SFF chassis (taller) that includes support for four 2.5-in hard drives. Powered by a 4th Generation Intel Core (Haswell) Core i5-4250U processor, this system is aimed towards the NAS market. In particular, those that want tiny NAS devices.
With a total fluid capacity of 1.2 liters (please don't fill your Brix with liquid...), the Brix Max includes a USB flash port, 802.11n Wi-Fi, HDMI output, Gigabit Ethernet and four USB 3.0 ports. Maybe more surprising is the fact that this unit was running Android and marks the first time we have seen a Haswell platform running the OS.
Gigabyte demoed the Brix Max powering a handful of networked devices and providing media content and backup storage for all sorts of other operating system. I am still not sure what kind of software was running on the Android OS to facilitate the NAS functionality but the Max includes the ability to set users, partition different share locations and more. Hopefully we'll be able to get a sample in at the offices to test out and let our readers know how an Android-based NAS can perform.
