An anonymous reader writes: Bloomberg reports that Samsung has filed a complaint with the U.S. International Trade Commission asking them to block the import of Nvidia's graphics chips . This is part of Samsung's retaliation for a similar claim filed by Nvidia against Samsung and Qualcomm back in September. Both companies are wielding patents pertaining to the improved operation of graphics chips in cell phones and other mobile devices.

Three-Way Comparison Shows PCs Slaying Consoles In Dragon Age Inquisition 227

Posted by Soulskill
from the as-expected dept.
MojoKid writes: "BioWare's long-awaited Dragon Age Inquisition has dropped for the PS4, Xbox One, and PCs. A comparison of the visuals in key scenes between all three platforms shows that while the PC variant clearly looks the best in multiple areas (as it should), there's evidence of good, intelligent optimization for consoles and PCs alike. After the debacle of Assassin's Creed Unity, Inquisition could provide an important taste of how to do things right. As expected though, when detail levels are increased, the PC still pulls away with the best overall visuals. The Xbox One and PS4 are largely matched, while PC renders of characters have better facial coloring and slightly more detailed textures. The lighting models are also far more detailed on the PC version with the PS4 following behind. The Xbox One, in contrast, is rather muddy. Overall, the PC and PS4 are closest in general detail, with the Xbox One occasionally lagging behind.

NVIDIA SHIELD Tablet Android Lollipop Update Performance Explored 57

Posted by timothy
from the stats-and-figures dept.
MojoKid writes Last week, NVIDIA offered information regarding its Android Lollipop update for the SHIELD Tablet and also revealed a new game bundle for it. This week, NVIDIA gave members of the press early access to the Lollipop update and it will also be rolling out to the general public sometime later today. Some of the changes are subtle, but others are more significant and definitely give the tablet a different look and feel over the original Android KitKat release. Android Lollipop introduces a new "material design" that further flattens out the look of the OS. Google seems to have taken a more minimalist approach as everything from the keyboard to the settings menus have been cleaned up considerably. Many parts of the interface don't have any markings except for the absolute necessities. While the OS definitely feels more fluid and responsive, the default look isn't always better, depending on your personal view. The app tray for example has a plain, white background which looks kind of jarring if you've using a colorful background. And finding the proper touch points for things like a settings menu or clearing notifications isn't always clear. Performance-wise, NVIDIA's Shield Tablet showed significantly better performance on Lollipop for general compute tasks in benchmarks like Mobile XPRT but lagged behind Kit Kat in graphics performance slightly, which could be attributed to driver optimization.

GTK+ Developers Call For Help To Finish Cross-Platform OpenGL Support 89

Posted by timothy
from the gears-spinning dept.
jones_supa writes OpenGL support under GTK is getting into good shape for providing a nice, out-of-the-box experience by default on key platforms for the GTK+ 3.16 / GNOME 3.16 release in March. For a few weeks now within mainline GTK+ has been native OpenGL support and as part of that a new GtkGLArea widget for allowing OpenGL drawing within GTK applications. Since that initial work landed, there's been more GTK+ OpenGL code progressing that right now primarily benefits Linux X11 and Wayland users. While good progress is being made and improvements still ongoing to the GNOME toolkit, GNOME developers are requesting help in ensuring other GTK+ backends can benefit from this OpenGL support. If you are using or planning to use GTK+ 3 on Windows or OS X, and you know how to use OpenGL on those two platforms, please consider helping out the GTK+ developers by implementing the GdkGLContext API using WGL and AppleGL.

An Applied Investigation Into Graphics Card Coil Whine 111

Posted by timothy
from the like-y'do dept.
jones_supa writes We all are aware of various chirping and whining sounds that electronics can produce. Modern graphics cards often suffer from these kind of problems in form of coil whine. But how widespread is it really? Hardware Canucks put 50 new graphics cards side-by-side to compare them solely from the perspective of subjective acoustic disturbance. NVIDIA's reference platforms tended to be quite well behaved, just like their board partners' custom designs. The same can't be said about AMD since their reference R9 290X and R9 290 should be avoided if you're at all concerned about squealing or any other odd noise a GPU can make. However the custom Radeon-branded SKUs should usually be a safe choice. While the amount and intensity of coil whine largely seems to boil down to luck of the draw, at least most board partners are quite friendly regarding their return policies concerning it.

Ubisoft Points Finger At AMD For Assassin's Creed Unity Poor Performance 262

Posted by samzenpus
from the who's-to-blame dept.
MojoKid (1002251) writes "Life is hard when you're a AAA publisher. Last month, Ubisoft blamed weak console hardware for the troubles it had bringing Assassin's Creed Unity up to speed, claiming that it could've hit 100 FPS but for weak console CPUs. Now, in the wake of the game's disastrous launch, the company has changed tactics — suddenly, all of this is AMD's fault. An official company forum post currently reads: "We are aware that the graphics performance of Assassin's Creed Unity on PC may be adversely affected by certain AMD CPU and GPU configurations. This should not affect the vast majority of PC players, but rest assured that AMD and Ubisoft are continuing to work together closely to resolve the issue, and will provide more information as soon as it is available." There are multiple problems with this assessment. First, there's no equivalent Nvidia-centric post on the main forum, and no mention of the fact that if you own an Nvidia card of any vintage but a GTX 970 or 980, you're going to see less-than ideal performance. According to sources, the problem with Assassin's Creed Unity is that the game is issuing tens of thousands of draw calls — up to 50,000 and beyond, in some cases. This is precisely the kind of operation that Mantle and DirectX 12 are designed to handle, but DirectX 11, even 11.2, isn't capable of efficiently processing that many calls at once. It's a fundamental limit of the API and it kicks in harshly in ways that adding more CPU cores simply can't help with.

Tekla Perry writes Stealthy 'cinematic reality' company Magic Leap may be based in Florida--but it's doing a lot of hiring from the Bay Area, scooping up engineers from Pixar, Google, Apple, and Intel--along with a few Willow Garage alums. And it's got openings for many many more. Are all these folks with long-term Silicon Valley roots really going to move to South Florida? Or is Magic Leap getting ready to open up a Silicon Valley research center to house the brain trust it is gathering? Here's what we know about Magic Leap and its technology, who's joining it, and what other kinds of engineers the company aims to hire. Magic Leap has a lot of money to do all that hiring, having just raised more than half a billion dollars, the bulk of it from Google. If you're working in the Bay Area now, would you look forward to a move to Florida, or rather stay where you are?

Major Performance Improvement Discovered For Intel's GPU Linux Driver 96

from the striving-for-parity dept.
An anonymous reader writes: LunarG, on contract with Valve Software, discovered a critical shortcoming with the open-source Intel Linux graphics driver that was handicapping the performance. A special bit wasn't being set by the Linux driver but was by the Windows driver, which when enabled is increasing the Linux performance in many games by now ~20%+, which should allow for a much more competitive showing between Intel OpenGL performance on Windows vs. Linux. However, the patch setting this bit isn't public yet as apparently it's breaking video acceleration in certain cases.

French Health Watchdog: 3D Viewing May Damage Eyesight In Children 99

Posted by timothy
from the this-time-with-feeling-but-not-depth dept.
dryriver (1010635) writes with this clipping from the BBC: A French health watchdog has recommended that children under the age of six should not be allowed access to 3D content. The Agency for Food, Environmental and Occupational Health and Safety (Anses) added that access for those up to the age of 13 should be 'moderate'. It follows research into the possible impact of 3D imaging on still-developing eyes. Few countries currently have guidelines about 3D usage. According to Anses, the process of assimilating a three-dimensional effect requires the eyes to look at images in two different places at the same time before the brain translates it as one image. 'In children, and particularly before the age of six, the health effects of this vergence-accommodation conflict could be much more severe given the active development of the visual system at this time,' it said in a statement.

from the projects-to-admire dept.
jones_supa writes Kubuntu Vivid is the development name for what will be released in April next year as Kubuntu 15.04. The exciting news is that following some discussion and some wavering, the Kubuntu team will be switching to Plasma 5 by default. They claim that it has shown itself as a solid and reliable platform and it's time to show it off to the world. There are some bits which are missing from Plasma 5 which are planned to be filled in over the next six months. As another technical detail, Debian git is now used to store the packaging in a Kubuntu branch, so hopefully it will be easier to share updates.

Tao3D: a New Open-Source Programming Language For Real-Time 3D Animations 158

descubes (35093) writes "Tao3D is a new open-source programming language designed for real-time 3D animations. With it, you can quickly create interactive, data-rich presentations, small applications, proofs of concept, user interface prototypes, and more. The interactivity of the language, combined with its simplicity and graphical aspects, make it ideal to teach programming.

Tao3D also demonstrates a lot of innovation in programming language design. It makes it very easy to create new control structures. Defining if-then-else is literally a couple of lines of code. The syntax to pass pass blocks of code to functions is completely transparent. And it is fully reactive, meaning that it automatically reacts as necessary to external events such as mouse movements or the passage of time.

The source code was just made available under the GNU General Public License v3 on SourceForge [as linked above], GitHub and Gitorious."

The community-based, reverse-engineering Freedreno driver project is finally paying off and gaining critical momentum with Qualcomm now contributing to the driver. QuIC through the Aurora Forum provided Adreno A4xx hardware support to the Freedreno MSM kernel driver.

Alienware's Triangular Area-51 Re-Design With Tri-SLI GeForce GTX 980, Tested 138

Posted by timothy
from the where-are-you-priorities dept.
MojoKid writes Dell's Alienware division recently released a radical redesign of their Area-51 gaming desktop. With 45-degree angled front and rear face plates that are designed to direct control and IO up toward the user, in addition to better directing cool airflow in, while warm airflow is directed up and away from the rear of the chassis, this triangular-shaped machine grabs your attention right away. In testing and benchmarks, the Area-51's new design enables top-end performance with thermal and acoustic profiles that are fairly impressive versus most high-end gaming PC systems. The chassis design is also pretty clean, modular and easily servicable. Base system pricing isn't too bad, starting at $1699 with the ability to dial things way up to an 8-core Haswell-E chip and triple GPU graphics from NVIDIA and AMD. The test system reviewed at HotHardware was powered by a six-core Core i7-5930K chip and three GeForce GTX 980 cards in SLI. As expected, it ripped through the benchmarks, though the price as configured and tested is significantly higher.

Apple A8X IPad Air 2 Processor Packs Triple-Core CPU, Hefty Graphics Punch 130

Posted by samzenpus
from the give-me-the-numbers dept.
MojoKid writes When Apple debuted its A8 SoC, it proved to be a modest tweak of the original A7. Despite packing double the transistors and an improved GPU, the heart of the A8 SoC is the same dual-core Apple "Cyclone" processor tweaked to run at higher clock speeds and with stronger total GPU performance. Given this, many expected that the Apple A8X would be cut from similar cloth — a higher clock speed, perhaps, and a larger GPU, but not much more than that. It appears those projections were wrong. The Apple A8X chip is a triple-core variant of the A8, with a higher clock speed (1.5GHz vs. 1.4GHz), a larger L2 cache (2MB, up from 1MB) and 2GB of external DDR3. It also uses an internal metal heatspreader, which the Apple A8 eschews. All of this points to slightly higher power consumption for the core, but also to dramatically increased performance. The new A8X is a significant power house in multiple types of workloads; in fact, its the top-performing mobile device on Geekbench by a wide margin. Gaming benchmarks are equally impressive. The iPad Air 2 nudges out Nvidia's Shield in GFXBench's Manhattan offscreen test, at 32.4fps to 31 fps. Onscreen favors the NV solution thanks to its lower-resolution screen, but the Nvidia device does take 3DMark Ice Storm Unlimited by a wide margin, clocking in at 30,970 compared to 21,659.

Ask Slashdot: How Do I Make a High-Spec PC Waterproof? 202

from the lots-of-duct-tape dept.
jimwormold writes: I need to build a system for outdoor use, capable of withstanding a high pressure water jet! "Embedded PC," I hear you cry. Well, ideally yes. However, the system does a fair bit of number crunching on a GPU (GTX970) and there don't appear to be any such embedded systems available. The perfect solution will be as small as possible (ideally about 1.5x the size of a motherboard, and the height will be limited to accommodate the graphics card). I'm U.K.- based, so the ambient temperature will range from -5C to 30C, so I presume some sort of active temperature control would be useful.

I found this helpful discussion, but it's 14 years old. Thus, I thought I'd post my question here. Do any of you enlightened Slashdotters have insights to this problem, or know of any products that will help me achieve my goals?

Ubuntu 14.10 Released With Ambitious Name, But Small Changes 110

Posted by timothy
from the I'd-hoped-for-ubiquitous dept.
Ubuntu 14.10, dubbed Utopic Unicorn, has been released today (here are screenshots). PC World says that at first glance "isn't the most exciting update," with not so much as a new default wallpaper — but happily so: it's a stable update in a stable series, and most users will have no pressing need to update to the newest version. In the Ubuntu Next unstable series, though, there are big changes afoot: Along with Mir comes the next version of Ubuntu’s Unity desktop, Unity 8. Mir and the latest version of Unity are already used on Ubuntu Phone, so this is key for Ubuntu's goal of convergent computing — Ubuntu Phone and Ubuntu desktop will use the same display server and desktop shell. Ubuntu Phone is now stable and Ubuntu phones are arriving this year, so a lot of work has gone into this stuff recently. The road ahead looks bumpy however. Ubuntu needs to get graphics drivers supporting Mir properly. The task becomes more complicated when you consider that other Linux distributions — like Fedora — are switching to the Wayland display server instead of Mir. When Ubuntu Desktop Next becomes the standard desktop environment, the changes will be massive indeed. But for today, Utopic Unicorn is all about subtle improvements and slow, steady iteration.

More Eye Candy Coming To Windows 10 209

Posted by timothy
from the sincere-flattery dept.
jones_supa writes Microsoft is expected to release a new build of the Windows 10 Technical Preview in the very near future, according to their own words. The only build so far to be released to the public is 9841 but the next iteration will likely be in the 9860 class of releases. With this new build, Microsoft has polished up the animations that give the OS a more comprehensive feel. When you open a new window, it flies out on to the screen from the icon and when you minimize it, it collapses back in to the icon on the taskbar. It is a slick animation and if you have used OS X, it is similar to the one used to collapse windows back in to the dock. Bah.

Let's organize this thing and take all the fun out of it.
