Your Android games are getting a software speed boost
iPhone users have low-level Metal code to speed up games and other visually intensive apps, but what if you're an Android fan? Don't worry, you'll get your boost soon. Google has announced that Android will soon support Vulkan, an open graphics standard that cuts a lot of the computing overhead and gives apps more direct control over video hardware. It's not as easy to work with as OpenGL, but it should let developers wring more performance out of your phone's processor. That could prove very important when you'd otherwise struggle to run a game on a lower-end phone, or want to get pretty, high-detail graphics on a shiny new flagship. It'll be a while before Vulkan for Android is ready -- the standard itself isn't available, let alone Google's implementation of it -- but it should be worth the wait if your Android devices double as game consoles.
Super-efficient 'Vulkan' leaves your games more graphics power
Psst: the games you play might not look as good (or run as smoothly) as they could. In many cases, the overhead from graphics standards gets in the way -- Apple went so far as to develop its own technology just to make sure that iPhones and iPads could live up to their potential. That bottleneck may not exist for much longer, however. The alliance behind the OpenGL video standard has given a sneak peek at Vulkan, an open standard that lets app writers take direct control of graphics chips and wring out extra performance on many devices, whether it's your phone or a hot rod gaming PC. The software isn't a magic bullet (developers still have to make good use of it), but it could easily lead to richer visuals and smoother frame rates without demanding beefier hardware.
OpenCL 2.0 provisional spec gets outlined, OpenGL 4.4 released
SIGGRAPH has only just begun, but the Khronos Group is already giving folks of the graphics programming persuasion some fresh APIs to talk about. Yesterday marked the release of the OpenCL 2.0 provisional specification, and it's boasting an Android installable client driver extension, along with improvements to image handling, shared virtual memory and more. It's expected that the new version of OpenCL will be finalized in six month's time, and feedback regarding the changes are being welcomed. The fresh OpenGL 4.4 spec revamps everything from shaders to asynchronous queries while keeping full backwards compatibility, and includes additional functions to make porting Direct3D apps a smoother process. If parallel programming and cross-platform graphics are your thing, hit the break for the full feature breakdown in the press releases.
OpenGL ES 3.0 and OpenGL 4.3 squeeze textures to the limit, bring OpenVL along for the ride
Mobile graphics are clearly setting the agenda at SIGGRAPH this year -- ARM's Mali T600-series parts have just been chased up by a new Khronos Group standard that will likely keep those future video cores well-fed. OpenGL ES 3.0 represents a big leap in textures, introducing "guaranteed support" for more advanced texture effects as well as a new version of ASTC compression that further shrinks texture footprints without a conspicuous visual hit. OpenVL is also coming to give augmented reality apps their own standard. Don't worry, desktop users still get some love through OpenGL 4.3: it adds the new ASTC tricks, new visual effects (think blur) and support for compute shaders without always needing to use OpenCL. All of the new standards promise a bright future in graphics for those living outside of Microsoft's Direct3D universe, although we'd advise being patient: there won't be a full Open GL ES 3.0 testing suite for as long as six months, and any next-generation phones or tablets will still need the graphics hardware to match.
OpenGL 4.0 arrives, brings more opportunities for general purpose GPU action
What's a Game Developers Conference without some sweet new tools for developers to sink their teeth into? Khronos Group, the association behind OpenGL, has today announced the fourth generation of its cross-platform API spec, which takes up the mantle of offering a viable competitor to Microsoft's DirectX 11. The latest release includes two new shader stages for offloading geometry tessellation from the CPU to the GPU, as well as tighter integration with OpenCL to allow the graphics card to take up yet more duties off the typically overworked processor -- both useful additions in light of NVIDIA's newfound love affair with tessellation and supposed leaning toward general purpose GPU design in the Fermi chips coming this month. Lest you don't care that much about desktop gaming, OpenGL ES (Embedded Systems, a mobile offshoot of OpenGL) is the graphics standard on "virtually every shipping smart phone," meaning that whatever ripples start on the desktop front will be landing as waves on your next superphone. If that holds true, we can look forward to more involvement from our graphics chips beyond their usual 3D duties and into spheres we tend to care about -- such as video acceleration. Now you care, don't ya?
AMD achieves Open GL ES 2.0 compliance, brings Xbox 360 graphics to mobile platform
A few months ago, AMD promised Xbox 360 graphics on handhelds, and as of today it's delivered on the concept. AMD announced it has achieved Open GL ES 2.0 mobile graphics technology compliance with hardware that cranks out the same AMD Unified Shader Architecture as the Microsoft gaming console. The new graphics standard will no doubt butt heads with NVIDIA's Tegra platform, which also promises serious mobile graphics. Meanwhile, AMD's comparison of their new certification to the Xbox 360 may just be a way to wow us, but we gotta wonder if this could bring some hope to a mobile Xbox 360, whether Microsoft says they're into it or not. Good times.
