Motorola Atrix 4G Android 4.0 ROM gains hardware acceleration

February 15th, 2012

The Motorola Atrix was released last year by AT&T and since then it has been one of my favorite Android phones. As a matter of fact, I still use it as my daily phone. Our friends at BriefMobile are reporting that the Android 4.0 ROM for the Atrix now has hardware acceleration which means that apps and graphics will run smoother than usual.

I haven’t had a chance to to play around with the latest ICS ROMs but I am definitely giving this a shot. Atrix 4G devices running on leaked ICS builds now have working front and rear cameras, face unlock and even Google Chrome. This sounds very promising for all of us Atrix owners. Don’t expect this ROM to be flawless, there are still many bugs that need to be addressed. It shouldn’t take long until we see a stable ICS build and let’s not forget to thank our fellow Android developers!

Chrome Beta Release With Improved Hardware Acceleration

February 13th, 2012

Google has released the next beta version of the Chrome browser, a day after releasing Google Chrome 17 Stable. Chrome 18 Beta supports GPU accelerated 2D Canvas and 3D contents on older GPUs that were not supported by the browser until now.

The new version introduces GPU accelerated 2D Canvas on Mac and Windows versions of the browser, which according to Google should improve the performance of 2D browser apps and games using the HTML5 technology noticeably.

Chrome users can open the internal page chrome://gpu to check their computer’s graphics feature status. The page lists five features and their hardware acceleration status.

The Swiftshader software 3D rendering technology has been licensed by Google and implemented into the Google Chrome Beta browser to improve the performance of 3D contents on older graphics processing units that do not support GPU based hardware acceleration. While not performing as well as GPU based acceleration, it should boost the performance on systems that were unsupported until now.

At the same time, we recognize that many people with older GPUs and graphics drivers have not been able to experience the rich content provided by technologies such as WebGL. Chrome is now able to display 3D content via SwiftShader, a software rasterizer we licensed from TransGaming, Inc. Although SwiftShader won’t perform as well as a real GPU, it will be an improvement for many of our users on older operating systems such as Windows XP.

The Swiftshader software rasterizer will automatically take over on systems that do not support gpu hardware acceleration. Chrome users who would like to see performance information can start the browser with the following two flags:

* –blacklist-accelerated-compositing
* –blacklist-webgl

Chrome will then download Swiftshader components to the computer to make them available. This can take a few minutes. Some users have even reported that the process is stuck on their system, with no option to get the components to download properly. You can remove the flags later on.

Chrome Beta users should have received the update to version 18 by now. Interested users who want to download the beta version can do so at the Beta channel over at the Google website.

Firefox 4: no full hardware acceleration for Linux

January 17th, 2011

On Friday, the ninth beta version of Firefox 4 was published. On the official Mozilla blog numerous major functions were pointed out at the same time hardware acceleration was announced.

The director of Product Platform Management, Christopher Blizzard emphasised that Firefox 4 supports complete hardware acceleration under Windows 7 and Windows Vista via a combination of Direct2D, DirectX 9 and DirectX 10. While IE9 wont be available to the Windows XP operating system, hardware acceleration is something that is being looked at for certain operations (DirectX 9) in Firefox. For Mac OS X, hardware acceleration is supported by OpenGL, qualified as excellent.

Strangely, Christopher Blizzard didn’t mince his words when talking about Linux, with questions being raised after comments were left on user community sites, with Boris Zbarsky, a developer at Mozilla answering. “We have tried to activate OpenGL for Linux, and we have discovered that most of the Linux drivers are full of bugs which mean that we have had to disable the service for the moment”. Adding that support for WebGL (for 3D Web) had also been disabled for most Linux drivers (this support is assured by Direct3D in Windows).

For Linux, hardware acceleration will be done by composition (via OpenGL) which creates some issues. Hardware acceleration for content provided XRender works well and effectively, “if your drivers are decent, you will have something similar to Direct2D”, states Boris Zbarsky, who also used this opportunity to request help from X.Org developers.

As for full hardware acceleration under Linux for Firefox 4, Mozilla’s developers have nevertheless managed to have a stable environment with Nvidia proprietary drivers.

Hardware acceleration for Moonlight

November 25th, 2010

Moonlight, the free Mono-based Silverlight clone for Linux, can now use the graphics card hardware to render 3D effects and play back videos. In his announcement of the feature, the chief developer for Mono products, Miguel de Icaza, also points out that Moonlight apparently accelerates all pixel shaders, while Microsoft’s Silverlight only accelerates some of them. The software can reportedly accelerate the rendering of surfaces by pre-caching graphics card contents.

Users interested in trying out the driver can find the code on the GitHub project hosting platform. The driver’s developer, David Reveman, explains the possibilities of the hardware acceleration feature in two YouTube videos. The acceleration allows 29 to 35 frames per second to be rendered both in Linux and Windows, compared with 2 to 9 frames without the driver. When the feature will be integrated into Moonlight is yet unclear.

IE9 beta gets updated with better hardware acceleration, JavaScript and CSS 3 support

October 31st, 2010

The official release of Microsoft’s next-gen browser Internet Explorer 9 is still a few months away at the very least, but that’s not stopping the big Em Ess from rolling out new features, as a new pre-release “platform preview” released on Thursday makes amply clear.

Internet Explorer 9 has already vastly expanded IE’s support for evolving, next-gen web standards like HTML5, CSS 3 and WOFF, and users who are already testing the preview clearly feel that it is a major step forward for a browser which has all-too-often been synonymous with clumsy rendering and bad security: Microsoft brags that the beta release has already been downloaded ten million times since its release six weeks ago.

The latest pre-release platform preview bring support for CSS 3’s 2D transforms to the browser, as well as improvements in IE9’s hardware acceleration, font rendering and Javascript technology.

One thing’s for sure about IE9: no matter how you feel about previous Microsoft browsers, the pressure put on IE by the likes of WebKit, Firefox and Chrome has compelled Microsoft to develop their most standardized and well tested browser yet. Let’s hope that IE9 can finally erase the bad taste that IE6 left in everyone’s mouths.

IE9 Alone in full hardware acceleration

September 10th, 2010

In case you missed it, earlier this week Mozilla announced that Firefox 4 (beta 5) will include hardware acceleration, mostly likely to combat the announcement in a few days regarding Microsoft’s Internet Explorer 9, which will also have hardware acceleration.

So, which is better? If you read the msdn blog, you’ll find out that Microsoft believes it has the superior browser technology because they use “full hardware acceleration” as opposed to “partial hardware acceleration. In their own words.

With IE9, developers have a fully-hardware accelerated display pipeline that runs from their markup to the screen. Based on their blog posts, the hardware-accelerated implementations of other browsers generally accelerate one phase or the other, but not yet both. Delivering full hardware acceleration, on by default, is an architectural undertaking. When there is a desire to run across multiple platforms, developers introduce abstraction layers and inevitably make tradeoffs which ultimately impact performance and reduce the ability of a browser to achieve ‘native’ performance. Getting the full value of the GPU is extremely challenging and writing to intermediate layers and libraries instead of an operating system’s native support makes it even harder. Windows’ DirectX long legacy of powering of the most intensive 3D games has made DirectX the highest performance GPU-based rendering system available.

When you run other browsers that support hardware acceleration, you’ll notice that the performance on some of the examples from the IE Test Drive site is comparable to IE9 yet performance on other examples isn’t. The differences reflect the gap between full and partial hardware acceleration. As IE supports new, emerging Web standards, those implementations will also be fully hardware accelerated.

Hardware acceleration of HTML5 video is a great example. At MIX10, we showed the advantage of using hardware for video. In March, IE9 played two HD-encoded, 720p videos on a netbook using very little of the CPU while another browser maxed out the CPU while dropping frames playing only one of the videos. Because of full hardware acceleration of the entire pipeline, you experience great performance playing these videos while moving them around the page and styling and compositing them with opacity, using web standard markup.

I’ll leave the technical jargon up to you to decide, but it is worth noting that Firefox has had hardware acceleration since last year. That being said, they have yet to incorporate “full hardware acceleration” to date. Firefox Beta 4 included acceleration, while beta 5 had it turned on by default as long as you were on a computer running DX10 or greater.

In the race to produce the latest and greatest browser, it will be the browser that brings the most to the table in a fast and secure way. A decent user interface doesn’t hurt either.

Firefox 3.6 likely the last for PowerPC Macs

August 25th, 2010

The current version of Firefox will likely be the end of the road for people using PowerPC Macs.A final decision will be based on usage data that’s better than what Mozilla possesses right now, but technical difficulties raised by Firefox 4 improvements mean at a minimum that it’s a strong possibility only Intel-based Macs will be able to run the new browser.I am gathering data on the number of PPC users we have, but the likely outcome is that we will not be supporting PPC [PowerPC] for Firefox 4,” said Mike Beltzner, Mozilla’s director of Firefox,.

Major changes are a fact of life in the computing industry, but it’s never easy to decide when users of older technology should no longer be supported. Keeping new software compatible with old hardware–and conversely, making sure new hardware can run old software–can be an expensive proposition when there are few users of the older technology left.

But Mozilla’s Firefox now is used by hundreds of millions of people, and even a small fraction of them can be a large number in absolute terms. It’s a plight of widely used software; for comparison, Microsoft has extended the lifespan of Windows XP several times beyond its original plans.Dropping support for older machines, of course, can make those with the machines angry. Mozilla faced disgruntlement when it decided to cut off Firefox support for Mac OS X 10.4 after version 3.6. Using an old browser also exposes people to security risks, though Mozilla maintains older Firefox incarnations for a time after new versions supplant them.

The writing has been on the wall for PowerPC Macs for more than five years. Apple announced in June 2005 it would move to Intel processors instead of the PowerPC models built by IBM and Motorola. The two processor families use different instruction sets, so programs written for one don’t run on the other without significant work
