Microsoft digs deep into Windows 8's hardware graphics boost, says fast just isn't slick enough
While Microsoft has been exploring the sensory experiences that will go into Windows 8, like sight and touch, there's only one thing that many enthusiasts care about: speed. To their delight, Redmond has just devoted one of its pre-release blog posts to showing just how much faster its hardware graphics acceleration will be in a Metro-focused universe. The goal is a hiccup-free 60Hz frame rate, and virtually everything in Windows 8 centers on that ambition. Baked-in transition effects, optimized geometry and even improved font rendering give modern computers a huge jump in performance versus Windows 7. Microsoft is just as keen to expose that power, as well: Direct3D 11.1 is now the root of all video acceleration in the pipeline, making it both easier and faster to mix 2D and 3D. All told, Windows 8 promises to get responsiveness freaks and benchmark lovers all hot and bothered. If either label describes you, the source link might satiate your lust until October 26th.
Chrome hits version 18, improves graphics performance
The big one-eight. Another few months and another version of the Google browser is now up for grabs. With GPU-accelerated Canvas 2D now enabled, you can expect to see even smoother interactions with games and other media-heavy content. WebGL also gets a look-in with a new software-based addition that should help older computers access simple 3D web content. Anyone that's already furnished with Chrome should get auto-updated to the latest version today, while anyone now left with no excuses not to sample the web browser can hit up the download at the source.
WebCL scores first demos, GPU accelerated apps headed to your browser
Look, WebGL is great and everything but, in the era of general-purpose GPU computing, we know our 3D chips are capable of much more than just pushing pixels. WebCL is a new standard that brings OpenCL processing to the browser, leveraging the power of your graphics card to perform complex computations. Samsung and Nokia have both released prototype plug-ins, with Sammy's running exclusively in Safari on OS X using NVIDIA chips and Nokia focusing on the 32-bit Windows version of Firefox 4 and AMD GPUs. At the moment, the young technology doesn't offer much to the average user, but demos (after the break) show just how much faster OpenCL can be than traditional JavaScript -- more than 10-times quicker on some tests. Let the countdown to Folding@Home the Web App begin -- we're starting a pool now.
Cray XK6 supercomputer smashes petaflop record, humbly calls itself a 'general-purpose' machine
Sure, IBM's ten petaflop supercomputer may sound impressive, but Cray can do you five better -- the outfit just announced the Cray XK6, an upgradable, hybrid supercomputing system capable of more than 50 petaflops of computational muscle. Powered by Cray's Gemini interconnect, AMD Opteron 6200 processors, and NVIDIA Tesla 20-Series GPUs, the XK6 system blends x86 and GPU environments with the firm's own flavor of Linux. The folks at Cray won't resort to bragging, however -- they're humbly declaring the machine to be the first "general-purpose supercomputer based on GPU technology," and not, as they put it, a stunt to place high on any Top 500 lists. Suggestive, aren't they? Check out the unassuming press release after the break.
Firefox 4 to be released on March 22nd, download statisticians ready their calculators
Having kicked out a release candidate on March 9th, Mozilla now feels confident enough in version 4 of its well loved Firefox browser and has set a date for its final release: March 22nd. That's next Tuesday, if you're calendar-shy, and a download is penciled in for availability at around 7AM Pacific Time. Mind you, Mozilla believes its RC1 build, already available on Windows, Mac and Linux, will likely be the final version put up in a few days' time -- the team is just monitoring the code and performing last-minute checks to ensure there are no massive, world-ending bugs that haven't been spotted yet. So that basically means you can risk it now and get your GPU-accelerated web future started early, or you can wait until it's official on Tuesday and be part of Mozilla's next attempt at breaking the downloads record.

ElcomSoft turns your laptop into a one-touch WiFi cracking system
It's been a few years since we checked in with Elcomsoft's Wireless Security Auditor WiFi cracking software. As you'd expect, things have become easier, much easier. Elcomsoft now has an all-in-one solution that will locate wireless networks, intercept data packets, and crack WAP/WPA2 PSK passwords from any modern laptop with a discrete ATI AMD or NVIDIA graphics card. Here's the quote IT nerds will surely we love: Today, ElcomSoft is integrating a wireless sniffer into Elcomsoft Wireless Security Auditor. The integrated sniffer turns Elcomsoft Wireless Security Auditor into a one-button, all-in-one solution ready to be used by corporate security officers without specific experience in information security. Call us crazy, but if you're a C-level security officer with no specific information security experience then maybe you shouldn't be sniffing people's data packets. Then again, we're sure ElcomSoft will happily sell their $1,199 pro software or $399 standard edition to any hacker willing to pay, white hat or not.
PowerDVD 10 Ultra 3D Mark II update finally adds 3D Blu-ray support
If you're one of the 2 people who have lost sleep anticipating the Mark II update to Power DVD 10 after our previous post, it's time to relax. Support for 3D Blu-ray playback has officially been added and it's even certified by the Blu-ray Disc Association - a first for software players. To sweeten the pot, a new "Enhanced" version of TrueTheater 3D can now upconvert DVDs or just regular video files with basic 3D effects thanks to optimized GPU hardware acceleration or a high end CPU -- that is if you're willing to submit your eyes to watching it. Coinciding with this release, the company's free BD & 3D Advisor software has also been updated to help users assess what aspects of the Mark II's smorgasbord of video playback / upscaling updates their computer can handle. So if your machine has the hardware and you've been dying for more 3D content -- Blu-ray or otherwise -- consider your wish granted.
Adobe's Flash Player 'Gala' OS X preview tested: results may vary
Gala1 Flash 101 2.40GHz Core i5, NVIDIA GeForce GT 330M 256MB2 Safari 4.0.5 95.4 - 152.8 74.2 - 123.5 Firefox 3.6.4 83.5 - 148.4 89.4 - 130.5 2.66GHz Core i7, NVIDIA GeForce GT 330M 512MB2 Safari 4.0.5 59 - 64 96 - 132 Firefox 3.6.4 69 - 79 111 - 140 So we just put a few minutes aside to put Adobe's new "Gala" build of Flash 10.1 through its paces on our latest-generation Core i5 and i7 15-inch MacBook Pros here, and the results are a little confusing to say the least. On our i7 equipped with the high-res display and 512MB GeForce GT 330M, processor utilization playing a 1080p sample video on YouTube dropped by a third to a half on average -- not bad -- with Safari 4.0.5 besting Firefox 3.6.4 by a smidge. Our i5 saw strangely different numbers, though, with Gala actually increasing the load on the CPU by as much as about 20 percent. Adobe is quick to note that this is nothing more than a rough preview release; Apple just unlocked access to the necessary hardware a few days ago, after all, and we're sure the company still has plenty of optimization to do. Ultimately, if our i7 figures are realistic, it should make high-def Hulu a decidedly less drama-packed experience down the road. Notes: 1 Performance measured by processor utilization (note that numbers greater than 100 are possible on multi-core machines). 2 15.4-inch high resolution display, 256GB SSD, 4GB RAM
Apple Technical Note TN2267: an opening for GPU-accelerated Flash?
There couldn't possibly be any less fanfare from Apple on this, but the company's recently released Technical Note TN2267 for OS X 10.6.3 might just be the GPU-sized opening that Adobe and, consequently, Flash users have been waiting for. Here's the key bit: The Video Decode Acceleration framework is a C programming interface providing low-level access to the H.264 decoding capabilities of compatible GPUs such as the NVIDIA GeForce 9400M, GeForce 320M or GeForce GT 330M. It is intended for use by advanced developers who specifically need hardware accelerated decode of video frames. Now, we're not exactly "advanced developers," but it seems pretty clear that this is designed to give developers access to some inner workings of OS X that have previously been restricted to Apple itself -- access that has been evident in Flash tests that show it performs much better in instances where it can access a computer's GPU. No word from Adobe on this just yet, but we've got to guess they've already taken notice.
IE9 demoed on Ion-based Eee PC with full GPU acceleration
Although we were a little more focused on Windows Phone 7 Series when we went to MIX 10, Microsoft's other big announcement at the conference was Internet Explorer 9, which offers HTML5 support and support for GPU acceleration throughout the browsing experience. We saw a few demos of the system in action at MIX, but this video from NVIDIA does a little better job showing how helpful that extra GPU boost can be -- IE9 running on the Ion 2-based Eee PC 1201PN smokes a regular Atom-based netbook across a suite of tests. What that's going to mean for battery life is up in the air, especially since the GPU on an Optimus system like the 1201PN kicks in automatically, but it's pretty cool to see a netbook browsing the web at almost desktop-like speeds. Check the video after the break.
HTML5 vs. Flash comparison finds a few surprises, settles few debates
Think we'd all be better off if HTML5 could somehow instantly replace Flash overnight? Not necessarily, according to a set of comparisons from Jan Ozer of the Streaming Learning Center website, which found that while HTML5 did come out ahead in many respects, it wasn't exactly a clear winner. The tests weren't completely scientific, but they did find that HTML5 clearly performed better than Flash 10 or 10.1 in Safari on a Mac, although the differences were less clear cut in Google Chrome or Firefox. On the other hand, Flash more than held its own on Windows, and Flash Player 10.1 was actually 58% more efficient than HTML5 in Google Chrome on the Windows system tested. As you may have deduced, one of the big factors accounting for that discrepancy is that Flash is able to take advantage of GPU hardware acceleration in Windows, while Adobe is effectively cut out of the loop on Mac -- something it has complained about quite publicly. According to Ozer, the differences between HTML5 and Flash playback on a Mac could be virtually eliminated if Flash could make use of GPU acceleration. Hit up the link below for all the numbers. Update: Mike Chambers has performed some additional tests that he says shows that "does not perform consistently worse on Mac than on Windows." Check out the complete results here.
Internet Explorer 9 to sport GPU acceleration and HTML5 support
Even if you don't have a favored fighter in the browser wars, you have to admit Microsoft's Internet Explorer has been looking mighty unfit over the last few years. Younger and fitter contenders like Mozilla's Firefox and Google's Chrome have arguably overtaken the old stalwart, and now Microsoft is making some much-needed noise about fighting back. The software giant has been giving developers and curious journalists a very early peek into its IE 9 progress at PDC, with its stated ambitions including faster Javascript (see table above), HTML5 support, and hardware acceleration for web content. By harnessing DirectX and your graphics processor, the new browser will offer improvements in text readability and video performance, as well as taking some of the load off the CPU. Development has only just got under way, mind you, so there's still plenty of time to screw it all up. Or make it awesome.
Adobe's Flash Player 10.1 beta GPU acceleration tested, documented
We know you don't actually care about 99 percent of the contents of the latest Flash Player update. What you really want to know is whether those new 1080p YouTube streams will run smoothly on your machine thanks to the newly implemented graphics card video acceleration. AnandTech has come to our collective aid on that one, with an extensive testing roundup of some of the more popular desktop and mobile GPU solutions. NVIDIA's ION scored top marks, with "almost perfect" Hulu streaming (see table above), though Anand and crew encountered some issues with ATI's chips and Intel's integrated GMA 4500 MHD, which they attribute to the new Flash Player's beta status. On the OS front, although Linux and Mac OS are not yet on the official hardware acceleration beneficiary list, the wily testers found marked improvements in performance under OS X. It seems, then, that Adobe has made good on its partnership with NVIDIA, and made ION netbooks all the more scrumptious in the process, while throwing a bone to the Mac crowd, but leaving the majority of users exercising the virtue of patience until the finalized non-beta Player starts making the rounds in a couple of months.

Windows 7 to feature GPU acceleration like Apple's Snow Leopard?
A first true glimpse of Windows 7, Microsoft's Vista successor, is T minus 1 day and counting. So far we know very little. Oh sure, it supports multi-touch and takes 1,000 engineers to code but the real details will emerge from Tuesday's kickoff to the PDC 2008 developer conference. As detailed by TG Daily, the PDC track notes dedicate 22 of the 155 tracks to Windows 7 with 2 further dedicated to GPU acceleration under the titles, "Unlocking the GPU with Direct3D," and "Writing Your Application to Shine on Modern Graphics Hardware." Interesting times given Apple's announced OS X Snow Leopard support for OpenCL GPU acceleration in partnership with new best buds, Nvidia, and Intel planning to kill off the GPU entirely. Somebody has to be wrong.[Thanks, Jeelz]
