| Valve says NVIDIA's the best, Steam and Left 4 Dead for Linux coming along nicely Aug 2nd 2012, 19:20  The godfather of Linux, Linus Torvalds, may think that NVIDIA is "the worst," but Valve respectfully disagrees. The company has been working closely with the manufacturer, as well as AMD and Intel, to boost performance of its hardware under the open source OS. The developer clearly has an interest in getting the best from those companies as it works to port Left 4 Dead 2 and Steam to Linux. That close partnership is already bearing impressive fruit as Valve claims its co-op zombie shooter now performs better on Ubuntu than it does under Windows 7 using a GeForce GTX 680. The first Open GL Linux version managed a measly six frames per second, while the Direct X powered Microsoft one was topping 270. Only a few months later, and Left 4 Dead 2 is hitting 315fps on the 32-bit version of Precise Pangolin, outperforming even the Open GL Windows port which sits at 305fps. Of course, it's relatively well established that Ubuntu has lower overhead and running Direct X only compounds the issue, though, its unparalleled driver support can't be denied. While it's not completely fair to compare performance on a 32-bit OS to a 64-bit one, Valve is proving that gaming on Linux need not be some proof-of-concept exercise. Linus can flip NVIDIA the bird all he wants but, through its work with Valve, it may be doing more to bring Linux to the mainstream than anyone previously has.

Permalink  bit-tech |  Valve | Email this | Comments | | ARM claims new GPU has desktop-class brains, requests OpenCL certificate to prove it Aug 2nd 2012, 18:56  It's been a while since ARM announced its next generation of Mali GPUs, the T604 and T658, but in the semiconductor business silence should never be confused with inactivity. Behind the scenes, the chip designers have been working with Khronos -- that great keeper of open standards -- to ensure the new graphics processors are fully compliant with OpenCL and are therefore able to use their silicon for general compute tasks (AR, photo manipulation, video rendering etc.) as well as for producing pretty visuals. Importantly, ARM isn't settling for the Embedded Profile version of OpenCL that has been "relaxed" for mobile devices, but is instead aiming for the same Full Profile OpenCL 1.1 found in compliant laptop and desktop GPUs. A tall order for a low-power processor, perhaps, but we have a strong feeling that Khronos's certification is just a formality at this point, and that today's news is a harbinger of real, commercial T6xx-powered devices coming before the end of the year. Even the souped-up Mali 400 in the European Galaxy S III can only reign for so long.

Permalink | | Email this | Comments | | Updated Verizon Galaxy Nexus Jelly Bean binaries added to AOSP Aug 2nd 2012, 18:29  CDMA variants are, invariably, the redheaded stepchildren of the Nexus line. That is to say, those units nearly always trail behind their GSM counterparts where updates and official support are concerned. But it appears Google's picking up the pace, having just released the latest Android 4.1.1 Jelly Bean (JRO03H) binaries for Verizon-branded handsets three weeks after welcoming Toro devices back into AOSP. What does this mean for the average user? Not much, since there's no real way to gauge whether or not this signals an imminent carrier-sanctioned OTA rollout, although it does bode well for those prospects. But for rooted users, the new addition is a boon, as it should pave the way for devs to cook up even more stable ROMs for your flashing enjoyment. So, that's the good news. The bad? Well, if you're on the Sprint side of the LTE Nexus divide, your handset's still not invited back to the party -- indefinitely.

Aug 2nd 2012, 18:00  You do know that Parrot makes more than just the AR.Drone, right? It was at CES earlier this year that we first caught a glimpse of -- and subsequently began geeking out about -- the Parrot Zik by Starck. For those unfamiliar, these headphones are jam-packed with enough technologies to make even the geekiest audio lovers smitten. Priced at about $400, they feature Near Field Communication (NFC), Bluetooth connectivity, on-board capacitive touch-control, active noise cancellation, head detection, a jawbone sensor for speech and Parrot's audio-enhancing DSP app for iOS and Android -- not to mention a striking design by the renowned Philippe Starck. This isn't the first time Parrot and Mr. Starck have worked together, but this does mark their debut in the portable audio market (as opposed to home-based speaker systems). In the case of this review, not one, but two Engadget editors spent some time testing the product. So, do they impress? More importantly, are they worth the $400 asking price? You know the drill: meet us after the break where we'll lay it all out. Continue reading Parrot Zik by Starck review: Is $400 worth it for the fanciest, techiest headphones around?
