    Fixed powerpacks versus replaceable AA's in controllers *spawn

    Sigh. Why is this even an argument? If you want to use an integrated Li-Ion with microUSB cable charging, just buy the play and charge kit, and forget about AA batteries. If you want a controller docking station to recharge, you can get that too. If you want to use removable generic...

    The hardware in Kinect 2.0 looks to be amazing where is the software to show it off?

    Its still not that simple. You would have to train it for many possible lighting conditions, and different lighting directions. The Kinect 2.0 has a IR illuminator and lighting cancellation that will remove ambient lighting effects, which should make facial recognition a lot more accurate.

    The hardware in Kinect 2.0 looks to be amazing where is the software to show it off?

    Yeah, now try doing it under a wide variety of lighting conditions. The "simple 2 RGB setup" will probably not do so well.

    News & Rumors: Xbox One (codename Durango)

    On 360, the game always comes with a set of drivers and libraries on the disc. Call it the "Game OS". That way driver updates can never screw up an old game, unlike on PC. There is a second "mini-OS" that runs the Xbox "Guide", which is the thing that pops up when you press the big (X) button...

    Xbox One: DirectX 11.1+ AMD GPU , PS4: DirectX 11.2+ AMD GPU what's the difference?

    This is fixed as of Windows 8. Since the implementation detail of things like slists should be hidden from you, as long as you yourself don't go mucking about with the high bits it should all be transparent to your own code...

    Digital Foundry Article Technical Discussion Archive [2013]

    For what it's worth, I have personally benchmarked a new(er) Samsung eMMC 4.5 part at 150 MB/s sustained sequential read performance (1MB I/O size / queue depth 32). This was a real world implementation inside a real world device, running a real world test. Yeah, still not as good as SATA...

    Xbox One (Durango) Technical hardware investigation

    I'd assume that many years into the life of the Xbox One, if a marquee multi-plat title said "we need 7GB or we can't ship on your platform", it would be possible for the Hypervisor to suspend and write out the entire Apps VM to disk, or to shoot a bunch of running apps and shrink the Apps VM on...

    Xbox One (Durango) Technical hardware investigation

    Memory that's not actually storing anything useful is just wasted memory and burning power for no good reason. Any memory that is being used for a read cache can nearly always be reclaimed instantly at the time it needs to be reused for something else. So the policy of the kernel is in...

    esram astrophysics *spin-off*

    The controller and device were capable of being configured to sample on just the up portion of the clock, just the down portion of the clock, or both by setting a few hardware registers. Note that for the thing I was working on, this was designed in from the start. However, it doesn't...

    esram astrophysics *spin-off*

    To be fair, I worked on devices where we had a certain bus controller and storage device that was capable of operating at a variety of clocks, voltages, and both SDR and DDR modes. This was all configurable through software by setting some hardware registers. We ended up picking which...

    xbox1/ps4 - any basic level loading improvements?

    Actually, again speaking from personal experience, there is nothing really wrong with the Windows kernel, power management, and I/O systems. I'm pretty confident the Windows kernel can equal or outperform Android on the same hardware (as of Windows 8 / Windows Phone 8). Windows Phone 8...

    xbox1/ps4 - any basic level loading improvements?

    Having worked on tablet and mobile platforms for a while now, I can honestly say people vastly overestimate the I/O performance on these platforms (and their performance in general -- CPU, memory, GPU). They may be flash based, but high performance they are not. PC SSDs are easily an order of...

    Are the rechargeable Xbox One batteries li ion?

    You have 3 options on Xbox One: 1. You can buy the rechargeable battery pack from MS which is lithium-ion. You do not have to remove the pack from the controller to recharge it. The pack comes with a standard USB cable that connects to the console so you can play and charge at the same time...

    Are the rechargeable Xbox One batteries li ion?

    How on earth is Microsoft giving you a choice of: a. lithium-ion batteries (in their power pack kit) b. normal AAs (dirt cheap at Costco) c. any AA rechargeable batteries you care to use (enloops, whatever) a bad thing?! I'd much rather have the choice of using bog-standard AAs in a...

    Xbox One (Durango) Technical hardware investigation

    133gb/s while alpha blending makes some sense if they figured out some way to overlap reads and writes on the esram. To do an alpha blend you need to read pixel a, read pixel b, and write pixel a+b. That's 3 memory ops (two reads one write) Suppose you can overlap the write for a+b with...
