    In general the term "GI" refers to simulating light bouncing off of scene geometry, so yes it pretty much implies having at least one bounce.

    Fable Legends is using light propagation volumes, which basically injects direct lighting into a camera-aligned grid of sample points and then "propagates" the lighting through 3D space to simulate the light traveling after bouncing off the surface. Tomorrow Children is using voxel cone tracing, which isn't exactly "path tracing" but does compute indirect lighting by tracing cones into a voxel-based representation of the game world. I'm not familiar with with Drive Club is doing, so I can't comment on that.

    Ran into some interesting patents from Microsoft.

    Are you referring to the line about Power Architecture?

    it is validation of the power-architecture. Many things get validated. I think even arm cores for xbox one got validated. Something that gets validated must not get into the final product.

    even NVidia products got validated for xbox one, but they decided to go with AMD hardware after the validation. Validation could mean many things e.g:
    - is something cost-effective or not
    - Does it work or not
    - Can it be done or not
    ...

    Yeah they were planning on including Backwards compatibility on the xbox one early on in it's conception, but they decided to drop it.

    Seems you dont know how SOC design ....
    Validated design is for Final Design
    it wont carrying Xbox One label !!! if it was not validated for Xbox One

    What on Earth Nvidia for Xbox One ?

    Some Validation Process Example

    Very true, we know they had a build-off at one point with a few different silicon options. That was in one of the early videos that they shared I think.

    I don't know how you work, but if I validate something (on work) it doesn't say anything about the final product.
    it is the result of the validation and what's done with the result that counts.
    The result can be "not working" or "working", ..... but someone than decides "that das not fit into budget" (power-budget, $-budget or whatever) so it is validated but not used/canceled or whatever you call it.

    and that with NVidia, yes, that got validated, too (intel also) but because of other aspects (I think not so cost-effective, AMD is really cheap) it was not done. Just lets call it paper-validation (not every validation goes through real silicon) ;)

    The profile shows a lot of PCB and electrical work, it could be a name collision since it uses two generic words.

    You mean he may be referring to power gating or actual consumption?

    Possibly the design and validation of the power delivery system. It's a non-trivial task to supply power to high-power components that can wildly swing in demand very quickly, in part thanks to the power gating and DVFS, along with platform-level switches in mode. There are PCB requirements, active components, one or more microcontrollers, etc.

    There are skills listed that go very well with that kind of design and validation, whereas there are no POWER ISA and x86 ISA flavored electrons.

    I can't fathom the reasoning of people like you. What is your theory? XB1 has extra silicon power inside it but it's just not being used and games are performing worse than PS4?

    Don't worry about replying...

    Dat sekrit saus doh! Seriously are we likely to see this being dredged up until the next gen? The interpretation that he is doing nothing more than power validation is the only one that makes sense, Allandor is absolutely correct that validation != implementation. Validation is often used to answer the question 'could this work' not just 'does this work', I've heard of engineers in my company validating all sorts of exciting things that never make it to the test bench let alone the market.

    People are looking for something that doesn't exist. I think the general population of Xbox owners have generally moved on, the graphical difference being only resolution is appearing to have less of an effect as time goes on. And will likely have less of an effect as more games take on dynamic resolution.

    Technically speaking there is very little left we don't know about Xbox hardware except how the hardware utilized, how it can be optimized and how much of dx12 hardware based features actually exist in Xbox one. And how cloud based processing fits into this picture as an actual proper solution.

    Please don't get derailed by the morons. We're B3D - we're better than that.

    This is extremely new, pre-emptive console switching?

    http://imgur.com/YLC2HNr

    The story from reddit is that this user received this email from Xbox Support. I'll file this under rumor until more people start receiving these, but if this is true, and MS is actively replacing Xbox's that can no longer be upgraded, this is the weirdest thing ever, I've never seen such pre-emptive action.

    edit: so people are saying it is legit. In this reddit users case, their optical disc drive was broken

    edit2: this is both cool and scary at the same time.
