    Totally, I'm afraid!

    Well, iirc, Quaz can distinguish easily between 360 and PS3 renders due to certain differences in the rendering process which arise, I believe, due to the fact that one has an ATI gpu and the other has an Nvidia. Since quite some time ago, even before we got to "next-gen", I remember seeing image quality comparisons between ATI and Nvidia cards where the same differences in the rendering were mentioned, I assume we can pretty much know whether something was rendered in either of these gpu families, but not necessarily if it was rendered in a console gpu.

    And these aren't from the 360?

    (screenshot wars coming in the next months... :lol:)

    Are you sure? Horizontal resolution seems to be 1152 (9 steps within 10 pixels).

    not for me, the first is clearly 720p screenshots (but maybe X360 screenshots)

    I'm not arguing against vertical resolution. :) I'm arguing about horizontal one:

    Unless (once again) I'm counting it wrong.

    yes your counting is wrong

    and globally it's not just counting, it's also make good choice of beginning and end step or look the aparence and evolution of step. for exemple a half transparent/blurry step is like a 1/2 step
    if you count 1 step per pixel but the step evolution aspect is successively little more pale/transparent (not just punctuel but evolving) it indicate an upscaling. if you start on a perfect opaque step and finish on a tenth step half transparent, it's not 10 step counting but 10.5 step, it's an indication but the best is to start and finish counting on a step with the same opaque/trasparent/blurry aparence, not compulsorily perfectly sharp steps but at least perfectly similar aspect step
    in all case it's necessary to judge the apparence of step, not just counting

    but in this case no difficulty, just wrong counting
    all steps are the same ratio of blurry aspect with no evolution and 1 pixel par step, it's 1280, not useful to count

    So a blur filter is in effect.

    Well, they sent the pictures along with the press release.

    Maybe Quaz can check the gamersyde pictures, they're much less compressed.

    Edit:

    Also, images and trailer of Beyond Good & Evil 2 here http://www.gamersyde.com/news_6556_en.html. The pictures are in 1080p but seems like, perhaps, photo mode of in-game engine.

    Trailer is awesome.

    If you take the step which is half off the top of your image as the first step (step 0), then you can count 10 steps where the 10th step is the one half off the bottom of the image.

    Therefore your two red lines correspond with the the start step (step 0) and the 10th step away from it (step 10) exactly.

    So count the pixels from step 0 (but not including it) to step 10 (including it), which in that image you'll find is 10 pixels. (The same as your yellow checker, but I count it with one less pixel on the left and one more on the right - it doesn't really matter as long as you include one end and not the other in this method).

    So 10 steps in 10 pixels is 1:1. Hope that helps.

    Yeah, you're right although I think it's easier to understand it by moving the left red line one pixel right (which leads to 9:9). At least it is easier to me as it seems you count edges where I find it easier to count corners. So it's harder for me to visualize level 0. It's the exact opposite mistake to the one I did in the past where I counted pixels properly, but I counted one step more in. There are at least two more classes of mistakes I can make in the future, so stay tuned! ;)

    Thanks guys. :)

    Interesting as the early Home beta I saw last year was definitely 1080p with no AA.

    Which version of Home would be more taxing on the PS3 system, 1080p/-AA or 720p/2AA/Q?

    1080p. You have far more pixels to shade. This is why 720p games are common, and 1080p games aren't ;)
