    DMC4 only looked blurry during motion. These shots look like they are still shots, so maybe its QAA?

    Could well be. Wouldn't this mean that some alternative color space like LogLuv is used to get HDR+QAA working on the PS3? Or are there other ways of achieving that?

    Just a note to say that you really can't judge screen tear from internet video.

    In a 2VBL game like Resi5, a torn frame will only be on screen for 1/60th of a second. Internet video is typically 30 frames a second. Every other frame is thrown away. Therefore either the torn frame will be displayed for twice as long as it should be, or it will not be displayed at all.

    DMC4 looked just about the same

    definitely not the QAA, as the aliasing is more apparent on the PS3.

    I think you misunderstood me. DMC4 used temporal AA so when the camera panned or during action scenes, it would look slightly blurry, but when the player or camera wasn't in motion, it didn't look blurry at all. In those RE5 shots, the camera or player isn't moving yet it still looks slightly blurrier than the 360 shot. Therefore, I don't think they're using the same method as DMC4, but it looks more like QAA to me.

    Even at the static scenes, the PS3 version was slightly blurrier.

    And just take a look at Shiva's arm, you'd clearly see the aliasing effect on the PS3 shot. If the game uses QAA, it should have less aliasing.

    Remember, the 360's textures in DMC4 were actually sharpened making them look too sharp, which caused a shimmering effect that some people didn't like. The PS3 shot doesn't look blurry to me at all, whereas the RE5 PS3 shot does (a little).

    I dunno about RE5 (I'm not the most technical person here) and maybe I'm wrong, but I don't think RE5 is using temporal AA like DMC4.

    Edit: On second view, maybe you're right. That would be the most logical guess as Capcom has used this twice already.

    The texture shimmering on the 360 DMC4 was due to a lack of proper texture filtering, and it's likely to be related to the TMUs, which the PS3 has the upper hand.

    We'll see once the proper capture from grandmaster is available, but at this point it's clear that PS3 version is lesser on the AA, whether it's TAA or just plain blur filter.

    A recent comparison they did show no visible difference in image quality between 360/PS3.

    I'm assuming that the only way to get the demo is to buy a PS3 in Japan? I'd like to take shots, but I can't. The demo discs aren't even being sold on eBay - not even for a hefty ransom.

    Just note that there is not much in fine detail that you can observe from a highly compressed media. To the casual observer, yes, they do appear very similar, but we are interested in those technical differences.

    But I do remember Quaz51 saying that the textures were actually sharpened.

    Hey everyone. I'll be getting the PS3 demo in about a week, so I can provide some shots of the two then. I saw some thread on Neogaf with a guy comparing some FLV based shots to one another, trying to say that the PS3 had worse textures. I guess he thinks the macroblocks on the texturing is part of the game.

    The gametrailers video wasn't conclusive, but I saw a lot of motion blur in the special moves and such (punches) in the PS3 version that I didn't see in the 360 version. This may be because of the captured footage, but it caught my attention.

    I have a video from the 360 version on my site of most of the contextual attacks. Its missing the tandem ones, but heres a link:

    http://www.the-horror.com/index.php?id=re5vid

    Scroll down a bit to "Biohazard 5 - Contextual Attacks HD.mp4"

    Why are you comparing with those shots, when the PS3 one has obviously been taken from an FLV (and a poor one at that). I mean, look at the huge macroblocks. Nothing can be gained from looking at those two shots.

    A little tidbit I noticed; in the RE5 Gametrailers comparison video, there is a scene where a guy in a helicopter shoots an RPG at a crowd of "zombies", and in that scene, on the 360 version you can see the rotor blades of the helicopter project a shadow onto the guy with the RPG, but said shadow is absent on the PS3 version.

    The picture is more than adequate for comparing the AA, and the 360 version looks to have much better anti-aliasing. I can't say I'm a big fan of this temporal AA business. :???:

    As we already have evidence of what the 360 version is doing, what remains is examining the PS3 edition, not making these "what is better" comparisons.
