    According to Guerrilla: http://www.killzone.com/en_GB/blog/news/2014-03-06_regarding-killzone-shadow-fall-and-1080p.html
    You can also see that in the link i posted above in his "rendered pixels" comparison and the final result. Regarding AA, there was a GDC presentation yesterday about this, maybe you can find it :razz:

    The motion blur in Interstellar reminds me of the order. I wonder if we will ever witness a game with such graphical excellence ever again. It was no checkbox tech, like star citizen (which looks ugly as hell / extremely unpleasant), but rather carefully chosen effects which accumulate in the most visual stimulating package to date. RIP Ready at Dawn :-(

    Other games' motionblur are so messy and incorrect I can't even look at them anymore

    Seems pretty good to me (look at the lamp in the background).

    RaD announced they are switching to a PC for a bit, porting Order engine and making some VR project.

    All of that is nice, but what I want is a sequel to Order [with expanded.... well everything]. :)

    Sorry, for the misunderstanding. I meant "RIP the order" of course. Btw I absolutely loved the Order, every second of it. I played about an hour at a time, taking my time marvelling at the environments and listening to the excellent soundscape. The combat and the weapons were super also, especially the thermite rifle and the sound it makes when you spray the thermite. I really enjoyed the story as well.

    The only thing I hated was the media reception. Kotaku or Eurogamer even went as far as creating a " you shouldn't pre-order the Order" article. Something which has never happened before in the history of videogames, even when they knew the actual bethesda or ubisoft game was broken and would be in the months following release.

    I see The Order as a special wine which only few people can truly enjoy. Which is a shame because it is a rare masterpiece. And that includes the motion blur :)

    I want a sequel as well! I really hope the game did well enough for you to warrant a sequel. Unless you guys hated working on it, in that case, I will cherish The Order forever but I hope for you guys I will never be president, because then there will be a The Order 1889 ;-)

    Well thank you for the kind words guys. :)

    Anyhow, to get this back on topic...the actual motion blur algorithm was based on Morgan McGuire's work, with a few last-minute optimizations that were inspired by Jorge's presentation from SIGGRAPH. So there's not really anything particularly novel in our implementation, but we did definitely spend quite some time on both the engineering and design/art side to make sure that the quality was consistent.

    Interesting excerpt found in the Morgan McGuire's work, thanks @MJP :

    So some do recommend being reasonable with motion blur, even in films, because otherwise objects in motion would be too blurry. No kidding.

    Aren't those recommended settings rather low? Do we know some specific settings used in some current games?

    I vehemently disagree. First it's too strong (which is sadly usual for a 30hz game from Naughty dog), and secondly the motion blur itself doesn't keep enough information from the original pixels. It's what I call cheap.

    [​IMG]

    Driveclub (RIP :mad:) has a much, much better motion blur IMO. Compare how the leaves are motion blurred in Driveclub VS how the grass is blurred in UC4. The blur in UC4 is basically that: a cheap blur just for the sake of blurring it, you loose a great deal from the original information.

    [​IMG]

    In Driveclub there is really a motion blur that is simulated. They call it "plausible motion blur" in my previous link. You can easily see the "direction" of the blur, and those directions are consistent with the direction of the camera. In the end it's much more sharp, even in motion. The judder is taken care of, while reasonably keeping some clarity from the original pixels.

    For me the difference of quality between those 2 pics is super obvious. Apples vs peaches. Uncharted uses a cheap motion blur (and too much of it) when Driveclub uses a high quality motion blur with a lighter setting. Remember that I have taken the Driveclub pic a full speed, maybe 200 km/h VS maybe 50 km/h for UC4. But hey It's only a jeep. Even the cars in UC4 are cheap. :lol2:

    I get similar perceptual results when I compare motion blurs from Battlefront VS MGS5, both 60fps games. Battlefront is much better at keeping some information in the image. Even if Battlefront moblur is less good than Driveclub's, it's still better than MGS5 moblur.

    Ok, once again with the movie example. Another good one (Casino Royale this time)

    Look at the foliage in the background in the last shot (on a very slow moving vehicle i might add), as I've said before, it boils down to i prefer X technique more when it comes to strength of the moblur applied and not the actual quality of the application. But i at least hope for your sake ND have a motion blur option in the menu :p

    Lol so your feeble attempt to convince me (not enough moving green leaves in the last pic) was just a poor excuse just for the sake of posting the best looking Bond girl ever? :wink4:

    Not, wait you are right, this Green is indeed the best looking ever! You convinced me!

    But i also made a point, motion blur use varies from game to game and even if we take a look at movies (which is what everyone tries to imitate in recent AAA games) it's hard to tell which technique is "best". Movies tend to blur the image a lot more than games do and it still doesn't look off or blury when watching a film (because of the density of information in focused areas i guess?). In any case, i'm perfectly fine with the current implementation in Uncharted 4, i think it looks great in motion.

    You made a point indeed and your posts are really showing where the problem IMO is in most people's minds. Motion blur and others effects like CA, DOF or grain filter in videogames are often used in order to imitate the look of movies.

    When it should only be used in order to remove the judder while, if possible, retaining some details from the original content. And we know it's possible to decently have both. I think that some developers only use motion blur in order to remove some judder (Driveclub, Battlefront) when others developers use it like a tool in order to have a filmic style (UC4, MGS5).

    And it's indeed totally consistent with the tradition of those developers: Evolution / Dice was / is striving to do realistic games when Naughty Dog and Kojima are striving to do videogames that tend to look like movies, both structurally and with the artstyle.

    Uh...


    How is that not like a movie? I don't think the line in that argument is as clear as you think it is.

    How is that realistic

    And U4 is not? I think we've already clarified that whatever doesn't properly track eye movement (position, depth, focus) isn't realistic by definition.

    The game itself has in fact a realistic artstyle. It's like you really are in the world that is depicted in the movies.

    Battlefront is one of the most realistic game released so far this gen. I think the PSVR version will impress a lot of people. This game was meant to be ported to VR!
