PS4 game Killzone: Shadow Fall dev responds to 1080p controversy

Guerrilla Games confirms that PlayStation 4 game runs natively in 1080p and uses technique called "temporal reprojection"; dev promises to be more precise about resolution in the future.

Killzone: Shadow Fall developer Guerrilla Games has responded to debate over the game's native resolution and frame-rate, confirming in a blog post today that the game does in fact run natively in 1080p at 60fps for both single- and multiplayer.

The blog post comes, ostensibly, in reaction to a Eurogamer report that found that the Killzone: Shadow Fall multiplayer mode opted for a 960x1080 framebuffer as a means to achieve 60fps. Some fans were miffed by this report, saying Guerrilla Games and Sony hoodwinked them.

Guerrilla Games explained today that it uses a technique called "temporal reprojection" to combine pixels and motion vectors from multiple lower-resolution frames as a means to reconstruct a full 1080p image.

"If native means that every part of the pipeline is 1080p then this technique is not native," producer Poria Torkan said. "Games often employ different resolutions in different parts of their rendering pipeline. Most games render particles and ambient occlusion at a lower resolution, while some games even do all lighting at a lower resolution. This is generally still called native 1080p. The technique used in Killzone: Shadow Fall goes further and reconstructs half of the pixels from past frames."

Torkan said Guerrilla Games is aware of the community's "degree of investment" on this matter and that the conventional terminology may be "too vague" to effectively explain what's actually happening under the hood. He said Guerrilla Games will "do our best" to be more precise with its use of language in the future when addressing its development techniques.

If you're interested in the technical minutiae of the technology and techniques behind Killzone: Shadow Fall, be sure to read Torkan's full blog post. Guerrilla Games will also discuss the game's rendering techniques--including temporal reprojection--during the Game Developers Conference later this month. GameSpot will be in attendance at the show.

This resolution stuff is the new-gen version of the bit wars, where initially it's a big deal but technology eventually has gotten to the point where it really doesn't matter. As long as the final image is output at 1080p, and the actual rendering is done at a resolution close to native (ie 1080p for an HDTV), then I'm sure most people will have a hard time telling the difference even when comparing them side by side.

Ryse&Killzone still look great, so who really needs 1080p? And it's not like the games won't look more amazing anyways in a few years(GTA5 says hello)

Soooo are we giving just giving Sony a pass here? All these months the Xbox One got flack for it's resolution issues and has been widely referred to as "The Xbone720P", and here Killzone is not really true 1080p and 60fps itself. That was part of it's whole selling point! The game DOES look fantastic, but lies are still lies you know. In comparison, Forza 5 actually IS 1080p 60fps and that's an admirable feat not to be downplayed. So do we start calling Sony's new machine the PS1080i just because of this? MS hate is very popular nowadays and in alot of ways warranted, but Sony's new console and its games cannot escape the same criticism if we're all about fairness here.

If a game looks good it looks good. Who cares if it's not officially the resolution you want. I just hope this isn't a fanboy issue(but it probably is due to entitlement issues, smh). I'm glad I only care about whether a game is actually good or not and ignore the resolutions. I will always take a game with good gameplay over a pretty, but shallow game. Reminds me of those who say Dark Souls I and II don't have good enough graphics, really?

LOL another lie the single player plays at 30 FPS not 60 already confirmed by many frame rate tests but at the end of the day it's nothing to do with res or frame rate it's to do with the lying to peoples faces, Sony has a habit of this long before the PS3 was even released, this is nothing new, at least MS were straight up front with their bs I think it's about time Sony did the same.

WHO CARES! So many people get wrapped up in the numbers game. Half of them don't have any idea about what it is that they're arguing about and how insignificant "native" really is to the overall picture quality. Devs are always using different techniques to accomplish their vision. If when you turn your tv on, startup the game and the tv displays 1080p up in the corner... You're golden. That's really all that matters.

At this point in time, especially with next gen systems, devs are gonna make their games look as good as they possibly can. That's a given. So it's unnecessary to put additional pressure on a dev about "native" 1080p when sitting on a couch 6+ feet away from the tv and you wouldn't be able to tell the difference between native or not. And I don't want devs focusing on 1080p and then the rest of the game runs like shit because the media and ignorant gamers have put such an emphasis that native 1080p is some sort of qualification to a good game.

This was such a stupid thing for the media to focus on. I wonder who started it (probably Eddie Magoo). Because I'm really getting tired of seeing an article for EVERY game that comes out and whether or not it runs natively in 1080p. Address more important things that gamers actually give a shit about

In other words, it's basically a form of 1080i.

For those who can't tell the difference, move along. Nothing to see here.

For those who can tell the difference but don't care, move along. Nothing interesting to see here.

For those who can tell the difference and get annoyed by non-native resolutions, move along. PC's are over that way.

Fan boys are the only people that would care about this crap. The average user will not and probably will never be able to tell the difference, and at the end of the day that's all that matters.

Is this a joke? The people who complained are obviously the ones who can't tell the difference in resolution by looking at the game so their complaint is instantly invalid. NEXT!

tomtomtom1230

Why does it matter? If they told me it ran in 200p at 2 frames per second, or at 4k at 120hz, it makes no difference. It's a good looking game.

I don't know what is all the argument, the game runs in 1080p. The single player is still direct native while multiplayer uses an advance rendering technique for better result that in the end is still 1080p. Just go and read the "blog" link and it explains very clearly what it is. Here, I will paste what is said from the blog.


Xbox One - "Up-scaling is a spatial interpolation filter. When up-scaling an image from one resolution to another, new pixels are added by stretching the image in X/Y dimension. The values of the new pixels are picked to lie in between the current values of the pixels. This gives a bigger, but slightly blurrier picture."

Playstation 4 - " Temporal reprojection is a technique that tracks the position of pixels over time and predicts where they will be in future. These “history pixels” are combined with freshly rendered pixels to form a higher-resolution new frame. This is what KILLZONE SHADOW FALL uses in multiplayer"

Clearly PS4 is still the more superior machine and again this technique was only used in Multiplayer in Shadow Fall to improve the smoothness of the gameplay while still retaining the quality of a 1080p rendered frame.

What is sad here is that "Temporal Reprojection" as mentioned by some of the people below, is a technique that is created by Microsoft and their Xbox One is such a weak machine that it CAN'T even use their own technique to render their game for better result.

The butthurt from Xbone fangirls is glorious!!!

Thanks for the clarification, Guerilla! Me and 2.1 million gamers also appreciate free dlc for mp.

The few people dumb enough to have bought a Xbone wish they had it. Cry harder, women.

@jayjay444 Sounds like a communication error. Anyone who followed killzone knew it ran at 60 FPS in multiplayer and 30 in singleplayer so they could really push the graphics. This wasn't any secret.

@psmithiv  you don't play much then. Homefront, 007 Legends, Gears of War: Judgment, Duke Nukem Forever... and that's just few recent ones.

@bj91x  Yeah, about that. In that matter even on PC only PEZ like 2D indies are native 1080p.

@Joe51187 what did they complain about, the look or the way it was/is being handled, if they are complaining about "the look" then you are right, if they are complaining that "to have information carelessly handled like this isnt on" then you are wrong

ModifiedSoul

@tomtomtom1230 exactly as long as thats how they marketed it for what it is then no problem, the funny thing is i think if they had of been upfront with this and labelled it something like 1080tr and just said we are doing this to maximise frame rates for the gamers i dont think anyone would have a problem

rickphoenixxx

@nobody490 More superior? If MS was caught using cheap tricks on Forza 5 to get it to 1080 then there would be a shitstorm of hate. LYING about a game being 1080p 60fps is a serious offense and shows that the PS4 has no real advantage over the X1 even with it's fancy super duper gpu. Upscaling/temp projection whatever trick employed its still a trick. This is "The power of the cell and emotion engine" alll over again.

Gen007
Gen007

@nobody490 no that does not count as 1080p native no way in hell when its up-scaling. If that counts then x1 games are native 1080p as well because the temporal projection is up scaling and interlaced at that. Granted its a more advanced upscale technique then whats normally used its still upscaling. 1080p native means the game puts out 1080p untouched in anyway. Internally this game is using lower resolutions to make up the final one and that's exactly what we aren't looking for when we say native.

ModifiedSoul
ModifiedSoul

@nobody490 i read it and considering that each frame is only 960x1080 and uses the previous frames to make up the missing gaps then that is not 1080p it is an advanced interlacing technique which is still sub 1080p. they are going the wrong way about dealing with this. "we are sorry for the confusion but here is what we did (insert tech talk)" and leave it at that and stop calling it 1080p because the only way it would be is to redefine what 1080p means

@eternal_napalm Have fun with your generic Halo sub-1080p knockoff. You should try that new Titanf....oh wait nevermind. I heard Knack is fun so there is that.

@ModifiedSoul There is a guy in that blog that posted a comment I thought said it best of what is about.

"... The Multiplayer is always making a 1080p image that is unscaled every frame. That's the standard definition of 1080p. If you say that's not 1080p, then almost no game, even computer games in some cases are not possibly 1080p. People say, my emulator etc plays games at 1080p and this is technically right. Killzone isn't stretching the image, it's compensating unnecessary usage of power by referencing 2 previous frames and the closest one is full 1080p as well. In the end they are creating a brand new image per screen with no stretching, just image prediction pretty much..."

@lonesamurai1 @Frosty192  i have a gaming rig with a 3770k and 2 780 classifieds and i was really impressed with the visuals in killzone, probably one of the best looking games i have  seen pc or console. And im not a sony fanboy i have both new consoles.

@nobody490 @ModifiedSoul that still is not 1080p that is an advanced form of 1080i the end image is 1080p the same way an upscaled image is 1080p at the end here as far as only resolution goes

1080p>1080tr*>1080i

still not 1080p

@nobody490 @ModifiedSoulHe made almost the same comment further down It will be interesting to see how he tries to get around the facts. Whoever posted that comment is doing a good job at putting it in a way even xbots can understand, they won't understand, but at least he dumbed it down enough to where they could if they chose to.

@blkgsr @lonesamurai1@Frosty192It isn't that impressive especially when compared to Crysis 3 on any platform but of course the PC version will take it by the scruff of it's neck.
 

It amazes me how you own a nice PC and you're are still impressed with graphics on a game like that, on a machine like that I own both consoles and nothing I've seen on them impresses me from a graphics standpoint, really strange for you to be impressed.

Nah, I just called you out for being a liar and a hypocrite. Don't call someone out for something you can't defend. And by using u stupid to slight someone's intelligence is rather funny. The only feelings I caught from you are are feelings of sadness. I feel sad for simpletons like you. You can even confront your own hypocritical ways. You're just a trifling Sony hoe.

And on the subject of haters, how could you give Forza 5 a review score of 1 in August when the game didn't come out until November? You want to talk about hate you lie to the skin of your teeth just to hate on something you have no interest in. I can see if you played it and gave veiled reasons for why you didn't like it but come on now, your fanboy is showing. I bet you have a Playstation tattoo. It's fanboys like you that make me not want a PS4 because then I would have to deal with babies like you online.

So a person with the name Tiger Ali is cracking on another person? And you're gonna Crack on a picture with that profile pic of you next to a tractor trailer truck? Who the hell is that happy to be at a rest stop? I can't hate though. You look very happy. You look like you won a bronze medal at the Special Olympics.
