Has Sony Finally Fixed PS4’s Anisotropic Filtering Issues?

The lack of AF in certain PS4 games is disappointing but the trend seems to be ending.

Posted By | On 30th, Apr. 2015 Under Article, Graphics Analysis | Follow This Author @GamingBoltTweet


Much has been said about PS4 games lacking texturing filtering but before we delve into that, what exactly is filtering and how does this affect video game graphics? To put it simply, texture filtering minimizes blurring and shimmering of in game textures. As you are already aware, all games have textures which are flat surfaces but the issue is that if the developer does not opt to apply any sort of filtering to it, objects that are near to the camera may look good but those that are away look blurred out. In short, texture filtering is a technical equivalent of anti-aliasing, the only difference being that the former focuses on filling the entire surface of the texture with detail and the latter deals with sharpening out the edges.

In the past, developers have implemented bilinear and trilinear filtering to help look textures smooth. In terms of performance, bilinear is the most basic filtering technology available that allows developers to blend neighbouring textures into each other. This allows textures to have less pixelation but due to its blending process the developer may end up with a pixel coordinate that lies outside the texels. There are ways to tackle this of course but instead of finding workarounds, Trilinear filtering is the second best alternative that developers can use. Although, Trilinear filtering uses the same concept as Bilinear, it also performs linear interpolation to mipmaps. For those who are unaware, mipmaps are essentially a collection of optimized and sequentialized set of textures. However, this type of filtering might result into loss in detail when the player is at an angle with respect to the texture.

This is where anisotropic filtering comes into the picture. Anisotropic filtering combines the best mechanisms from Bilinear and Trilinear filtering solutions but also maintains image quality when the player is at a steep angle with respect to the texture position. This solution further improves image quality by reducing blur when the textures are seen from a distance, whilst maintaining the details at different viewing angles.

With the basic explanations out of the way, let us focus on the subject at hand. Anisotropic filtering has seen some inconsistent implementation on games that are shipped on the PlayStation 4. Let us take a few test cases to see how the implementation of AF widely varies in different games on the PS4.

Evolve:

As is clearly evident from the images above, the PS4 employs a somewhat inferior AF implementation compared to the Xbox One. The textures on the ground have more detail in the distance on the Xbox One compared to the PS4 version.

PS4

Dying Light:

Dying Light’s case is a bit different compared to Evolve. The launch build did had instances of AF at some places and this was merely made more consistent across the game in a patch which was released post launch.

Before patch.

After patch.

DmC Devil May Cry Definitive Edition:

Just like Dying Light, DmC on the PS4 had an inferior AF implementation but this was fixed later via a patch.

Xbox One

PS4

The Order: 1886

The AF in The Order: 1886 was a sign of good things to come. It was the first PS4 game to employ a rather high quality AF filtering across the board. Some inconsistencies were present but they were nowhere close to the titles we mentioned above.

Bloodborne:

Although Bloodborne was somewhat a mix bag, technically speaking, it employed an excellent AF throughout the game. As you can see from the screens below, texture detail and quality is maintained far off within the distance. The game lacked any kind of AA technology but fortunately this did not affected texture filtering.

Dark Souls 2: Scholar of the First Sin

This is our final title that we will take a look in this list. Although a remaster, Dark Souls 2: Scholar of the First Sin featured identical texture filtering on the PS4 and Xbox One. Employing a resource intensive 16 X AF, Dark Souls 2 features extremely detailed textures resulting into no loss of data even when viewed from steep angles.

As we have seen from the screenshots above, it seems that the lack of AF in certain PS4 games is due to game developers facing some difficulty implementing it. Cort Stratton, who is one of the developers behind the console’s GPU API has confirmed in the past that the SDK has no issues in implementing AF on games running on PS4. May be the methodology to implement it was complex. However it seems that it has been fixed if this tweet by Stratton is any indication.

As usual, we will keep a close eye on upcoming first and third party games on the PS4. Hopefully day one high quality texture filtering becomes a trend on PS4 games and not something which is a part of post launch patches.

    Yes but they can’t get rid of it easily because high level AF which is usualy used on XO games requires realy big amount of bandwith and on PS4 the devs using the limited bandwith to be able to reach at 1080p.The PS4 max.reaches 135gb/s so if they add high level AF that means they will cut something else in the game.

    • Guest

      “The PS4 max.reaches 135gb/s”
      Link please, otherwise its just fanboy FUD. And it better be a link to hard facts not some more dumb assuming.

    • Cenk Algu
    • viruzz

      Same with X1, thats just how it works…

    • Cenk Algu

      LoL!!! Please move away because you are flat out wrong;)

    • Guest

      LoL!!! What an idiot. Don’t like the truth eh?

    • Guest

      Ok, so you obviously don’t understand. What part of I don’t want some dumb assuming don’t you understand? Cuz that’s all that is going on there. No hard facts, just assumptions. And where are you getting this 135GB number? Keep making things up. It makes you look smart. We can already see how good your comprehension skills are.

  • Starman

    Not likely ..the system was structured a certain way , so what they’re trying will only be a bandaid ..in the end still not the results you’re looking for , In other words (at the sake of sounding redundant) It won’t work ..smoke and mirrors update ..lol

      You sound like you have vast expertise here given the amount of evidence you bring to the table to support your claims. 🙂

    • Starman

      ????? Here we go …another one … brainwashed and blinded with smoke and mirrors…

    • Cypher-Unknown

      Why don’t you try and enlighten him then?

    • Cenk Algu

      Just read my comment below and you will be enlightened.

    • Cypher-Unknown

      I read it. So, Dying Light, for example, had AF applied and still runs at 1080p. As I understand it, the patch provided numerous improvements yet you say something had to be cut.
      Either what you say is incorrect or any such cuts are so small as to be irrelevant (which, therefore, is not a bad thing).

    • Cenk Algu

      What I say is not incorrect.Everything depends on the bandwith you have LOD,Resolution,AA,AF especially AF and the PS4 is very easy peasy to develop for with it’s dedicated API.If you have arranged everything and something is missing that means you have already maxed out the system.If you put something lately which was not there before,means you must cut something to put it there.

      This is not about being fan or something.It is the hardware.The XO has much larger bandwith rate than PS4.The PS4 max.reaches at 135gb/s while XO can 205gb/s through usage of two different memory types.

      1080p issue generating from the size and very bad API of eSRAM.That is it.

    • Cypher-Unknown

      “This is not about being fan or something.”
      Your post history says otherwise! Your allegiance is pretty obvious so won’t take this any further 🙂

    • Cenk Algu

      Not hding that I am a fan.Yes I am but I know something as wellNot a clueless idiot n ignorant.Bye

    • extermin8or2

      you’re maths is dodgy, the two different memory types do not equal 205gb/s that’s just not how it works…. only certain stuff can b put through the esram and it’s got a tiny capacity so it’s speed isn’t all that’s relevant. I mean 135gb/s x 5GB vs the two different speeds x capacities and time will mean the ps4 can transfer more data faster over a given time period. So you’re wrong, especiall as the fast esram can only be used for a select tasks anyway…

    • Cenk Algu

      LoL!!!!For sure.

    • extermin8or2

      Yes from sure…. I’m a physics undergraduate if there are only a couple of thing s I cant do it’s maths and at least a rudimentary understanding of technology

    • Guest

      Hate to break to you fanboy, but the PS4 had nothing and I mean NOTHING taken away from it. It added, repeat ADDED the AF fix, improved the LOD and added extra lighting. Meanwhile the X1 ver. has received no improvements. Still tears like crazy, has a worst LOD and a worst framerate and lower res. Fact! Sleep tight.

      Oh and PS4 having 135GB/s (oh so now its 135 is it? So is this the new made up fanboy number now) and the X1 having 205GB is laughable. Not only is your PS4 numbers way to low. But your X1 number is to high. The X1’s eSRAM can only do a 109GB/s read or write. In order to do 204GB/s (not the 205, which you obviously pulled out of your a$s, showing that you know nothing). Is only possible if its doing simultaneous read and writes. Something that doesn’t happen often. And even then, that 204 number is only theoretical and MS themselves has already admitted is much closer to 133 to 150GB/s. But also is not sustainable and only wkrs in 7 out of 8 cycles.

    • Cenk Algu

      “The same discussion with ESRAM as well – the 204GB/s number that was presented at Hot Chips is taking known limitations of the logic around the ESRAM into account. You can’t sustain writes for absolutely every single cycle. The writes is known to insert a bubble [a dead cycle] occasionally… One out of every eight cycles is a bubble, so that’s how you get the combined 204GB/s as the raw peak that we can really achieve over the ESRAM. And then if you say what can you achieve out of an application – we’ve measured about 140-150GB/s for ESRAM. That’s real code running. That’s not some diagnostic or some simulation case or something like that. That is real code that is running at that bandwidth. You can add that to the external memory and say that that probably achieves in similar conditions 50-55GB/s and add those two together you’re getting in the order of 200GB/s across the main memory and internally.”

      There was absolutely nothing cut whatsoever. And Cenk Algu or whatever his name is, is nothing more than a Sony hating MS nut loving fanboy. The game had the AF fixed, along with making the LOD better and adding some extra lighting effects that were in the PC ver. without so much as losing a single frame. Meanwhile, the X1 ver. still tears like crazy while also having a worst framerate and all at a lower res.

    • Cenk Algu

      Ohhh yeahhh if I need to be honest yes I don’t like Soy but on the other hand I am not an idiot and blind.I know what hardware is and yes if you add something which was not there before it means you have to cut something.By the ay most games looking better on XO but your loveley DF….no more words!

    • viruzz

      Not a single game looks better on X1, enjoy 900P.

    • Cenk Algu

      Yeahhh boy but in your dreams,not in real World:)

    • Guest

      Wow, you are really beyond delusional and pathetic. You actually believe your own bullsh’t. It must seriously hurt you that the PS4 is seriously beating the X1’s a$s in every way possible. The PS4 has the better graphics in 99.999% of the games and everybody knows it except for you dumb immature fanboys. Bye, grow up. And its obvious you don’t like Sony, you’re on here all the time trying to hard to put down Sony and defend MS. Get over it kid.

      Starman is one of the biggest fanboys on here. Don’t listen to what he says. He says lies and doesn’t know what he’s talking bout. He goes on every PS article to bash the system anyway possible. He’s a true fanboy.

    Herp derp another Gamingbone negative PS4 article, no surprise there at least.

    If “failure” of Anisotropic Filtering (whatever that is) is “disappointing”, it must be earth shatteringly disappointing for YOU when an ancient technology Unreal 3 engine game released in April 2015 still can’t even achieve 1080p on Xbone. Please do an article on that now, of course following it up when Batman Arkham Knight, another Unreal 3 engine game, more than likely won’t do it either.

    And of course people don’t look at it as a big deal, yeah it isn’t, if Microsoft are releasing a brand new Xbox in 2016 to replace Xbone that is. If not, how are ACTUAL next gen engine games going to perform on the console. We can’t really answer that as we haven’t any yet.

    • Starman

      BOOOOOOOOOH !!!!

    • GamingBolt

      It’s not a negative article. You should read the entire thing first. The author is essentially saying that things have improved from the last few games.

    • andy

      Most websites today have done a nice article on the 22.2 Million PS4s sold through to customers milestone. Nothing to say on the matter at all???
      I never saw a SINGLE peep from you ever about the atrocious sharpening filter on low resolution Xbone games at launch or when it was fixed 5 months later either. And if you did it wasn’t as finger pointing as the title and sub title of this article.
      But you always seem to desperately bring up ANYTHING negative towards PS4 at all, even when it is a hilarious one line quote from a small dev, it still shapes the entire article’s title. Your articles from the last week ALONE show this insecure bias on the website.
      Why can’t you take a leaf out of Dualshockers book???

    • Cenk Algu

      Jesus what kind of fanboy are you? I am a fan as well but you LoL!!!

      Actually they did, they did tons of stuff focusing on crushed blacks on the upscaler but of course fanboys are fanboys

    • Guest

      But, you’re a fanboy. So why are you calling him a fanboy?

    • Psionicinversion

      cus he is a fanboy

      Hm, true, you can both be fanboys.

    • TheAdjustmentBureau

      Improvement is what we all strive for. PS is giving us what they promised and they keep improving. I’m happy with this article. Keep up the good work.

    • Don’t stoop down to their level. This is what gaming has become. No longer caring about the gameplay, and dwelling on the graphics. That’s all they care about anymore.

    • Guest

      And whats wrong with appreciating the graphics and wanting all the bells and whistles?

    • Appreciating or obsessing?

    • Gaikai

      It’s gambingbolt what do you expect?

    • You Are Flat Out Wrong

      Booty blasted console peasants crying about their pathetic console not being able to do a basic feature after its pointed out

      But then this is a console that struggles at 30FPS and the fanboys blame the other console because POS4 is so pathetic, they can’t even defend it.

    • Gaikai

      Another pc master troll trying to troll a console article just to get a little attention since nobody cares about pc, can’t find any pc article to read about windows 10 or something? guess not must be tough to play on a platform forgotten by developers and ignored by media can’t help just feel sorry for you poor soul

    • You Are Flat Out Wrong

      You seem upset your console can’t do a basic feature PC does without effort and someone started talking about it

      How garbage is the PS4 that you can’t even defend it and instead deflect to the xbone. Console peasants truly are pathetic

      Go on andy. Defend the PS4’s performance in this screenshot without saying “Xbone” once :^)

    • PcRules

      Well said mate, those stoopid console peasants are so retarded that it’s not even funny LOL!

      Btw, I have an ps4 myself and anyone that have played on a pc knows that it’s pathetic weak!

      Yes I know that it’s garbage performance wise, I just bougt it for some Sony exclusives. Heck as soon as they begin spoken about what kind of hardware the so called nextgen consoles would have I know we are in for a big letdown.

      I mean this is the longest between hardware ps3 to ps4, and all it was also the least difference power wise and thats why it’s even more pathetic.

      But hey Sony/MS just wanted to get some cheap crap out the door and start earning money from day one!

      Annyhow Pc is bigger and better then ever!
      Just let those F*CKN consoles die once and for all!

    • You Are Flat Out Wrong

      “B-B-B-BUH XBONE”

      How pathetic is it that you can’t even defend the PS4 and blame the competition for its failures.

      I’d hate to see you try defend it against a real gaming system like a gaming PC

    • Guest

      What a bunch of deceitful little phonies you Xbox fanatics are. The PS4 version has more grass, period! Deal with it. Its a fact. No amount of denying it will change that. So stop trying to deceive people with your lies and your pathetic MS defense force agenda. Grow up kid.

      MS fanboys are unbelievable, you people are under so much denial.

    • You Are Flat Out Wrong

      Once again, “B-B-B-BUH XBONE U R AN XBONER” and utterly no defense of the PS4 Vs the PC version like I asked

      Thank you for proving my point that PC is the superior platform. As it is, as it should be, as it forever will be

    • Guest

      Who’s arguing that the PS4 is better than the PC? are you alright? Are you hearing voices telling you this in your head? Cuz you are obviously not responding to the conversation here. Take your meds kid.

      B-B-B-BUH PC

    • Manoj Varughese

      I tried all of them on PC but for bloodborne and The Order. So no complaints at all.

    • Guest

      Yeah, PS Poor people tears are extremely delicious aren’t they.

  • Psionicinversion

    More Sony lies… Look this blue pen is red… Sony fanboy ooo what a nice red pen you have!!

    • You Are Flat Out Wrong

      Some day they might see past that 24th frame. But not this generation.

  • You Are Flat Out Wrong

    Noooooooooooope and it never will be fixed.

    LOL Underpowered consoles can’t do something that is practically free without performance hit on PC

    That’s 2x AF by the way. Rather pathetic considering a similar hardware set up on PC gets 16xAF no problem and without any framerate hit. The solution seems to be only a tiny bit of AF. Hilarious and pathetic. Just like PS4 fanboys.

  • RealityCheck2015

    NO Game(on other Home Consoles) can beat ‘The Order: 1886’ in how AMAZING it looks 😛 + All the other games above look LAST-GEN LoL:D (well apart from Bloodborne)

    • Cenk Algu

      Please check out Ryse.It is killing TO1886:)

    • Guest

      TO kills Ryse, much better graphics. And Ryse drops to the teens.

  • From what I’ve heard, from every ps4 fan boy, I thought they were superior and didn’t have any issues??

    • Guest

      It is superior to the X1 and is just having a API software issue. But somehow I don’t think you care about the truth and are just here to hate.

    • Somehow you only think its an API issue. Which you probably have no idea what that means but ill dumb down to your level for a couple seconds.

  • andy

    Here is a great dev quote to do an entire negative article on since that is your thing https://twitter.com/Skullgirls/status/593524998569992192
    Oh wait, this is negative to Xbone, bring it back, abort abort 😀

    • You Are Flat Out Wrong

      Poor poor andy screaming and playing victim complex after being destroyed by superior PC Gamers. No answers at all and trying to change the subject.

      Why is your garbage console not able to do AF?

    • Guest

      Who’s talking about the PC? Are you alright?

  • Wiines 007

    I just played the order 1886 and though the graphics were quit impressive, when I moved my camera from left to right it was a blurr fest. Gta 5 also is extremely blurry. All those pics above look exactly the same. He uses words like “clearly” to explain the huge difference about some dirt on the ground, lol, what a joke. This guy clearly loves monopolizing Microsoft.

  • Triton

    They are just learning to work around all the issues.

  • Fayxz

    Its a bandwidth limitation, 135gb/s is not enough and the cpu is slowing down the gpu. Xo can actually achieve 205gb/s at raw peak but esram api is so bad that games are hitting 900p. Both systems have flaws but it looks like xo will eventually catch up and possibly have both same res but better af
