Sony Explains How Checkerboard Rendering Works On The PS4 Pro

Great yield with fewer resources.

The PS4 Pro is definitely not powerful enough to support native 4K rendering for most games- instead, Sony uses a custom upscaling solution which is referred to as Checkerboarding. Checkerboarding can be a demanding technique, but if utilized right, with access to the triangle and object data in the ID buffer, the results can be visually resplendent.

“First, we can do the same ID-based colour propagation that we did for geometry rendering, so we can get some excellent spatial anti-aliasing before we even get into temporal, even without paying attention to the previous frame, we can create images of a higher quality than if our 4m color samples were arranged in a rectangular grid… In other words, image quality is immediately better than 1530p,” Mark Cerny explained to Eurogamer’s Digital Foundry.

“Second, we can use the colours and the IDs from the previous frame, which is to say that we can do some pretty darn good temporal anti-aliasing. Clearly if the camera isn’t moving we can insert the previous frame’s colours and essentially get perfect 4K imagery. But even if the camera is moving or parts of the scene are moving, we can use the IDs – both object ID and triangle ID to hunt for an appropriate part of the previous frame and use that. So the IDs give us some certainty about how to use the previous frame. ”

So far, so good. But what are the benefits of checkerboarding versus traditional geometry based rendering?

“[With] checkerboard rendering, the first two pluses are the same: crisp edges, detailed foliage, storm fences, but also, increased detail in textures, increased detail in specular effects,” Cerny said “But we’re doubling pixel shader workload, there are other overheads as well and it may not be possible to from 1080p native all the way up to 2160p checkerboard.”

The end result, however, is great looking games with relatively fewer resources and effort required.

“The point though is that these are techniques that can be implemented for a fraction of a per cent for the overall budget for the title,” Cerny said.

The PS4 Pro is due out next month, on November 10. It will be the first 4K capable console on the market (the Xbox One S technically supports 4K video, but for games, only goes as high as 1080p).

Awesome Stuff that you might be interested in

  • DA-ROOSTER

    The PS4 PRO is the first fake 4K console on the market

    • Riggybro

      The second one will be released late next year.

    • Mr Xrat

      And it’ll have a year to itself before the second fake 4K and first with no exclusives on the market comes out, Kirk.

    • Chris

      Having plenty of experience with 4K for the past two years I can say for sure that a GTX 970 is capable of rendering medium graphic quality(AA off – total waste at 4K) and still achieve 45-60 FPS. The PS4 Pro is .3 tflops higher in performance alone which is 7.5%. Throw in more advanced rendering techniques and clearly 1800p is doable. From there upscaling will normalize resolution and I personally prefer the 50-75% advantage we will see.

    • TheNorthFace

      cpu and ram is weak in pspro so don’t expect anything but the same graphics at 1800p 30fps

    • Chris

      Ram speed on PS4 Pro is 218gb/sec vs 224 on the GTX 970 & 980. I will agree the CPU is weaker than the average Intel 4 core but utilizing DX12, Mantle, Vulkin ect CPU loads are massively reduced.

      Do a search for PS4 Pro screenshots…definitely a big step up from the blurry 2013 console graphics we are all used to and an extra gigabyte of ram, 4K streaming, +500gb and HDR(biggest improvement for me with Sammy 55KS8000) for $100? Hard to beat for sure. Normally I PC game but starting now a console is also an option for me.

    • V8Supercar1

      Considering the fact that the ps4 pro will have some native 4k games on it. (NBA 2k17 was already confirmed to be native 4k/60fps) The ps4 is definitely not a “fake 4k console”.

    • Storme Prince

      Doing 4k on games with low graphics is not that impressive.

    • ProAssassin84

      There is Native 4K games on PS4 Pro. Quit looking stupid.

    • Mr Xrat

      Kirk looks stupid everywhere he goes.

  • Nintengods

    *4kPR
    **No 60FPS either

    • Gary

      actually I think Cerny did say developers can take advantage of the new power of the pro whatever way they want, whether it’s resolution over quality or quality over resolution.

    • Nintengods

      And you will get neither on the P$4 Prolapse

    • ProAssassin84

      Enjoy your Switch Fisher price Tablet.

    • Agent HUNK

      have fun with the switch when that fizzles out in 6months with no games to play

    • Samus

      You sound… salty. lol

  • Mr Xrat

    Interesting technical stuff. If only MS had engineers smart enough to do this; they’ve only just figured out how to get rid of the power brick.

    • crazy_black_man-

      LOL!!! They still aint figured out how to put the glowing red ring back on the front of the console so they can get these suckers to go out and buy more Xboxs. Hilariousness!

    • Exare

      They still haven’t figured out how to make an intuitive UI or make it run smoothly either.

    • EmpeRawD

      And judging from this article it would seem that you Sony die hards have yet to figure out that “Checkerboard Rendering” is just a fancy word for upscaling. And we all know how much sony fans hate upscaling!

    • J.j. Barrington

      Everybody but you knows what’s going on here.

    • ProAssassin84

      Yes because we will listen to you working at McDonalds serving happy meals then Mark Cerny who engineered the best selling console since PS2. STFU.

    • EmpeRawD

      doggystyle is that you? Are you still spreading the gospel of Hirai every chance you get. Where are the rest of your Sony Defense Force clowns?

    • Mr Xrat

      The glowing red rings they have now are the ones located between their rosy red cheeks.

    • TheNorthFace

      so now you like upscaled gaming, but disliked it when xbox one did it? http://www.extremetech.com/wp-content/uploads/2013/11/southpark-mmo-gamer-ps4-gamer.jpg

    • Hvd

      you cant talk to them its like talking to a sack of rocks…lol

    • Mr Xrat

      Amusing considering you’re as dumb as said sack.

    • Hvd

      nothing intelligent starting down the insult path which is what usually happens when you got you as* handed to you.all you can do is insult now its pretty pathetic.

      al im going to say is have fun wating for your dealyed games until next year some time.

      only on the delay station where delays await….lmao

      im done with you….lol

    • Mr Xrat

      MS could have easily put out a full 1080p console in 2013 for $399.

      They could not easily put out a full 4K console in 2016 for $399.

      Figure out why the Xbone was a laughing stock, little Faisal.

    • Note5

      Yup…Lots of money but less brains

    • ProAssassin84

      Microsoft been playing catch up since 2005

    • babadivad

      Didn’t Quantum Break use checkerboard rendering? I’m sure they did.

    • Mr Xrat

      It sure did – a different checkerboard rendering technique. The Pro’s doesn’t make games look like a smudged mess. Still, Remedy did the best they could with the **** they were given.

  • The PS4 Pro is “definitely” powerful enough to support native 4K rendering for the following games:

    – The Last Of Us Remastered (Native 4K@30FPS)
    – Smite (Native 4K@60FPS)
    – The Elder Scroll Online (Native 4K@30FPS)
    – The Elder Scrolls V: Skyrim Special Edition Edition (Native 4K@30FPS)
    – Mantis Burn Racing (Native 4K@60FPS)
    – Wheels of Aurelia (Native 4K@60FPS)
    – Futuridium EP Deluxe (Native 4K@60FPS)
    – forma.8 (Native 4K@60FPS)
    – Rez Infinite (Native 4K@60FPS)
    – Hustle Kings (Native 4K)
    – Thumper (Native 4K)
    – NBA 2K17 (Native 4K@60FPS + HDR)
    – Bound (Native 4K@60FPS)
    – Viking Squad (Native 4K@60FPS).
    – Pro Evolution Soccer 2017 (Native 4K@60FPS)

    And these are just the ones we know about.

    • TheNorthFace

      cool native 4k with ps3 graphics…..

    • Za Dragoneel

      lol…you high??

    • Mr Xrat

      “I-it can’t do 4K!!”
      “Here’s a list of games that do.”
      “T-they don’t count!!!!!”

      As usual.

      Though you’ve figured out how Gears, Forza and Halo are going to be 4K on the Shitpio next year.

    • Agent HUNK

      ps3 graphics….. ? umm.. what?

    • Demetrius Radford

      All of these games arent that gpu heavy. lol

    • J.j. Barrington

      What’s that gotta do with anything?

    • Storme Prince

      Even a weak console can do 4k if you make it run mario 64 when people say it can’t do 4k they mean it can’t do 4k with a game with graphics that are intensive for current gen.

    • J.j. Barrington

      That’s not at all related to being GPU heavy.

      That aside, how many people are playing in 4K with “graphics that are intensive for current gen?” Not a whole lot. It’s certainly possible that PS4 Pro sales will eclipse the number of PC gamers doing their thing as you describe by year’s end, because there simply aren’t many people doing it.

      I could go on. I could talk about the fact that the games run natively at 1080p or better, or how there are already some non “Mario 64” titles that will be rendering in 4K. I could even damage that excuse by going into how much power would be required to render a game like Mario 64 in 4K. But I don’t think it’d matter.

    • Samus

      I prefer non native. True 4k is a waste of resources on anything but $2000 PC’s. 1800p will be a perfect balance imho. Horizon Zero Dawn, Spiderman etc.

      Edit: And I have a decent 4K TV.

  • Hvd

    wow you guys make it sound like they invented it….lmao

  • EmpeRawD

    I’m confused. You Sony clowns did nothing but make fun of the X1 when it upscaled 720p or 900p to 1080p since the start of this generation. Now that the PS4 Pro is pretty much doing the same…it’s okay now?

    https://uploads.disquscdn.com/images/9e2f1f798ba26237a89bd052a7f2ed74d4131b77741d44deea3d81a8a4b1a873.gif

    • Za Dragoneel

      that face looks scary bro….but PS4 Pro has more GPU power 4.2 TFlops and some extra ram and its different GPU architecture (meaning different/better technique), where Xbone didn’t have that so not really a fair comparison as you will see in future (because it will look better)….

    • EmpeRawD

      And they lived happily ever after right?

    • Mr Xrat

      MS could have easily put out a full 1080p console in 2013 for $399.

      They could not easily put out a full 4K console in 2016 for $399.

      Figure out why the Xbone was a laughing stock, PrinceLittleD.

    • EmpeRawD

      You said that already. You sound like another idiot that used to troll forums like this. He/she/it was very Extreme. You and your five other accounts have yet to answer my questions

    • J.j. Barrington

      I’m confused. You STILL don’t have a console capable of even the power of the vanilla PS4, yet you have the gumption to talk trash?

  • TheNorthFace

    ooo fancy ‘checkerboard’ is merley just PR talk for UPSCALING, the same hate xbox one got for upscaling 720p/900p.

    sony is really playing ‘checkers’ with its dumb fanbase by releasing first, while ms is playing ‘chess’ with its powerful scorpio, reliable online service and feature filled OS, psn was down on cod beta launch, ouch that scorpio does STING.

    • Chris

      Uh, think the real issue with the Xbox One was the performance. Less GPU cores and 32MB of DRAM like a wheel chair to help its crippled DDR3 ram. Playstation has once against delt a blow to the Xbox in the performance arena while Microsoft promises to play catch up “Holidays 2017” which is clearly over a year away. Now lets not forget the GPU in the Pro is simply an RX480 down clocked slowing throughput from 5.8 tflops to 4.2. If Sony took a page from Microsoft and upped the performance of their GPU in an update as Microsoft previously chose to do with their CPU the sting might be more of an itch.

      Sony have kinda been plain speaking about the 4K gaming being up the to developer in regards to going strait 2160p or 1080/1800p route with upscaling but I will take upscaled 1080/1800p all day over 720p.

    • Danny MacGurk

      Plus they may just release Scorpio early because they’re already so far into it. Plus to shut down Sony pros slimy move

    • Mr Xrat

      Aahahahahahaha, yeah, I hope they try. I’d love an $899 debacle with RROD-style design deficiencies.

    • Danny MacGurk

      I hope u get cancer u rat puke

    • Mr Xrat

      You too, Xbox scumbag.

    • Mr Xrat

      It’s not PR talk, it is an upscaling method. It’s far better than whatever upscaling the Xbone tries to do, and I hope for the Shitpio that MS works out an equivalent or better upscaler.

      Amusing you talk about a dumb fanbase when you’re waiting a year for promises and no exclusives, Little Faisal.

  • JuneMas

    The PS4 has plenty of games that are 900p including the recent Mirrors edge and Battlefield 1. Both consoles were under powered, however Sony having the more powerful console with Microsoft falling flat out the gate with a high price tag and mandatory kinect was where they failed. Sony making games in higher resolutions but still only 30fps or higher resolutions with no AA isn’t what gamers wanted. 1080p with high visuals and 60fps from both consoles was what gamers expected. Sony taking this half step isn’t an upgrade worth having. Maybe Scorpio would have been if parity wasn’t needed with the current X1. PS5 abd the Xbox beyond Scorpio is where true 4K will come in.

    This pretty much sums up the entire Hirai worshiping Playstation Nation!!! LMAO

  • neiliewheeliebin

    Native 4K with less detail than 1080p ultra on PC hooray for upscaling
