What is Checkerboard Rendering? How it Works on One X and PS4 Pro?
Microsoft'south Xbox One Ten and Sony'due south PlayStation iv Pro are 2 of the newest and most powerful gaming consoles, that promise gaming at 4K resolution. Although the PS4 Pro has been bachelor since last November, you won't be able to get your hands on the much more powerful Xbox 1 10 until this November. Technically, these are still 8 generation gaming consoles, with hardware upgrades under the hood over the existing PS4 and Xbox I, in guild to brand it capable for gaming resolutions beyond 1080p.
Hang on, at that place'due south a catch hither. Sony has already claimed that their newest panel makes use of Checkerboard rendering technique, to push the resolution to 4K. Nevertheless, during the Xbox One Ten launch back at E3, Microsoft were boasting about how their latest panel was capable of Native 4K Gaming. Sure, it's true to some extent, but the console volition not exist able to hit Native 4K on all upcoming games. The console is claimed past analysts at the Digital Foundry to make utilise of the same Checkerboard Rendering technique, to attain the 4K target in certain games like Anthem and Assassinator's Creed: Origins. If you lot accept no clue what we're talking near, allow'south accept a detailed wait at what checkerboard rendering is, and how it works on Xbox One Ten and PS4 Pro:
What is Checkerboard Rendering?
Checkerboard Rendering is a relatively new and unique graphics rendering technique to assistance a organization's GPU, in order to return a game's visuals at college resolutions than what it's really capable of. Just put, Checkerboarding lets a GPU return graphical textures at a resolution, without having to natively render at that resolution, and it'southward used in cases where the GPU just does non brand the cut in terms of horsepower. Although checkerboard rendering can be considered every bit a custom upscaling solution, it'due south not even close to upscaling by whatsoever ways. You'll realize that when nosotros compare both of these techniques in a bit. That beingness said, this is pretty much a demanding technique, but if it's properly utilized, the potential is limitless, specially when the developers accept admission to object and triangle information in the ID buffer.
Devices That Use Checkerboard Rendering
Checkerboard Rendering is currently being implemented on the new gaming consoles, namely the Sony PlayStation 4 Pro and the Xbox One 10. However, the former did permit the whole globe know regarding the fact that their console utilizes Checkerboard Rendering at its full potential, in society to provide a near 4K experience that users volition observe hard to differentiate from.
On the other hand, Microsoft always touted their latest Xbox One X a.1000.a Projection Scorpio every bit a True 4K gaming panel. The visitor even went ahead to say that they don't consider the PS4 Pro as a competitor to the Xbox Ane X, as it's totally in a dissimilar league. That'due south truthful to some extent, as the PS4 Pro natively renders at 1440p on most of the games, and make utilise of this checkerboard rendering technique to push button the resolution to 4K.
Well, nosotros've seen a bunch of games running at Native 4K/sixty fps on the Xbox I 10 during E3 2017. Yet, this is clearly not the case for all the games. Xbox One X packs specialized hardware for checkerboard rendering, just in case the GPU that powers the device is incapable of rendering a particular game at Native 4K resolution. Even before the console managed to hitting the stores, we've already seen games like Anthem and Assassin's Creed: Origins making use of this technique for providing a 4K gaming experience, as anyone with a fair amount of knowledge in this department would immediately realize that the 6 TeraFlop GPU on the Xbox I 10 is but non good enough for Native 4K gaming on all the latest games. A couple of years down the lane, nosotros'll only exist seeing much more games that will utilize checkerboard technique, as the GPU housed in the console ages.
Checkerboard Rendering In Gaming
The Checkerboard rendering technique have started being utilized by game developers always since Sony's PS4 Pro panel came into beingness last year. Then, the technique is relatively new and it'southward primarily aimed towards rendering games at 4K resolutions. A lot of PC games that we've seen over the recent years have shipped with 4K textures, and almost all of them were fully capable of native 4K resolution. However, in order to game at those resolutions, you demand to invest thousands of dollars on a high-end gaming rig. The latest consoles, on the other hand are usually priced at the sub 400-500 dollar mark. In order to reach 4K gaming at this cost point, the manufacturers need to sacrifice on Native 4K gaming, as the GPU housed below the chassis, for this price betoken, is just not proficient plenty to do that. This is exactly why Checkerboard Tendering has been put to skillful use on gaming consoles.
At that place are basically 2 types of Checkerboarding that can be utilized. One of them is the Interpolation based rendering technique, which is quite dated and another one is the newer Temporal Checkerboard rendering technique, which is used by PS4 Pro and Xbox One 10 developers for their games. This technique trims downwards the details where a homo centre isn't clearly focused on. An boilerplate homo middle can only focus on specific areas of the screen, and this, in turn is exploited by the checkerboard rendering technique. Crisper edges, much more detailed foliage, increased details in textures and specular effects can be expected as a result of Checkerboard Rendering, without much workload on the GPU front.
Simply put, you can experience games in a much more enhanced visual fidelity without the need of a top-tier graphics carte du jour for pushing all the frames. However, what y'all might notice includes some sort of artifacts in a crisscross design, especially in fast motion scenes, as depicted in the picture below.
Checkerboard Rendering vs Upscaling
Before you jump to conclusions, nosotros'd like to say that there'southward a stark divergence between Checkerboard Rendering and upscaling. To put this into perspective, upscaing is nothing but taking a video at a particular resolution and scaling things up to a college resolution. We've seen this in almost all the modern TVs. Even the older Total HD TVs had upscaling prowess to calibration everything up from 480p to 1080p, for a slightly enhanced appearance. Consider a frame in a particular footage. In upscaling, this frame is enlarged, so that each original pixel sits above portions of multiple pixels. A compromise method blends them and selects final values. That existence said, how much of an enhancement that yous get, depends primarily on the device that yous're using. However, it'due south nowhere shut to the much more enhanced visual allegiance that you'll feel equally a result of Checkerboard Rendering, as this technique only doesn't scale things up, if that's what y'all're thinking.
Moving on to Checkerboard Rendering technique on the new 4K capable consoles. In order to construct a completed frame, there should be ii sequential checkerboard frames that enters the rendering pipeline. Assume a checkerboard comprised of black and white tiles. Here, consider that one frame, say "North", is every single black tile on the checkerboard and the subsequent frame N+one, is every unmarried white tile. Frame N is a resultant of the prior completed frame, with half the pixel count, and Frame N+1 is a new frame with new onscreen data, but also packs half the pixel content. Then, the Checkerboard rendering technique will make utilize of the ID buffer, which is a specialized hardware housed in the PS4 Pro and Xbox Ane X consoles. It tracks the movement of frame North'southward pixels and compares information technology with the pixels on frame N+i, and project the old pixels to the new location on frame Due north. This projected frame North, volition in turn be merged with frame N+1, in gild to construct a 4K resolution frame. This merged frame will exist farther processed and optimized, in a move to reduce the artifacts resulting due to the earlier stages in this technique, and finally be sent to the screen. The frame N+one will pass to the next process pipeline, in order to act as the new frame N, and this takes place repeatedly. Well, that's pretty much the Checkerboard technique in a nutshell.
Checkerboard Rendered 4K vs Native 4K
Well, at first glance you lot'll discover it very difficult to notice the divergence between Natively Rendered and Checkerboard Rendered 4K footage. However, you practise discover a fair amount of divergence betwixt the ii, especially when you pause the rendered video and zoom in, merely to realize there are artifacts at the moving edges on a Checkerboard rendered 4K footage. Well, this is pretty much the only disadvantage of this technique every bit fast motion leaves a faint crisscross pattern, where but half the pixels are shaded. However, motility blur in the recent games tin can help a lot in hiding these artifacts, and the residue of the details are pin sharp, even with the compromise that it effectively halves the resolution upon 4K. All in all, it's barely noticeable to the human eye, and fifty-fifty if you do manage to notice it, information technology'southward not going to be a significant departure, especially considering the hardware that you need to spend your coin on, in society to return games at native 4K.

Is Checkerboard Rendering Good Plenty For You?
Well, this depends on your personal preferences and budget constraints. If y'all really want to push native 4K resolution for a glorious eye candy experience, we'll not finish you from shelling out thousands of dollars on edifice a high-end gaming rig. However, if yous're a console gamer or affordability is your summit priority, you will not exist disappointed with the Checkerboard rendered 4K footage that you lot get to experience on both the PS4 Pro and Xbox One X consoles. So, what practice y'all call up nigh this new technique used by the latest consoles? Are you satisfied or are yous still waiting on the next-generation consoles for a Native 4K gaming experience?
