Yesterday, Sony took the wraps off its PlayStation 4 Pro, in what was undoubtedly meant as an exciting launch unveil simply came across equally rather confused, instead. In that location'southward been a lot of chatter over what the PS4 Pro can and can't evangelize with regards to 4K, so let's unpack that question.

The GPU within the PS4 Pro is widely believed to be a downclocked variant of AMD's RX 480 running at 911MHz. This GPU is substantially more than powerful than the PlayStation 4's GPU, with twice the CUs and a higher clock rate. It's admittedly capable of delivering much improve performance than the PlayStation iv could. But can it button 4K? That's a more than complicated question than information technology might seem.

The consumer 4K standard (technically it'southward 3840×2160) refers to the number of pixels being drawn on-screen. Information technology's not an intrinsic epitome quality metric and it doesn't say anything well-nigh the level of detail in a given title. There are enough of PC titles from multiple generations that volition happily display themselves in 4K (whether their menus, UIs, or other elements will be legible in that style volition depend on the championship, but the game itself will render at native 4K). When Sony says the PS4 is capable of 4K output information technology doesn't tell us anything about the kinds of games that the PS4 Pro can render in 4K or the detail levels they'll offer when using that mode.

Naughty Dog, for example, has promised that The Concluding of United states will run at 4K native resolution on the PS4 Pro. But — and this is disquisitional — the Concluding of U.s.a. is originally a PS3 title, and while Naughty Domestic dog fabricated some substantial improvements and enhancements to the game when it shipped on the PS4, it was nonetheless congenital with a last-gen console in mind. The screenshots above testify the departure betwixt the 1080p@60Hz version of the game that shipped for PS4 and the 30 FPS, 720p version that debuted on the PS3. Some scenes bear witness significant differences while others are quite similar.The Last of U.s.a. for the PS4 Pro will accept at to the lowest degree ii dissimilar flavors: A native 4K version with farther graphics enhancements locked to a xxx FPS frame rate and a lower resolution version that volition run at a steady 60 FPS.

How to render 4K (without rendering 4K)

Naughty Canis familiaris may be able to push The Last of Us upward to a native 4K resolution thanks to its roots in PS3-era graphics, simply what almost upcoming titles? Hither, Eurogamer thinks they've found the reply. I potential technique discussed by Valve's Alex Vandros involves using a checkerboard design to reduce the particular level and save bandwidth in VR.

I'm not as confident as Eurogamer that the slides to a higher place really refer to the same checkerboard pattern Sony patently mentions in the PS4 Pro'southward documentation. Valve'south Alex Vandros was referring specifically to VR and looking for ways to trim detail in areas the eye isn't focused on. This works considering it exploits how the eye focuses on specific areas of the screen, but the same technique may non be adaptable to a 4K flat console.

Upscaling seems simple: It'southward the process of taking an image or video recorded in 1 resolution and scaling it up to a higher resolution. A practiced upscaler tin accept a 1080p signal and output it at 4K. It may never look quite equally good as a native 4K output, but whether or not you'll see the difference depends on a number of factors, including the capabilities of your television receiver and how far you lot sit down from the screen.

The screenshot to a higher place compares native 4K versus rescaled methods and comes from this commodity on the claim and uses of 4K compared with conventional 1080p. While the commodity focuses on shooting and editing video in 4K, many of its points near fine levels of particular and scaling artifacts are conceptually relevant to gaming. Upscaling is a way to capture a "good enough" level of particular without going all-out to return (or capture) huge amounts of content that the end user ultimately won't come across.

Actual developers have been coy near how they're going to deliver 4K content to the PS4 Pro. Johan Anderrson claims that Frostbite 3 is using a custom method of delivering 4K that's neither native "or" upscaled but something altogether different.

Nosotros'll take to wait to find out how all these pieces fit together, but it's clear that the games Sony showcased as being 4K-capable aren't all rendering at that resolution natively. That may carp some purists, but I'grand not one of them. From my vantage point every bit a PC gamer, the dropped frames and inconsistent frame rates that have plagued both the Xbox One and PS4 this cycle are far more damaging than any small resolution differences. I'one thousand a PC gamer because I like choosing my ain merchandise-offs when I have to residue detail levels and frame rates — just if I have to cull between them, I'd take a rock-solid 60 or even 30 FPS over higher detail levels with increased stutter.

Sony is going to give gamers more options to choose what kind of experience they want to have with the PS4 Pro, provided they own the right hardware in the outset place — only that's a subject for its own article. Early feedback from reporters who tested the PS4 Pro has been mixed, but there's full general agreement that if you own a UHD TV with HDR enabled you can look forward to a much nicer picture — while players with 1080p displays and standard display resolutions should relish better performance. Exactly how much amend is still unclear, feedback on that forepart has been mixed. Either mode, the PS4 Pro (mostly) won't be pushing native 4K with its upgraded GPU. We don't think that's going to be a problem, provided the boosts to graphics quality are high enough in general.
