Just a couple of days ago, Sony announced its much rumored and anticipated console, PlayStation 4 Pro. Since its reveal many developers have shared their thoughts about what it means for the future of gaming. While the console does not support native 4K, it almost outputs quality similar to 4K and Digital Foundry has explained how this console does this.
Digital Foundry has detailed their first impressions of the PlayStation 4 Pro and also explained how this console manages to output 4K.
According to them, Sony has used a technique called checkerboard process, which uses a 2×2 pixel block and extrapolate a 4×4 pixel block from it.
This technique allows developers “to construct a 2160p 4K framebuffer from half the pixels – a much closer fit for the Pro’s GPU prowess”.
They further added that while this technique is hardware related, but game developers will also have some control over it, which explains why different games have different levels of artefacting.
We also understand that while it is a hardware feature, game-makers do seem to have a certain level of control – which may perhaps explain why different games exhibit varying levels of artefacting. But the key takeaway is this – while the PlayStation 4 Pro GPU lacks the horsepower to render out challenging content at native 4K, the presentation we’ve seen on a number of titles clearly shows a worthwhile, highly desirable increase in fidelity over 1080p – one that does put a 4K screen to good use. Switching between full HD and checkerboard 4K, the increase in detail is simply stunning.
While the console will not offer a native 4K resolution, but it will offer a quality closer to it. However, it is important to note that the technique used by Sony to upscale the resolution is quite similar to that of Remedy’s which was used in Quantum Break to upscale resolution to 1080p.
PlayStation 4 Pro is ready to launch on November 10, 2016 and will be available for $399.
