Final week AMD launched FSR 4 alongside its first RDNA 4-equipped desktop GPUs. It is a drastic enchancment over earlier variations of the tech suite, introducing AI-powered upscaling that’s solely doable due to devoted {hardware} on the brand new playing cards. It is an development that Sony’s Mark Cerny is saying will come to PS5, albeit not till 2026.
Talking to Digital Foundry, Cerny was stuffed with reward for AMD’s FSR 4 launch, saying that the upscaler surpasses the work Sony has achieved with its PS5 Professional-exclusive resolution, PSSR. “And outcomes are wonderful, it is a extra superior method that may exceed the crispness of PSSR,” Cerny defined. “I am very happy with the work of the joint crew!”
Cerny says that FSR 4 will should be backported to the PS5 Professional, primarily by a brand new model of PSSR that takes under consideration all of the developments AMD has made. Cerny says that for essentially the most half the data the upscaler requires from a recreation will keep the identical, which is able to make implementation by builders simpler, however that it is not as straightforward as supporting FSR 4 natively. That is as a result of PS5 Professional having a completely totally different structure than RDNA 4, and thus not one that may help it totally like AMD’s newest GPUs.
“RDNA 4 and the {hardware} in PS5 Professional are fully separate designs, which is why I communicate when it comes to ‘reimplementation’ on PS5 Professional after I speak concerning the new upscaling community utilized in FSR 4,” Cerny continued. “I am positively wanting ahead to a future with co-developed {hardware} options for machine studying that can dramatically enhance the interoperability.”
FSR 4 does not have the identical efficiency good points as its earlier iteration, partially as a result of further overhead required for the vastly improved outcomes. Cerny, nevertheless, believes the PS5 Professional can nonetheless help these picture enhancements regardless of the a lot weaker {hardware} within the PS5 Professional, with out requiring main re-architecture. “That’s what we’re concentrating on, and we imagine we will obtain it,” Cerny added.
Sony and AMD proceed to collaborate on Mission Amethyst, with its first main milestone coming with the discharge of PSSR. Cerny believes there’s much more to come back by working carefully with AMD, particularly in relation to machine studying and ray tracing enhancements for future console {hardware}. “All I can say is keep tuned! There’s numerous alternative with our Amethyst collaboration, and we all know that ray tracing is a large a part of the graphics future,” concluded Cerny.
