It is more than evident that the next generation console from Sony, the PlayStation 5 lack the muscles to offer the promised 4K @ 120 FPS, but to target 4K @ 60 FPS, the company could keep an Ace up its sleeve to achieve high resolutions with a higher and more stable frame rate in the future with the help of technology similar to Nvidia DLSS (Deep Learning Super Sampling).
This has been disclosed thanks to a patent registered by the company last year, but which has come to light until a few days ago. Unfortunately the patent is in Japanese, so there are still many details that are unknown, but the important thing is that it indicates:
“An information processing device for acquiring a plurality of reference images obtained by imaging an object that is to be reproduced, acquiring a plurality of converted images obtained by enlarging or shrinking each of the plurality of reference images, executing machine learning using a plurality of images to be learned, as teaching data, that include the plurality of converted images, and generating pre-learned data that is used for generating a reproduction image that represents the appearance of the object.”
Yes, even in translated form it sounds like Japanese. Although at the beginning of its launch Nvidia’s technology was classified as a failure, with the passage of time and the implementation of improvements, DLSS has become essential today to enjoy the highest possible visual quality of a game without performance being a problem, so if Sony implements a technology as good as for example DLSS 2.0, this will allow the console to run like a fish under water in 4K resolutions.
