Sony files patent to speed up raytracing on PlayStation 5

sony registered a new patent of what appears to be a method to speed up ray tracing performance in PlayStation 5 games.

Sued by Mark Cerny, the chief engineer in charge of the PlayStation 5 and PlayStation 4, the patent is titled “system and method for accelerated ray transmission with incrone operation and ray transformation.”

The idea would be to use shader processors to adjust the rays, increasing overall performance when the ray tracing feature is enabled. The patent itself explains that “the processing strategy can lead to a significant increase in the transmission speed of the rays, since the shaders program only performs impact tests”.


Real-time ray tracing has been converted into a fashionable graphics technology, following its mainstream introduction with Nvidia’s RTX cards. Subsequently, both PlayStation 5 and Xbox Series X apostatized ray-tracing as one of its versuss, sometimes in titles like Spider-Man: Miles Morales or Ratchet & Clank: A Apart Dimension, in the case of Japanese society.

Without restriction, the computational requirements that implement this technology in all games always result in very expensive results. Gran Turismo 7, for example, hasn’t enabled it in races and will only be used in rehearsals and car viewing modes.
