Sony seems to be engaged on methods to enhance ray tracing on PS5, in keeping with an inventory on the Sony Group Portal web site and a lately filed patent.
If you happen to’re not conversant in ray tracing, the best solution to describe it's a more superior and lifelike means of rendering mild, shadows, and reflections in a scene. Ray tracing is often utilized in motion pictures and TV reveals, and its software in video games is now attainable because of more highly effective {hardware}.Nonetheless, ray tracing is an especially graphically intense characteristic that always requires builders to decrease a recreation’s efficiency and determination to implement it successfully on PS5. This has been the case in video games like Cyberpunk 2077, Dying Gentle 2, Management Final Version, and Marvel’s Spider-Man: Miles Morales, although developer Insomniac does supply a Efficiency RT mode, which features a decrease constancy type of ray tracing however retains the body charge at 60fps.
Sony, then, appears to be attempting to handle the toll that ray tracing can have on a developer’s assets. A submit on Sony Group’s website highlights a brand new AI know-how, which may enhance efficiency in PS5 video games. Takafumi Morifuji, a lead researcher at Sony Group Company, is exploring super-resolution know-how in ray tracing, which primarily depends on machine studying to make decrease decision photographs sharper and more clear.
Though the brand new AI know-how is presently solely being examined in CG motion pictures, Morifuji says that super-resolution ray tracing could have a “large effect in the future”, and “the aim is to extend the use of technology to games, movies, and other areas of entertainment.” There’s no purpose why, then, we couldn’t finally see super-resolution know-how in ray tracing be used on PS5.
One other signal that Sony is taking ray tracing significantly comes through a lately noticed patent filed by Sony’s lead system architect, Mark Cerny. Cerny filed a patent for “System and method for accelerated ray tracing” on August 20, 2020 (thanks, Zuby_Tech), which factors to a brand new means of optimizing ray tracing results on PS5.
Whereas it’s laborious to parse by means of all of the technical language used, it seems that the brand new patent would successfully scale back the variety of rays that should be forged in-game, lowering the assets wanted for ray tracing whereas nonetheless delivering a comparable expertise.
Evaluation: ray tracing wants a lift
(Picture credit score: Treatment)It’s clear that regardless that ray tracing is a fascinating characteristic, it presently takes an excessive amount of processing energy to be as mainstream as some may like. If Sony can discover a solution to optimize ray tracing or use upscaling strategies to supply higher picture high quality when decision or body charge does should be compromised, it may make the characteristic a more tempting proposition for builders and avid gamers alike.
Presently, solely these with entry to high-end GPUs just like the Nvidia 3090 can actually get essentially the most out of ray tracing, together with the usage of Nvidia's DLSS know-how which makes use of AI to upscale decrease decision content material, just like what Sony is proposing with its machine studying tech.
However why do we want ray tracing, precisely? Though builders have mastered the artwork of making convincing lighting in video games, it’s a time-intensive course of that may’t replicate the identical degree of realism that ray tracing can present. The identical is true of reflections and shadows.
Here’s hoping ray tracing continues to be improved sooner or later, significantly on consoles like PS5, because it’s a know-how that may have a very transformative impact.
