What is ray tracing on PS5? Every time that Sony has brought up the PlayStation 5, it's also mentioned ray tracing, using the term as a selling point. But just what is ray tracing, and what does it bring to Sony's next-gen console? Without getting too technical, we're going to answer that question in this very guide.
What is PS5 Ray Tracing?
First off, we need to understand what ray tracing actually is. Ray tracing is essentially a method of simulating realistic light in computer graphics. A slightly more detailed explanation is that ray tracing simulates the "path" light takes when it interacts with open spaces and objects. This allows for light to have a "volume" to it -- something that you don't necessarily get from generic light sources in video games.
Ray tracing allows for light to interact with its surroundings in a dynamic and natural way. For example, a ray of sunlight shining through an apartment window in Grand Theft Auto V is basically just a block of light. It casts shadows and it moves based on the in-game time of day, but that's about it. With ray tracing, that ray of sunlight "fills" the space that it enters -- it's no longer just a block, it's a dynamic shape that changes and interacts with surfaces based on where it's coming from and the angle that it enters the room.
This video showcasing a PC mod for Grand Theft Auto V is a great example of how ray tracing can improve lighting effects in video games:
However, as you'd expect, ray tracing can be quite demanding. Mostly used in film, it's not something that you see in current video games on consoles, but with the power of the PS5, ray tracing could become lot more commonplace. While ray tracing is certainly being pushed as a next-gen buzzword by companies like Sony, the technology is undeniably impressive. Hopefully we get to see the PS5's ray tracing capabilities in action when the console is fully revealed.
