Polyphony, the guys behind the Gran Turismo series, recently took to the stage at the SIGGRAPH Asia 2018 industry event (which showcases the latest in computer graphics and techniques) to reveal that they have been secretly working on their own version of real-time ray tracing.
Real-time ray tracing (which has been the stuff of dreams until the release of NVIDIA’s RTX 20-series) provides authentic looking shadows and reflections courtesy of the game engine tracing the rays of light as it bounces off the many different objects in a scene.
The (admittedly poor quality) video below, via wccftech, demonstrates the advanced lighting and reflections in what we can only assume to be a Gran Turismo Sport build of some sort, see for yourself below (starting at 7:25).
It’s certainly a big step up from Gran Turismo Sport‘s current and somewhat rudimentary reflections system. Whether or not we’ll see this real-time ray tracing technology in the next generation of Gran Turismo titles on the PlayStation 5 remains to be seen. One thing is certain though: Polyphony will continue to drop our jaws in the visuals department when it comes to Gran Turismo.
