Real-time ray-tracing has been one of the key selling points of NVidia’s new RTX graphics cards – the technology won’t be exclusive to them, though!
At SIGGRAPH ASIA 2018, the newest technology in computer graphics were discussed and presented, and Gran Turismo‘s developer team has shown up here. They made their unique in-house real-time ray-tracing technology! Its earlier iteration is seen in Gran Turismo Sport, but there, the reflections on the cars were „pre-baked.” (Which means they weren’t rendered in real time – it’s a neat trick, though.)
The video below, which is, unfortunately, isn’t high-quality, shows the tech demo at 7:20 or so. Polyphony Digital hopes that the ray-tracing will be part of the next Gran Turismo game. AMD’s video cards currently do not support the technology, but they are working on it for 2019 – would this be one of the critical deciders behind the next-gen PlayStation’s launch window? (And it’s unlikely that after the PlayStation 4, Sony would swap over to NVidia technology – the Xbox One also uses AMD CPU/graphical chips, too…)
