Ray tracing simulates the way that light bounces around a scene and interacts with objects before entering our eyes to create the image of the world around us. It’s the kind of CGI rendering approach used in blockbuster movie graphics, and the same technology that allows architects to create truly photorealistic images of buildings which haven’t yet been built. But for a long time ray tracing has been far too slow for practical use in gaming, because where complex movie CGI might take minutes or even hours to render just one frame, the gaming baseline is about 30 frames per second. Thanks to NVIDIA’s GeForce RTX GPUs, Battlefield V shows what real-time ray tracing capabilities mean for gaming graphics.
