Epic Games today showed off an amazing real-time lighting demo in Unreal Engine 4 featuring the new Porsche 911 Speedster concept car. Best of all, the demo ran on a pair of Nvidia’s just-revealed Turing RTX graphics cards, showcasing the hardware’s real-time ray tracing capabilities.

The Porsche 911 Speedster concept car is the first vehicle to be visualized with real-time ray tracing, a graphics feature that renders photo-realistic lighting and reflections.
