Real-time Ray Tracing (RTT) is a technology that is used to create realistic graphics in video games and other applications. It is based on the principle of ray tracing, which allows you to create a more accurate and detailed picture than traditional rendering methods.

RTT works by creating a beam of light that travels through the scene and interacts with objects in it. This beam then bounces off objects and hits the player's eyes, creating an effect of depth and dimension. This allows for more realistic shadows, reflections, and other effects that cannot be achieved with traditional rendering methods.

RTT technology is used in many modern games such as Cyberpunk 2077, Assassin's Creed Valhalla and Doom Eternal. It allows you to create stunning visual effects and enhances the gameplay, making it more realistic and fun.
