RTX, or Ray Tracing Technology, is a rendering technique used in computer graphics to simulate realistic lighting, shadows, and reflections. It enhances visual quality in video games and animations by mimicking how light interacts with objects in the real world. This technology is particularly popular in high-end graphics cards, such as those produced by NVIDIA. The NVIDIA RTX series of graphics cards incorporates this technology, allowing for more immersive gaming experiences. By using dedicated hardware for ray tracing, these cards can deliver stunning visuals while maintaining high performance. This advancement has made RTX a key feature in modern gaming and visual effects.
