Comparisons show that ray tracing primarily affects global illumination and reflections. In some scenes, the difference becomes especially noticeable and changes the overall perception of the image.
The greatest effect is seen in enclosed locations and night scenes with multiple light sources. Here, global illumination makes the image more natural and realistic. Without ray tracing, visual problems are noticeable in interiors, which disappear after enabling the technology.
Additionally, ray reconstruction in DLSS improves the quality. It increases the sharpness and stability of the image. As a result, the picture looks more complete and "cinematic," especially in motion.
All of this indicates that Crimson Desert was initially created with ray tracing in mind. If you have the right "hardware," the difference is really noticeable.
