Cyberpunk 2077 became a platform for demonstrating various NVIDIA technologies. The next installment in the "Witcher" franchise will also be able to please players with this.
NVIDIA RTX Mega Geometry will be added to The Witcher 4 — the technology "accelerates the construction of BVH models for systems with clustered geometry" (this data is used when calculating scenes with ray tracing).
Ray tracing can be used in scenes with very high load (the slide mentions "millions of objects") and good performance will be ensured.
The technology is designed to "improve the scalability of ray tracing in dense environments, when working with complex meshes and highly detailed objects."
