Large-scale natural environments, like forests, remain a difficult challenge for real-time ray tracing. Such scenes demand high numbers of objects with complex geometry, combined with continuous animation. This comes at a significant cost to optimizing scene geometry and ray tracing performance, as well as VRAM requirements.
Last year, we debuted NVIDIA RTX Mega Geometry in Alan Wake 2, improving frame rates and reducing VRAM usage in its foliage-filled environments. By compressing geometry into clusters, RTX Mega Geometry handles massive scenes and updates them up to 100x faster than previous methods, enabling full‑fidelity path tracing with advanced detail and real‑time tessellation. Later this year, RTX Mega Geometry will also be coming to CONTROL Resonant.
At GDC, we announced a collaboration with CD PROJEKT RED to integrate a new NVIDIA RTX Mega Geometry foliage system into The Witcher 4, their massively anticipated open-world role-playing game.
Featuring a new level-of-detail system for foliage, the technology selectively updates scenes, reducing memory usage and accelerating performance in a visually-seamless manner. With this, for the first time, we can path trace dense environments with millions of detailed plants and trees, unique animation, and accurate real-time lighting and shadows.
Take a first look at the NVIDIA RTX Mega Geometry foliage system in our new, exclusive video:
