Large-scale pure environments, like forests, stay a tough problem for real-time ray tracing. Such scenes demand excessive numbers of objects with advanced geometry, mixed with steady animation. This comes at a major value to optimizing scene geometry and ray tracing efficiency, in addition to VRAM necessities.
Last 12 months, we debuted NVIDIA RTX Mega Geometry in Alan Wake 2, enhancing body charges and lowering VRAM utilization in its foliage-filled environments. By compressing geometry into clusters, RTX Mega Geometry handles huge scenes and updates them as much as 100x sooner than earlier strategies, enabling full‑constancy path tracing with superior element and actual‑time tessellation. Later this 12 months, RTX Mega Geometry may also be coming to CONTROL Resonant.
At GDC, we introduced a collaboration with CD PROJEKT RED to combine a brand new NVIDIA RTX Mega Geometry foliage system into The Witcher 4, their massively anticipated open-world role-playing sport.
Featuring a brand new level-of-detail system for foliage, the know-how selectively updates scenes, lowering reminiscence utilization and accelerating efficiency in a visually-seamless method. With this, for the primary time, we will path hint dense environments with hundreds of thousands of detailed crops and timber, distinctive animation, and correct real-time lighting and shadows.
Take a primary have a look at the NVIDIA RTX Mega Geometry foliage system in our new, unique video:
