Overview
- CD Projekt Red will integrate a foliage-focused iteration of RTX Mega Geometry that combines geometry clustering with opacity micromaps to speed up leaf-heavy ray tracing.
- Nvidia says the method partitions the top-level ray tracing structure and selectively updates it each frame to reduce CPU overhead in dense, Nanite-based UE5 environments.
- Demo footage shown alongside the announcement depicts millions of forest objects rendered with accurate lighting and shadows at what Nvidia describes as game-ready performance.
- The technology remains supported across all RTX GPUs, with additional hardware acceleration available on Blackwell-based GeForce RTX 50 cards.
- Earlier real-world use delivered measurable gains, including a 5–20% FPS uptick and about 300 MB lower VRAM usage in Alan Wake 2, with further adoption confirmed for Control Resonant.
