Nvidia has released an update to its Ray Reconstruction technology within DLSS 4.5. Designed to improve the rendering of ray-traced and path-traced lighting, the update focuses on increasing shadow accuracy and refining how light interacts with complex surfaces.
Quick Facts
- New Capabilities: The update utilizes a second generation Transformer architecture, offering improved spatial awareness and more efficient denoising.
- Performance: Nvidia states the new AI denoiser is more efficient, allowing scenes to be reconstructed faster while reducing visual artifacts like ghosting and shimmering.
- Availability: The tech will be integrated into 007: First Light on September 15, 2026, and Control Resonant on September 24, 2026.
During a press briefing, Nvidia demonstrated the update using Alan Wake 2. The comparison showed that shadows cast by window shutters appeared less blurry, and light reflections on detailed surfaces, such as trash bags, showed more distinct ripple patterns.
According to Nvidia, the DLSS 4.5 model is designed to be continuously trained to address specific visual issues reported by developers. The company noted that the inclusion of additional developer controls allows for more precise adjustments to lighting responsiveness and motion clarity in ray-traced environments.
