NVIDIA DLSS 5, also known as DLSS 3D-Guided Neural Rendering, is an AI model integrated into the NVIDIA DLSS SDK that enhances lighting and material realism in real-time PC games on compatible GeForce RTX GPUs. The model is conditioned on the frame the game engine renders, preserving its geometry, textures, character identity, composition, and scene semantics while enhancing subsurface scattering, hair and foliage transmission, contact shadows, reflections, and global illumination. It processes frames causally, using engine-supplied motion vectors for temporal stability. Developers set independent Structure Intensity and Tone Intensity controls and apply automatic or engine-defined semantic masks to individual objects or scene regions. This runs alongside a high-frame-rate game at resolutions up to 4K on a single GeForce RTX 50-series GPU. DLSS 5 integrates into supported games through the NVIDIA DLSS SDK, with titles available starting September 3, 2026.
