Overview
- Nvidia made DLSS 4.5 Ray Reconstruction available via the NVIDIA App DLSS Override on Tuesday, letting GeForce RTX owners enable the new model in supported games without waiting for native patches.
- The feature uses a second‑generation Transformer that unifies denoising and Super Resolution to reconstruct cleaner ray‑traced and path‑traced lighting, with Nvidia saying the model uses about 35% more compute and 20% more parameters while keeping similar performance to prior versions.
- About 30 games support the override at launch, including Cyberpunk 2077, Alan Wake 2 and Resident Evil Requiem, and Nvidia published a full day‑one list users can toggle in the GeForce App.
- Developers get an updated DLSS SDK with finer temporal‑accumulation controls and RTX Remix support so studios and modders can integrate Ray Reconstruction natively or add it to remasters and mods.
- Nvidia says the release completes the DLSS 4.5 suite and could speed adoption of higher‑quality ray and path tracing, though real‑world benefit will depend on players’ GPU power and how studios tune the model in native updates.
