  "account": "Nvidia has rolled out an updated version of Ray Reconstruction with its DLSS 4.5 technology and after thorough testing, we have found that it delivers high upscaling quality while reducing artifacts caused by ray tracing. This new model boasts a more efficient design, providing 35% more compute capability and handling 20% more parameters than its predecessor. Furthermore, it has been trained on a larger dataset, marking the third iteration of Ray Reconstruction. Nvidia claims that the new model maintains its performance without any impact. GeForce RTX users can now take advantage of this feature right away. DLSS 4.5 Ray Reconstruction is the latest advancement in Nvidia's AI-based denoiser for ray tracing, built upon the second-gen transformer architecture introduced with DLSS 4.5 Super Resolution. It combines the functionalities of an upscaler and denoiser into a single model. However, enabling Ray Reconstruction alongside DLSS upscaling bypasses the normal upscaling pass, allowing the system to handle both upscaling and denoising simultaneously. This development is crucial as Ray Reconstruction does not simply function as a denoiser. With Ray Reconstruction's integration, Nvidia has eliminated performance disparities between Super Resolution and Ray Reconstruction. The new model can be enabled via the Nvidia App's DLSS override settings, with Preset F representing the new DLSS 4.5 model and Preset D from DLSS 4.0 being another option. Using DLSS 4.5 Ray Reconstruction in combination with upscaling improves the upscaling quality, bridging the gap between the two. Key enhancements include sharper images, better handling of disocclusion, and improved foliage reconstruction. While Ray Reconstruction reduces noise and improves lighting quality, there is only one model to choose from, unlike DLSS 4.5 Super Resolution, which offers Preset M and Preset L.",
