Solid neighbourhood-bakery energy. Trustworthy and warm.
Summary
NVIDIA announced the 2nd Generation Ray Reconstruction as part of DLSS 4.5. Originally launched in 2023 with DLSS 3.5, Ray Reconstruction fixed image quality issues with ray traced shadows and reflections under DLSS 2 super resolution. In 2025, NVIDIA upgraded from CNN-based AI models to transformer-based models, and the DLSS 4.5 feature set includes 2nd Gen transformer models trained on larger datasets. However, the article appears to cut off before completing details about Ray Reconstruction's status in this update.
