I tested NVIDIA’s new DLSS 4.5 Ray Reconstruction — it finally fixes path tracing’s biggest flaw, but here’s the reality check

NVIDIA has debuted DLSS 4.5 Ray Reconstruction, featuring second-gen AI denoising. This new AI transformer model specifically targets path tracing noise and ghosting on RTX 50-series systems. While the technology provides marked improvements in ray-traced lighting effects across most game scenes, it is not considered as transformative as previous DLSS iterations. Testing indicates that it finally addresses the primary flaw of path tracing, though the overall impact on the gaming community remains measured.
