Players chasing realistic lighting and reflections in games often run into the same frustrations. Ray tracing looks impressive in theory because it simulates how light actually bounces around a scene. In practice, engines fire fewer rays than ideal to protect frame rates, which leaves behind grainy noise that older cleanup tools struggle to fix without blurring details or creating odd trails behind moving objects. NVIDIA addressed those issues with a new version of its Ray Reconstruction feature inside the DLSS family. The update relies on a second generation transformer model trained on far more data than before. It processes 20 percent more parameters and handles 35 percent more computations internally, yet it keeps performance roughly in line with the previous release.
