My god man! Please help yourself with some information before posting! Just think for a moment, what would be the difference between static ray tracing and simple cube map reflections?
Reflective surfaces in Battlefield V reflect anything that moves. Down to the tiny fire flares of rocket tales.
Right because Nvidia chose a PUDDLE, for that effect. Yet globals and other effects are missing. Turing can only do so much, while rdna2 can do much more. The demo shows how robust rdna2 is, over focused ray tracing, that Nvidia likes to boutique for players in puddles.
