i just watched the first 5 minutes of the first video clip and didn't realize ray tracing is more complicated than i thought. i also watched like nearly a minute of the part where it compares a human face with nvidia nrd denoiser and one with dlss 3.5 ray reconstruction. interesting.
i just watched the whole trailer of the 2nd clip since its pretty short.
on the 3rd and last video clip, i just watched 3:33 mimutes of it only since its too long. quite interesting though.
