Ancient-Red-Dragon: Sure, but so what?...propaganda videos always do. Such videos don't mean jack all, and most likely will have zero relation to what the actual reality will be when the consumer tries to replicate the same results on their home system in the real-world.
I wouldn't call a tech-promo video propaganda but I said similar stuff than you anyway. Though testing shaders it requires engines designed to make this stuff work so you need games that enable so the brute force GPUs can work their wonders with the shadertech, so to speak. I'm fairly sure that the result actually look prettier than what they show, considering we know how people already have fully established CPU/GPU based ray tracing in video games about two decades prior to the launch of the so called RTX, but the results were usually a CPU/GPU killing nightmare.
However, there is a possibility that I'm wrong here, considering if what nvidia said was true regarding to machine learning algorithms, which means that this tech is still on its way to really mature and I'm talking about around half a decade here.
