Realtime ray tracing will take us there and this is the first hardware generation to offer dedicated hardware acceleration for that which makes it practical for games for the first time. Don't expect things to change over night though, it will be a while before this hardware is mainstream and a while before rendering engines are designed around it. We'll see hybrid rendering approaches first and there's no upper limit on the horizon for the amount of compute that can be burned to improve visuals.
