Depends what you mean by 'needs'. The combination of dedicated ray tracing acceleration hardware and APIs to drive it with some remarkable advances in denoising, in part driven by deep learning plus associated dedicated hardware, means that we are at a threshold where hybrid techniques that mix rasterization with ray tracing are viable for games and can advance the state of the art in real time rendered image quality.
That certainly doesn't mean real time rendering is 'solved'. We could certainly use another 3 orders of magnitude compute performance (and more) if we had it to get better visuals. That's pretty much always been true for graphics though.
