I don't quite get your response. UE5 nanite(atomview) has surpassed detail level the human eye can discern (or even camera, with the copying a copy degradation issue now moot), and so can't really be improved upon. Neither nvidia or amd have matched the nanite/lumen real-time interactive engine demo by visual fidelity, yet.
The best they can achieve is parity to that detail level - at a higher resolution, with more dynamic forward rendering assets using HW RT and a frame-rate boost some time in the future- but picture quality is already so unreal
on PS5 and PC GPUs are behind, despite having GPUs that computationally destroy the PS5's GPU, which points to the IO solution being the paradigm shift.
If the future of PC gaming needs a nvidia 4000, AMD 7000 card to have an SSD surface mounted, then we are at least 5years away from that being a £200 card, which means PC gaming will have trailed the PS5(and likely the XsX) for 3 of those years - which will be when mid-gen refreshes hit IMHO.
