Not sure what relevance 2 years has in the context of a proposed/potential 10 year generation, but to answer the question, pretty much everything. A 4090/Ti will be nowhere close to "maxing out" RT effects, high frame rates at 4K, next-gen (or even current gen) VR headsets, or UE5 titles that take extensive advantage of nanite and lumen.
to me buying an expensive GPU is just waste of money ,because it will never be the "best" GPU, there is always better GPU out there, thus you are just wasting money chasing something "infinite"
and will never satisfied with the performance.
The pricing of PC hardware especially GPU is getting ridiculous, people tend to look at framerates rather than playing actual games and then whine when fps drops below 120.
PlayStation games ported to PC.
In 10 years the PS6 will have been released already and most GPUs currently being sold will be on the garbage.
RT, native 4K, Unreal 5 promises, that's all so 3 years ago, so uninspiring.
i dont see the point of buying expensive GPU just to run ported Playstation games, its not like textures and model suddenly become lifelike (unless someone modded it, but still its no longer original).
Probably just sharper textures, longer distance rendering, with better RT, particles, lumen whatever etc...., does not justify the price of a gaming PC hardware imo.
