Thanks for proving my point, you showed a 13 year difference range.
The difference isn't that big, and that's just one game.
GTA VI isn't even out yet, nor we have seen real time gameplay.
Not mention, decades of work and hundreds of millions thrown into it.
2 years worth of time back then created bigger jumps than decades worth of time today.
There's a reason many don't even consider the PS5 that big of a jump, over the PS4.
Diminishing returns
In fact, many PS5 games ARE PS4 games with the settings turned a little higher.
