The IO speeds of the consoles doesnt effect frame rates. (thats basically a stupid question)
*(unless you try to load more, than the IO speeds can keep upwith)

That comes down to the CPU & GPU.

The IO speeds of the Playstation 5, is more about whats possible to be shown on screen (complexity of textures) and the stress that puts on the IO & Drive. The speeds of the SSD allows for higher quality assets to be loaded, and streamed in as your moveing around ingame.
This would be a limiting factor on the PS4 or XB1, and wont be on the Playstation 5.

higher FPS with the same quality assets has a higher strain on system memory doesn't it?

System memory (bandwidth) is much faster than the speed of SSDs (448 GB/s vs 9 GB/s (ssd)).
So the first issue with loading all these big detailed textures is actually the hard drives (SSDs and their IOs).

FPS is just a matter of how fast your GPU can render the geometry on the screen.
The higher the resolution the more demanding.

But what we re talking about, is the stuff that happend BEFORE the gpu renders a scene.


The quality the assets are loaded with doesnt nessarily strain the memory more than ones that arnt super detailed.
However starting with higher quality assets, does have visual benefits.
Its part of why the UE demo was so impressive visually.
