how emulators struggle with frames per second so much?

After the recent news of people running bloodborne on PC on a ps4 emulator at a massive 1 frame per second, I’m just wondering why they tend to struggle to run these games?

Hardware, especially graphics hardware (GPU), is super optimised. An emulator basically replicates this in software on more generalised hardware (CPU) this is massively less efficient.

As this is ELI5 let me use an example:

Think about a calculator, dividing large numbers is very fast if you use it. You can do the same thing in your head or with a pencil on paper. It will just take more time.

Running anything/bloodborne on computers is, this is a fast oversimplification, just doing a lot of math.

Running bloodborne on the original hardware is like using the calculator. Running it in an emulator is like using a pencil and paper.

Does this help ?
