Why does PS4 Pro not have an option for 60fps?

This is not correct.

It depends on the type of tasks.

Graphics, such as painting the geometry, shaders and polygons are heavily GPU dependent. A twice as fast GPU can render images roughly twice as fast, but the increased amount of draw calls required to do that by the CPU only increases the CPU load by 10% or so in a typical graphics intensive game, because most of the CPU tasks remain unchanged, such as calculations for AI, physics, scripts, user input etc.

So the PS4 Pro is perfectly balanced if the games remain within the same generation so to speak. It's designed so that you can double the framerate or resolution or other tasks that the GPU handles such as better lighting, anti-aliasing, filtering, shadows, post processing visual effects, but not for more complex physics (think Battlefield and it's destruction, which is calculated by the CPU) or AI and world systems (think all the behaviour, interaction and position of units in an RTS, or all the world simulation, stats and items that are handled by the CPU in Skyrim).

We were talking about CPU tasks specifically.What you said about GPU task is right just not what we were talking.

PS4 PRO GPU allows better resolution and graphics but the 30% improvement on CPU won't be enough to push physics and AI calculation enough.As i said they could make workarounds to compensate that(GPGPU comes to mind) but that would require some extra care(time,money and effort) that devs are not willing to do for a console(The reason they love consoles is because they only need to optimize to one spec)

No. You specifically claimed that a doubled framerate requires a double the CPU power.

"This 30% improvement is not enough to allow twice the physics/AI calculations per second.(which is required to have twice the framerate)"
"double the framerate -> double the amount of data  to process on the cpu in the same time frame,thus,double the clock is needed"

But it's simply not correct.

Physics and AI scripts aren't tied to framerate in modern games, but graphics are.
(physics can be synced with framerate like in Dark Souls 2, but it's a different thing)

The CPU uses the same amount of calculations for the physics and the AI no matter if the framerate is 30 or 60.

If want to run Witcher 3 in 60fps instead of 30fps, I need roughly twice the GPU power, but only about 10% more CPU power (and the extra 10% are for the increased amount of draw calls for to the GPU, not to calculate extra physics or AI).
