yeah, Sony should just drop all those 80+ million ps3 owners because you say so

Agreed. Rather have steady 60 fps and decent graphics than great graphics with 30 fps.

Graphically, I think ps4 games look good enough. The ps4 architect favours graphics over frame rate from what I understand.

Seems like the clock speed of its CPU is a generation behind its GPU.

Those are two orthogonal things to each other.

Dynamic lighting typically refers to full shading and lighting of the scene in real-time, with minimal pre-computation. The contrast to that is static lighting, whereby offline processing of the scene is carried out to help reduce the real-time burden, and even has the potential for improving apparent quality far beyond what may be possible at real-time (e.g. ray traced light maps providing extremely high quality occlusion and shadowing). This generally applies to lighting and/or geometry that won't move though, which is it's primary limitation.

Physically-based rendering (aka. 'PBR') is related to how we compute values for light interaction about the scene.

Taking after the film industry, in the last few years the game industry have been moving towards treating light and materials in a more physically-correct manner. That is to say we want to be more accurate in calculating values for light reflectance (diffuse and specular) and refraction (scattering, transmittance, absorbance), although games focus more on accurate, by considering the unique micro-surface properties different materials may have, as well as better 'descriptions' for real-world lighting. Prior to this, being "physically-correct" was rarely tackled, relying mostly on artist-provided properties along with fairly simple shading and lighting, all of which can result in unrealistic and implausible results in varying conditions.

The effect of moving to PBR means that instead of relying on artists to provide both light and material properties, more physically-plausible values are used by taking from real world data. This, along with more complex and accurate shaders, allows for greater control and realism, whilst also easing the development burden of content creation (search 'Quixel' or 'Allegorithmic Substance') because such data is effectively re-usable.

That's a very simple explanation of it mind. If you want a more detailed explanation check the Marmoset website.

I'd love another Infamous. You can't have too much Infamous. It's the perfect game really.
