In Summary,

At this stage (as a first generation game) and graphic fidelity of Killzone 4, Playstation 4 can handle
-1080p and 30 fps
-somewhat less than 1080p (up to 50% less) and 60 fps
but cannot currently handle
-1080p and 60 fps
They obviously opted for better performance on the fast paced multiplayer, which I believe was the right choice.

Of course, with a reduced graphics load, it is a no brainer to handle 1080p & 60 fps, but this is a true generational leap here. Here comes the real challenge:
- To keep the same level of fidelity at 1080p & 60 fps,
which I believe will be succeeded in 1 or 2 generations, however,
- Developers may choose the opt out for even better graphics at 30 fps

Well "sub-cores" is not an official term either I think.   the SPE and PPE have different roles in the OS/hardware environment, like which one boots first and which one is the master/slave.  The PS3 uses the PPE's support for hypervisor/kernel/user protection model.  The kernels in use on SPEs are much simpler as they don't have to run the full real-time OS, they just run tasks.

At the end of the day though the SPEs are just a type of general logic core.  Both the PPE and SPE are 3.2GHz dual-issue RISC cores.

Killzone Shadow Fall look stunning PERIOD(MP and SP)!, I lol at those haters nitpickers trying to convince the opposite.

But they can keep trying they are very amusing :D

It's even more complex than expected. That's really cool.

Also the ignorance in this thread is too dang high. Shockingly the "PS4 is underpowered" comments aren't that bad. It's the "dat damage control" and "that aint 1080p" comments that are wack. When given a moderately detailed explanation by an expert that someone's wrong on something precise like computer rendering, it takes a special type of person to shout back "no you're wrong!"

From what I am gathering from doing a little research on google, they are not general logic cores. I never really bothered with any of the specs for last gen systems and you may be correct. But I can't find anything that says they are general logic cores. They also use a specifically developed instruction set.

360 fans? and I agree with you, they are doing a lot of damage control as it does not fit their agenda anymore :)

it does indeed look stunning, OMG at starting chapter 9 you just cant believe your seeing such visuals

its not just visuals but the level geometry its mind blowing, when you take elevator upto stalh just look around you all the pilings and girders that are rendered ive not seen another game like it, theres other stages in game that are like that especially in vekta city

re: the multiplayer issues that have been brought up it doesnt detract from the experiance but i would have preferred them to lock it at 30fps, i dont believe for a min that slow paced titles like this need to be 60fps

So this technique was use to get to 60fps , to get rid of the latency and lag so it feels smooth like a normal 60fps multiplayer game. Funny that ,, because despite using the technique,, the character in which you have control of,, feels liek they have an anchor tied ot their legs. The whole aiming feels very heavy. This is based on my experience as i have also tried titanfall beta and it deosn't even come close to that level of smoothness.

@ICstats--- The game in multiplayer never reaches 60fps. The highest it goes to is 50fps. Check df. The multiplayer in kz also drops as low as 32 fps a second ,, even dips to 40 frames. Its never consistent at 50fps. All of it can be found in detail on DF.

Based on the definition of a core, they are a core.  Sure they may be missing a few things most "full" cores have, but the parts that are required for it to be considered a "Core" are there.

As for the resolution thing, it is 1080p.  All games render certain onscreen things at resolutions lower than the main one.  For instance Borderlands 2 on PC renders shadows in 720p (Like Killzone SF does).  Does that mean BL2 isn't in 1080p on PC?  No!
