*Polishes BanHammer*

Let's try and keep things nice and civil in here.

In general though, this is one isolated incident of one game. It's not saying that the PS4 "only" has 4.5GB to use. It's just inFamous does. And as we're in a new generation with such a power increase, what do you expect? 4.5GB is still 9 times more than before anyway...

Here are some cold hard facts.
Ram does not do ANY form of processing, it is there to cache important pieces of data that has been/will be processed because it faster than retreiving it from a mechanical/optical disc.
What makes your games ultimatly look pretty is the Central Processing Unit (Usually responsible for framebuffer effects in the graphics pipeline as well as things like Draw Cells and Physics.)
And the Graphics Processor which puts all the pretty pictures on your screen.

The fact of the matter is, the Xbox One could have quaddruple the amount of Ram and games will not look better than the Playstation 4, because the hardware responsible for rendering the imagry is significantly inferior.

Remember, RAM is not a deciding factor in a systems entire performance, there is so much more that fits into that puzzle.

As for the OS exploding in Ram counts, it's simple, last generation consoles would clear the Ram and "seperate" parts of the OS and treat them as applications, lets use the Xbox 360 as an example, you sit at the dash board then you navigate to the video section, the Xbox 360 then launches a "Video App".
It's not running it all in tandem, there are delays.
The next gen consoles are also doing far more in the background like recording of video (Needs to use Ram to buffer data before writing it to the hard drive) amongst other things.
Plus they are only young systems, Microsoft and Sony gave themselves some room for the OS footprint, remember you can give Ram back to the system but you cannot taketh away when it comes to the OS's chunk of the pie.

So while it's all well and goods to only use Ram numbers in your comparisons and claim the Xbox One is faster, well... It just simply isn't reality.

You made my day.

Again, the faster memory isn't the deciding factor, it's a factor yes, but ultimatly, it's the graphics/central processor that will make the Playstation 4 truly shine, I'm surprised by how people are so fixated on that one tiny factor of a system but fail to take into account the rest of it? You know... The hardware that is responsible for actually drawing and displaying and processing of the data to give you all the pretty pictures?

As for 720P vs 1080P for most it's not an issue.
A vast majority of televisions sold are the cheapest-of-the-cheap, which generally are only 720P (Or more accuratly 1366x768)
Then you need to take into account that 720P compared to 1080P depending on how far you sit away from the panel... Actually have zero difference, the eye can only discern a set amount of pixels depending on pixel size and distance you are viewing them from.
Consoles typically are found in loungeroom environments too, which are often viewed from a distance.

On a PC it's a different story, 1080P looks like molassas on a 27" screen because of the viewing distance and pixel density, 1440P/1600P/4k makes a stupidly massive difference.

Lets not forget either than the Playstation 4 does NOT always display games at full 1080P and it's not guarenteed to do so, by generations end I fully expect most games to be sub-1080P. - That's something you console gamers will just have to put up with, your fixed hardware platform doesn't allow you any kind of flexibility in that regard.

Perhaps you need glasses? Could help...

I don't know him and don't remember him but the op itself has a link in it and some sentences about ram sizes. I can't see an opinion in there.

Really? And even if (which is of course ridiculous), why do you keep posting for them? Ignore their ignorance against facts, done

First "defense" now "cheap insult". Keep them coming

Let's quit this here. It's of no use.
