I don't give a single thought which console is more powerful. I have a pc which is more powerful than both of them combined.

I'm buying consoles the first time in my life to play exclusives.

I'm getting both xboxone and ps4. And maybe wiiU later down the road.

If we really want to break down what is said in this tweet.  You have a guy who is not working on any development between the PS4 and X1.  He talked to some people who told him the difference between the X1 and PS4 is 50%.  Not knowing if the people he talked with are working on games between both hardware is hard to determine.  For all we know, the people he talked with heard something from someone else who then read something on a forum. 

Personally, I rather hear from developers who are actually working on both hardware.  Who actually have practical experience working with both development environment.  We probably will not get info from those people until the both the X1 and PS4 ship.

you said people can fly people can fly.

Typo? Or secret coded message? Hmmm...

Exactly. You said People can Fly twice xD

Uh oh. Seems like the truth came out.

As if it's possible to put a simple percentage on that.

Surely with customised parts and such each console will have strengths and weaknesses in different areas of computing and graphical performance... Sure maybe overall the PS4 is slightly more powereful but why do people have to give this amount of fuck.

btw I don't have a source or anything, but around the PS3 launch I remember it was supposedly capable of 2 Teraflops, wheras the PS4 is supposedly only 1.8... perhaps I am getting wires crossed between theoretical and real performance here (though I thought floating point performance was only theoretical)

hes gone more indepth(he posted on neogaf):

Here I am. So...

1. I am not doing a damage control, but I do want to clarify one thing. But first, yes, devs I know -- and as someone has shown it before in this thread, some other devs already talked about it too -- claim that there's 50% speed difference WHEN DEVELOPING in cross-gen/next-gen PS4/XO games. So there we are, I said it and I stand by it. Notice: WHEN DEVELOPING. It'll become clear in a second.

2. Will this change in the future? WIll devs discover some tricks to narrow the gap? Will stuff like XO cloud computing help? Hell if I know. Uhm, maybe? I know that devs -- well, most of them -- will do whatever they can do get you the best games possible. You're going to see a lot of multiplatform games this next gen, just as you've seen them in this gen, so it's in studios' best interest that there's no clear advantage in one version over the other.

3. Does it mean studios will cripple PS4 versions to match XO ones? Not really, do not underestimate the devs. Even if this happens, you will not know that and that's okay. You've never seen most games in their most powerful form anyway (when we work on them on our ninja dev PCs in 1080p 120fps with all the antialiasings and stuff turned on for shits and giggles). But most of the time devs have a target and they meet this target. If it's a multiplatform game, it's designed with this in mind from the start. So maybe it's not maxing out one console while going 100% on the other. Maybe it's 100% on both, but they take extra time for super-extra optimizations on the weaker hardware to make sure things look the same as on the more powerful platform. Etc. etc.

4. So what is that "one thing" I want to clarify, that some people may consider "damage control", but really is just an explanation. Someone mentioned Titanfall, which looks money and enjoys a great hype. Exactly. A great dev will make a great game no matter what's the hardware. Current gen CoDs looks great and it's 60 fps, on both platforms (well, and PC :). To most devs that is just impossible to achieve. And yet...

Think about it this way. X360 is faster than PS3. Not just easier to program on, it's faster overall (although PS is faster/better in SOME areas). And yet no exclusive on X360 looks like The Last of Us. Halo 4 looks great. Gears blew my mind in 2006. And still, the best looking AAA game of this generation belongs to the supposedly weaker platform.

So if you think that the war is over because PS4 is 50% faster TODAY, then you're delusional. This is far from over, and will probably never be over, at least not this upcoming gen.
