Wow so double performance is confirmed? Wow that is very good for the Xbox One.

MS said double? Maybe you should go read the OP.

No but they said Perfect Dark Zero to Halo 4. Right? Surely, that's double.

This horsesh*t is the same crap that I heard back in the day when Sony tried to spread cowdung over the fact the cell was a fuc*ed up architecture. The GPU in the One is garbage and no matter how much they pump up the graphics the FPS will chug like a Quake 4 multiplayer battle. Moronsoft better do less of this sh*t and get the other tech turd, Nintendo together for a powwow and have Mario's bit*h become a publisher on the piece of crap Beta machine looking xbox gone!

Pretty pathetic how gullible they think people are. Sad thing is some will actually believe it.

This crap seems like the same crap I heard back in 06' when Sony was trying to explain off the stupid cell processor crap. The xbox one's GPU is total garbage and they better do less of trying to pump up software and more trying to sway Nintendo into becoming it's main publisher! All that this is going to do is make sure all the ports run at 1080p..All you slappies better get ready for some Quake 4 style frame rate! 

360 game to 360 game can be double, Xbox One can't? I don't think either are but...

Interesting.

What? What I'm saying is not negative towards the Xbox one. I am saying that we will see a boost and that is a good thing. What I wonder is, if the boost will be immediately noticeable in games, or if we will have to wait 2-3 years to actually notice a big difference.

I think you misunderstood me. No worries.

Are you serious? What was all that "insider" BS before then? You're agreeing with me now?

Of course it will tak time. DX12 has just been announced!

Double the API performance doesn't mean double the system performance.

Consoles have a multitude of API's for which they can use, depending on how complex the game is, higher level API's (Like Direct X) generally are slower, however they are also very easy to use and develop for.
Lower level API's however you have to get a little more dirty with, but does bring with it some good performance benefits.
Then you have the very rare (Especially now-a-days, with a couple of exceptions.) where it's actually written to the metal, skipping the API and other software stacks completely.

Basically, from Microsoft's press releases, information and outlines of the improvements Direct X 12 is going to bring, the main goal is to take some of the low-level API's advantages and abstract it in a way to keep developers lives easy, this is the goal for not only the Xbox One but the PC version of the API.

The kinds of improvements should be a little more severe than what Mantle gave us, AMD's focus was mostly on draw cell improvements with that API, but it gives you some idea of the direction that Microsoft is heading down.

The part I am looking forward to is now that Microsoft is fealing the pressure from the Playstation and AMD's Mantle and a reinvigorated OpenGL, they are no longer sitting on their laurels slowly iterating in the PC space, which pleases me greatly.
