2% is definatly bogus. I agree on the reason why you never want to hit 100%, but I mean really if your going to toss out numbers for what your game uses of a consoles strength do you really want to say something that low even it just makes the game sound bad

People still aren't happy I see.

When people that are first or second party (ala Insomniac or Naughty Dog), and they talk about the architecture and how much they've "tapped" into it, you guys get angry and say "First party devs always that their games can only be made on (insert system here)"

Now there's a 3rd party dev acknowledging that there IS potential, and that even they aren't close to it, but he's treated the same as the 1st and 2nd party guys. When will people just realize that Sony stuffed a lot of power in the PS3? Is it that impossible to grasp? If a computer had a quad core xtreme processor with 2 768MB video cards in there, would you guys say that it's not powerful, just because someone who MAKES GAMES FOR IT says that it is?

And for the record:

For people saying that 2% is too low....maybe. But don't toss in 20%, however, Uncharted is only pushing 30%....and just look at that game

why do they bother making these absurd arbitrary percentage of power, it doesn't make any sense
unless they've just got the machine waiting for some stupid number of cycles, or have loads of unused ram they are taking advantage of every scrap of the machines resources
they could say that they believe the machine could be used a whole lot more efficiently, which would make sense, but as it stands they are using 100% of the machines power

@Quartz

Exactly what i was thinking how can u determine what percentile of so called power is being implemented, without a point of reference. How much is 100%? Any developer that attempts to quantify what is essentially thoeretical power is blabbering nonsense.

the demo for turning point sucked balls. I'm sorry to sound so juvenile but it was terrible. I thought it could be amazing, with its story and all sounding cool, but the demo sucked.

All of these percentages are bullshit. Stop giving them out, and stop eating them up.

From a programmer's perspective, I can see two ways of measuring such a percentage:

1- You profile your program, check how much CPU time you're consuming (i.e. time minus idling time - aka System Idle Process under Windows), divide the result by the time the program ran for, and you have a percentage.
2- You pull a number out of your ass.

Now, I very much doubt that they used method 1 here and got a 2% result. If that was the case, it would mean one of two things:

a- Their game is so basic that it barely uses the PS3's CPU at all. Even if they only used the PPE, and none of the Cell's SPEs, that alone would make the percentage much higher than 2% (there are only 6 SPEs after all).
b- They optimized the game like Michael Abrash on steroids would.

I doubt either of these two things happened. The former is not likely because the game doesn't look basic, and the latter is very unlikely because they don't have Michael Abrash on their team, and it would be a waste of time to optimize their code so much.

Conclusion:

They probably used method 2 (pulling a number out of their asses).

He says 30% of the CELL.  They make no mention of how much of the GPU's resources they use.  The PS3 isn't JUST the Cell, and despite the impression he gives, the GPU is used for final rendering duty.  The Cell just helps the GPU by processing lighting and vertex information before it's sent to the GPU(This frees up more of the GPU's resources to use for other rendering duties).  The GPU handles the pixel shading and the bulk of the actual rendering.

The 360's GPU is more powerfull than the PS3's so devs have to start using the SPU's to offload certain tasks.  The first/second party devs seem to have gotten that down.  3rd parties are finaly starting to get it too.

It is very interesting to see all of these numbers coming out that developers are claiming that their games are running at. I mean, remember when EA said that Def Jam Icon used 100% of the console's power? I don't think it's really possible to harness 100% of any consoles power right now (Wii aside, no offense meant)
