'I said in another thread, ALL games use 100% of ANY consoles power. It's the way the code is used later in a consoles life that makes games look better.

Res 1 & PGR 3 for example used 100% of th power available, it's just now developers write much better code that utilizes the power better.

 

I have to disagree with you on this one.

That may have been true for the previous gen consoles... but the PS3 has what? 1 PPE and 7 SPEs and the 360 has 3 cores with 2 hardware threads each... or instruction pipelines... or whatever they are calling them.

 

So, if your game code makes use of the PS3's main PPE (it must), and 3 SPE... then you are using what? 100% of the computational potential of the cell? No.

You can measure average CPU usage this way.  The max (100%) being all the hardware threads never encountering a WAIT / IDLE / NOP (no operation) instruction.

Does it really mean anything at the end of the day? Probably not, but it IS definately possible that a game is not using 100% of a modern multi-hardware threaded CPU.

 

 

I see your point and it's very valid :) But it still boils down to developers code. They may not have had the knowledge before to usee all SPE's on PS3 or all 6 threads on 360, but they used 100% of what they knew how to do.

Even using all available threads, the next game code could still optimize the threads/SPE's better. So Square are definately talking BS. Naughty Dog said any dev stating % useage are talking bull, because code optimization gets better and better.

Remember Capcom saying Resi 4 wasnt at all possible on PS2. LOL. And look at Black last gen on PS2. :)
