Impressive 1 liners...ever considered a career in the SDF ? we have good dental cover.

This gen sony is shooting their own foot enough without any help... I just help out when I´m bored... KZ2 does indeed look very impressive... but my eyes tell me that... not my math or hardware knowledge... masturbating to numbers just puzzles me...

If they said they only used 60% why? Why wouldn't they use 100%? That's foolishness.

Why doesn't pacman use 100% CPU time on your quad core PC?

The PS3 includes many new state of the art tech, especially the Cell provides and needs radically different and more modern approaches. Writing game engines take time to develop. It's a bit like asking why wasn't Rome as big as it is today when people just started building the city. Understand?

SPUs are like hidden achievements... the reson only 60% are used is only that many have been found... its like a tresure hunt inside the PS3 hardware... the dev team to find most PSUs can make the best game... its a fun concept...

I don't have that kind of problem with Firefox 3. I have 76 tabs open right now and some of them are VGC tabs. At 76 tabs, Firefox takes 212 Megabytes on my computer. Well, CPU is high, but right now I'm on Vista and CPU always runs high for me on Vista, but most things I do goes smooth.

Killzone 2 looks like a promising game. I like developers that shows what consoles are capable of!

There's that and the (IMO) bigger issue which is probably non-CPU bottlenecks that they may have hit.

For example, if there were no other bottlenecks, it should have been fairly easy to implement split-screen, right? 60% means little more than half of the CPU cycles are being used, while split-screen shouldn't nearly double the load on the CPU.

Yet, split-screen wasn't implemented, which leads me to believe the game is not limited by the CPU but by something else (memory? GPU? who knows...).

Load balancing is probably the reason. They probably don't have a method of assigning work to different SPUs as they become overloaded, I suspect that work must be assigned by the developers to a specific SPU from what I have gathered from developers working on the PS3.

Because it mixes everything up, it makes predicting the workload difficult if you've got two different people looking and fighting in two different directions.

@Squilliam: So in other words, you're saying that the SPU performance was the bottleneck. That could well be the case too. That's another problem with making game engines, you have a limited time to calculate a frame or slowdowns will ensue.

@ NJ5 and Squilliam

I really don't understand why you continue to ignore the actual devs, this is more than clear enough:

PSU: "It's incredible to see huge levels and see the deferred rendering and note that on all the SPU’s, even on the heaviest load were coming up to about 60%," Haynes said. "They weren't coming close to maxing out. .They had about 40% of space before they started tripping or saw slow down on some of the processes."

Why oh why ignore them.....
