Although I know U2 will be absolutely stunning, I hope it isn't going to max out the PS3.
As Squilliam (i think) once said anyone can max out just about any system by forcing it into infinate loops.
more efficent code will also lessen the risk of maxing out the thermal threshold of the PS3 which could lead to component or fan burn-out on some PS3's. This would be unwise.
I hope that they just mean that it will be spread out on all available SPU's instead of maxing out every SPU available.
tighter coding FTW!
If this post sounds odd it's because I'm currently knackered. deal with it. lol
