Sony Secret Weapon revealed...? (Great Article)
The latest issue of Edge Magazine unveiled Sony's secret weapon, with interview from developers regarding the "Performance Analyser."

------------------------------
Sony's 'Performance Analyser' was first unveiled on the PSOne when Yamauchi let slip the Gran Turismo had been developed using it.
Now, finally, the performance analyzer has been unveiled for the PS2 -a piece of machinery which can measure just how much of each processor is being used. The performance anaylzer can let developers understand how they can optimize their games and this can lead to a massive increase in speed.
From EDGE: "Simply described, the Performance Analyzer gives developers a window into the inner working of games running on the PS2 hardware. There are three probes, one which deals with the emotion engine, and two on the graphics synthesizer chip. The probes tag all the inputs and outputs into those pieces of silicon."
Free Radical (developers of Timesplitters 2, Goldeneye and ex-members of RARE) were interviewed by EDGE about the PS2 version (the lead version) and they had this to say:
"So far, we've doubled our polygon throughput in Timesplitters2, but there's still some way to go" reckons Free Radical Design's Steve Ellis. "We're probably using under 70% of the PS2's power. It's a complex machine and it's not always obvious where the bottlenecks are. It's early days at the moment, and developers still have to go to Sony's office to use the Performance Analyzer, which is a little restrictive"
"On Playstation2, we know it's possible to get over 20 million polys a second out of the machine." said Attention to Details lead programmer, Tim Swan.
Also, Jak & Daxter did not use the Performance Analyzer at all for development as it was not available at the time.
Fred Williams from BLITZ games says "There's a vast amount of scope for some giant leaps performance-wise on the Playstation2. On the more straightforward next-gen hardware (xbox, gc), you'll see less of a polygon performance jump..."
Soon the Performance Analyzer will be included as standard as part of the new dev-kit, and I can see it making a massive improvement on games as it will be easier for developers to see out to optimise their games. It made massive improvements on the PSOne, and I can see the PS2 going in a similar direction.
PROJECT GOTHAM RACING Roger Perkins, senoir programmer said "I'd hope to get another 10-20 percent out of the console [xbox]" Bearing in mind GT3 only using 25% of the PS2's power, we could be looking at a 70-75% improvement over GT3 - which looks almost if not AS good as Project Gotham.
Finally, Free Radical had this to say about Microsoft's DirectX-based XBOX:
"The best thing Microsoft could do to help developers acheieve maximum performance from XBOX is to allow them to ditch DirectX", he fumes. "Like Sony, Microsoft should provide full low-level details of the hardware and let the developers create their own libraries which are optimised for the game being developed."
