It\'s important to have a very good 3D engine in order to create great special effects - if we want dust, we can just make dust, if we want rain or snow effects, it can be done very easily. We\'re not limited. I think we\'re using between 85 and 90 per cent of PlayStation 2\'s capabilities, which I think is similar to Gran Turismo 3, so there is still scope for improvement.



What a prick.. hell, everyone knows that GT3 uses about 25% of the PS2\'s Power.

Huh...where does this "common knowledge" come from. I do trush a developer more than some hearsay.?!

It ain\'t a rumour dude, you just gotta know what your talking about.

GT3 pushes about 8 million polygons TOPS, thats only with some effects.

PS2 can theoretically do around 60 Million without effects, 20-30 million with.

From Kaz (creator of GT series). He said about 25%.

85%? impossible... GT3 began to be made few months after the launch of the system... how the hell is going the game to use 85%? No way...

Wait a minute. He might be right. If you program the game to use the console\'s resources inefficiently, then it could be a resource hogger.

If anyone has played Dynasty Warriors2 and 3, it has poor draw distance, slow downs, disappearing enemies right before your eyes coz of the amount of enemies on screen.....if it\'s not using the console\'s resources properly, then yes, it is using that much power. Kinda like driving on 2nd gear at full throttle but never upshift, it will use up all the car\'s horse power.

a fair comment Gman, but it still stands that GT3 can be done using a mere 25% of the machine if it was optimized.

The devs of V-Rally 3 surely have the Performance Analyser 2 at their disposal so they will get
great usage out of the PS2\'s archetecture. if there using around 85% of the PS2 whilst using the PA2
then we should be in for a treat. I\'m just hoping that they get the handling right.

I\'m no programmer. So here\'s my question : does the PA show how efficient their programming is?

We worked closely with Sony to make sure that we used the maximum capabilities of PlayStation 2. By that we mean we went to their offices and used their tool (the Performance Analyser) to look at our code and see exactly where we were using the PS2\'s power properly and where we were not. This has helped us optimise the 3D engine and now the draw distance is very far...

Probably not. The analyzer measures the resources used by the coding. Not how the coding could be changed to acheive better results from using less resources. Like I said, I\'m no programmer. I did some programming for a couple of years in college but that was years ago.

Gman, they use the PA2 to see what the code is doing. remember, the ps2 has more than 1 processor.

The PA can show the developer what each processor is doing. thus, if there\'s a processor under 100% load and
one of the others is only at 20% load, they can change the code to use different chips, thus offloading code onto another chip.

They can resolve bottlenecks once they know how to squeeze more out of the hardware and make it communicate
better between the EM / VU0 / VU1 and all the other little bits that
go into the PS2.

Memory management can also be bettered and any code streaming bottlenecks can be seen straight away
and the code modified to change any bad bottlenecks that may have been implimented in the game engine by mistake.

Or am i just talking total crap.. i believe 80% of the above to be correct, but i\'m no expert on the issue.

Plainly put...

They can see exactly what the machine is doing and they can modify their code to run more efficient.
