Title: Is This True?
Post by: MAKAVELIUK on March 26, 2002, 03:23:23 PM

i got this of gamefaqs boards


"every current title on the ps2 is using only using VU0, the main Vector Unit of the Emotion Engine. The second vector unit, VU1, is meant primarily for complex 3D calculations and has four times the horsepower over VU0. If you consider that one Vector Unit of the CPU is rendering the entirety of Devil may cry or Gran Turismo 3, the thought of how both games would look utilizing both becomes mind-numbing"

I personally don\'t know, but if it is true, then DAMNATION!!!

The PS2 is a machine with VERY, VERY MUCH potential. We\'ve only seen the beginning.

I doubt it.

And wasn\'t Jak and Daxter supposed to utilize both vector units?

No its not true.
VU0 and VU1 are at the same level of "power" or however you shall call it.

VU0: Available as a co-processor for CPU. More flexible calculation for dynamic data such as physics, animation.
VU1: Direct path to Graphics Synthesiser. Very fast transformation

There are several ways you can use the system. (1st generation games did not use it the most efficient way because of lack of documents on how the system worked)
Jak and Daxter is one of the first games to make use of the design.

As it says in "Tapping into the power of PS2!"

1st generation PS2
•Fighting small CPU cache,lack of VRAM
•Existing game with bigger textures
•Poly counts upped on models.
•Basic VU1 Directional lighting / Prelit
•Recompiled PC or PS1 code
•Minimal post processing
•Inefficient geometry

2nd generation PS2
•Working with the memory system
–Maximising DMA use
–Using efficient data representations
•Exploiting the architecture of micro programmable graphics pipeline
–Many different types of renderers
•Using GS fill rate
–Enhanced graphics effects

With that said, PS2 is far from maxed. According to PA2 (A tool that measures the performance of the system, it can take snapshots of the code while its processing ect.. Its not a hype tool like Watchdog said. The thing costs thousands of dollars and is made to HELP the programmers (1st, 2nd, 3rd parties), not hype up the games) GT3 only used 25% of PS2s potential.

Btw.. That dudes name wasnt Spacemonkey was it? :D

What fastson said.

GT3 is using both Vector units, the Core, and even the PSX board for sound, I believe.

Yeah, it uses them, but hasnt maxed them out.
