"PS3 1000 times more powerful than PS2"

[Bobs_Hardware]

Sorry, thinking about it, my information is way off .

A theorhetical limit, of probably about 20MB\'s @ 60fps

Well, the PS2 has a 1.2GB/s bus from the main ram to GS, correct?

If the PS2 were sending 1.2GB/s of textures (unrealistic) @60fps = about 20MB

Let\'s say it was sending a more realistic figure of 800mb/s, it would be about 13.4MB

At 30fps it would be double that, etc.

Or am I just completely on the wrong track here?  

SEVEN.... I WANT TO LEARN!!

no no, you\'re on the right track. I knew the ~20 MB figure, just not how you got to 16.8 MB that\'s all.

I did read that article with Naughty Dog pushing 40 MB of textures per frame, but right now, I can\'t be sure how they managed that. The only thing that would make sense, if is the GS recognises CLUT and thus the textures are being sent "compressed". Or, what might be even more realistic to assume is that one image is made out of, lets say, 2 layers. As one bitmap, it would take up 192 KB, but if you cut it in 2 layers where 1st layer = 12 KB and the 2nd layer = 8 KB You\'d be saving an incredible amount of data. Of course to get that 192 KB texture, you would have to blend the two layers accoardingly. The effective data being streamed though would only equal 20 KB though...

make sense? If not, tell me and I\'ll make you an example with actual images.

Yah, makes sense.

I guess that would also work with the fact that I believe in the article with ND, they stated they were achieving the "equivilent" (IIRC) of 40+ MB\'s.  

In your example, they are still getting the \'equivilent\' of the 192KB texture, at only 20KB\'s.

I still think you should e-mail them, though.  

yeah, I guess I should... On second thought, I am pretty sure that\'s how they did it. Quite an achievement come to think of it.. that amazing amount of polygons and then the textures... :eek:

It would be interesting to know how much those 40 MB of textures would be in real numbers...

I\'m more interested in how the hell those textures in Silent Hill 3 are so frickin\' amazing.  I\'d love to see Konami\'s figures.  But they don\'t seem to be as promotional with their efforts as Naughty Dog were.

Can you picture how good MGS3 is going to look :eek: Konami are doing something right.

Or hell, just J&D 2 would be nice

Yeah... and even if MGS3 doesn\'t have those textures, simply because of the talent and artwork, it will look amazing - that I am sure of.

Speaking of WOW-effect, I still think Z.O.E2 is the most amazing thing I\'ve seen. Sure, it doesn\'t have those amazing textures, but wow, did you see the particle effects? :eek: :eek:

I prefer Silent Hill 3.  Particularly the videos which involved the old man.  Everything on his face is so detailed, from his stubble, to wrinkles, his hat.  In the video where they were driving in the car, and they cut to him just as a car goes past and he turns his head.  The dynamic lighting altering, and reflecting off the environment, and self-shadowing causing his NOSE to cast a shadow on his CHEEK. Aww *drool*

I swear, if it\'s not FMV, it\'s what Sony actually promised with the whole Toy Story graphics hype.

(If it is FMV though, I\'ll feel pretty stupid )

On a side note, we\'ve hijacked this thread! *high-fives*

well, I guess I\'m just still very sceptical about SH3... Just to say though, despite the amazing quality of the video (the car scene), it\'s evident to me at least that those are in-game sequences. I think FMV would be a tad bit more impressive...

Also, Konami also said that their not using any FMV this time \'round..

Last time I checked...the project is already done and should be prepared to ship possibly with the PS3 in early 2004...and it has well over a teraflop of computing power.

You\'re thinking of a fake article that was circulating some time ago, Evisc.  

The designs of Cell are finished, I don\'t believe they have a working prototype yet.

hum, but the 1 TFLOP figure should be quite accurate. IBM released possible specs for the CELL. I think one individual cell can perform 1 GFLOP, but the processor itself has multible cores (or cells).

On a further note, I just found out that the PS2 can deal with JPEG compressions. Because the IPU (Image Processing Unit) has to deal with them on the fly though, it\'s not used that much as of yet, as it\'s pretty hard to keep it efficiant. It is possible though and you may be looking at a 10:1 compression rate.

So that gives us 3 possibilities:

4bit CLUT, 8 bit CLUT and JPEG.

15:1 compression at medium quality, but only for the main memory.

I remember hearing a developer saying that he could send 5-8 MBs of texture data to the the GS per frame@60FPS, which is ok but pretty low for a system nowdays if you\'re not using any form of TC. If they used a little program to decompress the textures on the GS that would give a serious boost in texture quality in PS2 games (and solve most IQ related issues at the same time IMHO).

Those numbers Naughty Dog gave (45-60MBs/frame) are pretty close to what you could get on the PS2 if you were using 6:1 TC.


Anyway, I\'ve always had the impression that PS2\'s texture capabilities have been heavily underused at times, but it doesn\'t seem to be that easy to solve.


PS: All this threads about the PS3 all over the net are making no sense (no offense, Adan ), which supports my theory that 90% of the hype comes directly from gamers.

Everyone wave to Mister. Hype . He likes making door to door stops for Sony!

Oh...sorry about that. I\'m confusng myself...:shy:
