A little question about demo the getaway ps3 from E3...

[luke76]

I would be curious of knowing who of you believes that the demo of the getaway for ps3, shown to the e3, entire it is generated to video only from the cell and enough, without the aid of nobody gpu.In an Italian forum there's a boy that defines me a dreamer why cell, second he, will not be used in order to make rendering. That of thoughts of that one demo? True or false? Cell could generate to video that graphics without the aid of one gpu? Thanks for the answers that you will give to me.



P.s I ask excuse all for insufficient English but i'm italian i'm sorry

Benvenuto!

The Getaway demo was all done on Cell apparently, the chip calculated everything then sent the video to the place-holder GPU (not RSX at the time) just for rasterising.

But there seem to be lots of contrasting opinions over this.

According to Sony, it was all Cell.

 

[Titanio]

Whether it was done or not entirely on Cell as Sony claims, I'm gonna be optimistic and say it would be possible anyway. It seems like graphics works very well on Cell, so I'd be hesitant to bet against it. It's worth noting that a lot of the assets appeared to be PS2-era, despite how amazing it looked, which is perhaps relevant to how feasible it being rendered on Cell is.

I would find it strange that Nvidia would go on about HDR on RSX in the E3 confrence, then later have phil point it out in the G3 demo that was supposedly running entirely on Cell.

I just though that I was Cell and a place holder GPU (6800 maybe?) doing it, not Cell on its own.

It was Masa Chatani (SCEI CTO) who commented on it, you can draw your own conclusions:

For example we showed the demo that renders London City, it's not rendered in the GPU but the CELL does lighting and texture processing then outputs it to the frame buffer. Even without GPU, only CELL can create good enough 3D graphics.

You might think "oh, it's doing lighting and texturing 'only'" but that he goes on to say that Cell is outputting to the framebuffer kind of suggests it's also rasterising (and thus taking care of the whole process).

 

[_phil_]

How i understand it is that the cell is used for the whole management of traffic (car and pedestrian).Graphics are rendered on a GPU.

 

[Shifty Geezer]

IIRC Phil Harrison (?) said during the clip at E3 something like 'not only is this being rendered stunningly with HDR etc in realtime on Cell, but more importantly it's producing a real living world.' It was definitely implied all the rendering was on Cell, though subsequent discussion and high-level quotes and left a clear understanding of how it was rendered.

Thanks many to all how many for the answers (thanks for the welcome in Italian london-boy ). From what it seems to understand me the truth care the getaway after all these months, never is not jumped outside, like for the video of killzone. But however it seems that you are agrees on the fact that cell can work heavy on the graphics also alone and can generate it without the aid of one gpu right ? :smile:

I don't know if the cell could do it or not but I always doubted that demo because it had that same tear in the middle of the screen that you get with SLI gpus.

I dont have any experience with SLI, but you're not talking about simple v-sync tearing are you?

 

[pegisys]

sometimes the top half or the bottom half will be a few frames ahead and it looks like it splits

I think nvida fixed this with a driver update on the pc, but can you even get v-sync tearing with software rendering?

nobody of us know this, sorry
we have only guesses or interpretation of words, no facts

and for your english, 'è migliore del mio, tranquillo'

This isn't really something that is fixable with a driver update. If you do rendering that isn't synched to the vertical blank, it's going to tear. Just try filming a TV screen with a video camera for example and you'll see...

but can you even get v-sync tearing with software rendering?

Of course. If you swap buffers during the scanning phase there'll be a tear (if the two images differ, naturally), no matter if the graphics was rendered in software or hardware.

 

[Jabjabs]

not only is this being rendered stunningly with HDR etc in realtime on Cel

That's surprising, I though that was just Phil trying to drop the Cell word as much as possible, as PR people do, he was actually giving out information for once!

It's not that I don't rust him it just I find it very hard to beleave stuff that is said at E3 confences in general but that would be because of J Allard and Reggie who always look unhonest.

Eheheh many thanks Griffith , however your Italian is perfect

Some of "us" do know and that for a fact, but NDAs might force them not telling us, for now on at least.

Unless someone was directly involved with the production of the demo or knows someone who was. It's unlikely anyone on the board knows.
