Isn\'t there anyway you could transfer the info from powerpoint.. so that we can simply read it here?  Or is there too many?

No :(

You must have PowerPoint to be able to view all the slides including the pics with the PA2.

fastson, what\'s the date of this lecture?

I only read the text, which was interesting enough for me without the graphs. While it confirms the PS2 has a great deal of potential left to be exploited, it also re-establishes the extreme difficulty in doing so and suggests getting 80 or 90% efficiency (my estimate) within the next few years may be out of reach for even the most talented developers. A lot depends on when the talk was given.

Not that it matters much, I\'m satisfied with the higher end results to date. Though I would feel better if smaller devs had access to, say a 50% potential, without too much hair pulling/trial and error effort. The aid of C compilers seems very limited at this stage. Again, if this lecture was given a year ago there maybe room to be more optimistic.

Heretic: Im not sure.. But I think its pretty new.
As he said "the PA has been avalible since April" so its from this year.

Anyways I hope the PA2 can make the same huge difference on PS2 as it did on the PSX.
Remember GT1? :)

If I remember right, a PA for PS2 was available long before J&D was ever released, though Naughty Dog never used it. The speaker does mention the one being used for the slides is an updated version. So I dunno. It was just this spring Vector C for PS2 became available, right?

You know what though? Screens of much improved PS2 graphics have been popping up lately. SH3, the F1 racer... Vice City seems to be a huge leap from GTA3...

Yeah, the PS2 still be cookin\' in my book

He says in the article (or whatever you want to call it) that its been avalible since April, but only at Sony HQ.
So if you wanted to use it you would have to go to Sony to test your code.

Im not sure about it being avalible before J&Ds release..

I remember the TimeSplitters 2 developers saying that they had been using the PA2 for a few months to optimize.

Im not sure when VectorC was released but now it seems they have gone belly up :(

Exacly, I was blown away when I saw the new SH3 screens and that new ZOE2 video.
I cant wait to see what the code gods at PolyPony can cook up for GT4, or what Naughty Dog can do with J&D2 (prays for a sequel) ..

The guy in the paper said he was very impressed by their skills.. :)

Here he\'s talking about J&D (cuz to my knowledge J&D is the only game crunching this many polygons!)

Ok, so just to finish up I’ll show you again the scan from the very first slide. This is a title which achieves a lot of stuff I’ve talked about today. Notably, for most of the time it’s drawing stuff it’s churning out 10 to 20 million polys. That’s no a random benchmark, that’s physically what the GS starts drawing and like I said during the PA description, it doesn’t count zero-area stuff.
Also, the CPU usage is up at about 50% or more, which is more than double what an average title might see, and better than most good titles by a decent margin. It’s also getting dual-issue for about 80% of the time during the critical processing phases (about half a frames worth).
So good performance is possible, and not only that, but this title was written without the aid of the PA, only using the built in performance counters and a lot of skill. It’s also not perfect and I fully expect to see this developers next title beating this performance on every level. Hopefully you guys can do the same.

That\'s a shocker  :surprised

Perhaps if this PA paper/lecture is recent it was the kiss of death for VectorC. If it was any good I can\'t see Sony letting Codeplay just go away  :confused:

Thanks for passing along all the info fast , as usual :cool:

Yeah, it would be pretty cool if Sony could pick this VectorC up.

All to help the developers get the sweet juices out of PS2 ;)

Wow thanks alot for this great info Fast. I was away for 2 weeks (in Malta), but am back again and look forward to some serious posting. I\'ll make sure to comment on the PowerPoint presentation once I\'ve read it.

Ahh, just saw it\'s downloaded... better check it out then. :)

Perhaps they could make the game look as good in 2 player as it does in 1 player. :mad:

Then again, people play GT for the single player, not the multiplayer :)

J&D is only pushing 10 million pps (with information).  GT3 is pushing up to 20 million.

In fact lots of games on PS2 are using over 10+mpps
