Developers Thoughts on PS 3.0

Saw This Link to Developers thoughts on PS 3.0 at Gamers Depot.

To all those trying to downplay the importance of ps3.0; you might wanna check this out.

I liked this statement as relevant to many of the questions and debates I've read over the past couple days regarding the need for PS 3.0 feature:

GD: As a gamer, would it be more important for you to buy a video card with the utmost in performance and supported 24bit precision and PS2.0 or one slightly behind in performance but had PS3.0 and 32bit precision support?

Mark: I think today it's more of a personal preference, seeing as only a handful of games currently support either PS2.0 or PS3.0. But by the end of this year there will be enough games using PS2.0-PS3.0 for people to decide which card better meets their needs. I would personally go for the card with a higher feature set, because then it will have a longer life span. Besides, if card X runs Q3 at 170fps and card Y runs Q3 at 180fps, who cares? As long as I get at least 60fps, I'd rather have prettier graphics.


And also:
GD: How far away do you think we are until we see PS3.0 and 32bit Precision support become relevant as a "must have" feature in graphics cards?

Mark: Well as most developers will agree, commercially successful software has to tread a fine line between support of new high-end features, and satisfying the most common installed base. Once both major IHVs have their PS3.0 high-precision cards on the market, the very next generation of software will begin to take advantage of these features. What will really clinch it is the 'killer app' that requires PS3.0 in order to look its best. If Doom3 adds PS3.0 support then I'll bet that that's enough for gamers to want to buy into the new technology in big numbers

Cool, doom 3 with ps3.0 support. (*drool*)

And for the Ati Fans:

GD: As a gamer, would it be more important for you to buy a video card with the utmost in performance and supported 24bit precision and PS2.0 or one slightly behind in performance but had PS3.0 and 32bit precision support?

Bart: Highest performance wins.



It will be really interesting to see if the ATI Card is actually faster than nvidia, if so the case could be made....either way? LOL
 
Now, which of those developers are associated with nVidia's TWIMTBP campaign? And which with ATi's GITG marketing? The answers are interesting, though not paticularly surprising to the cynical amoung us.
 
According to most of the people on Beyond3D, there is almost no effects that you can do with SM3.0 that you cannot do with 2.x which ATI will support. The only real difference is that you will need more instructions to do it in 2.x.

Less instructions = good. If ATI doesn't have it in R420 then they made a mistake in judgement.

That is about PS 3.0 in VS 3.0 there are some new stuff but then the R420 is supposed to support VS 3.0 not that I can say I am sure of that...

I have heard that as well. I have also heard that the only thing the R420 does not support is dynamic branching. But we will see.

That and of course 32-bit precision...
 
I don't think there is any question ATI's capabilities will be somewhere between 2.0 and a full 3.0

Its just a matter of where the differences lie. It sounds like ATi decided to not go full spec on the maximum number of instructions.

This was probably a conscious decision, similar to Windows64 and the decision to not go over an addressable 16GB of RAM. Even though a true-64 bit operating system can address terabytes, they deemed it not necessary in the foreseeable future to go beyond it (99.99 percent of software would not use it unless specifically coded to be "bloaty")

Using the maximum number of pixel and vertex instructions in 2.0 would be considered to be very bloated code given the capabilities of todays CPU's.
