New dynamic branching demo

Re: It is, what it is.

Detail isn't the issue, not if they are part of the same mesh - in fact, this would serve BRiT's point more. The batch overhead issue is about the amount of cycles wasted just processing more individual objects - the smaller the object is the more overhead there is in processing those objects, so the issue occurs when you have lots of small "batches" of objects - you can end up wasting more time switching between the objects than you are processing them on the vertex shader.

 

Re: It is, what it is.

The thing people are forgetting is that this technique helps nVIDIA too. I think both sides are resorting too much to age calling.

 

I'd say it's mostly because you did it when posting the demo. It certainly didn't help your case that there were performance problems unrelated to the algorithm on nVidia cards, but that's hardly your fault (since you wouldn't have tested the demo on nVidia cards).

 

I cant see why ppl are flaming Humus for showing us his Dynanic branching demo . Methods like this is great for covering the gap between Sm2.0 and Sm3.0 . Not only will it benefit r300/420 owner but Nv30 owners to . Myself i believe there is potential in Sm3.0 . I was disappointed with the Farcry 1.2 benchmarks . Somehow i expected more from it . The question that is more relevant than that Sm3.0 is a useless feature is does the difference really matter with today Gfx boundaries .

Dave: I gotta comment you on that youre really patience . I would have banned certain ppl in her a long time ago . With these NvHeads and AtiHeads bashing together .

 

Got a link to some info?

When I was following the discussion before (haven't for a long time), the best anybody could come up with was 'shinier pipes'. Does it goes beyond this?

I found a firing squad article saying that pretty much everything is shader1.1 anyway (which would make sense given when the game was made and the platform it would have been developed on). Is that true?

On the surfcae it seems to me the differences just don't amount to much. I'm wondering if this whole farcry dx9 thing is a case of fanboys getting too carried away with themselves, desperate for some material to continue argueing about ati vs nvidia?

 

people are flaming because he is trivializing SM3.0 issues. yes
it might not give night and day difference but it will simplify development
and nice feature to have.

so what it can be emulated? anything on cpu/gpu can be emulated
if you have time and patience. but that's not core issue.

since he so pro ATI (not surprise since he's their employee). we need
balance point of view . BTW, I am not NVDIA employee but neural bystander. In fact I own Radeo 9800 Pro for fair disclosure.

Here's what I see
- SM3.0 is nice feature to have
- yes some of them can be emulated by SM2.0

this is what pro ATI factions are saying
- Sm3.0 is useless because nobody is using them
- there is no proof of performance improvement

now who has fair point of view?

wish Humus spend better utilizing his time working on improving ATI
product rather than disapproving competition's feature

 

Most ppl cant take a joke . This joke has seemed to hit you guys hard for showing this kind of behaviour . Humus must have hit a really weak spot . 19 pages and growing and mostly of it is fanboism . Shame on ye Greenies and redhats

 

I don't think anyone is saying that .

Some of sm 3.0 will speed things up. some will slow it down . So like any feature at times it may give a minimal loss and at times a small gain.

Most of us are saying its not very important to support as all the big name games for the next 2 years will be focusing on sm 2.0 as that has the largest installed base for the next two years at least (the radeons getting allmost all the top tier oem contracts will make that statment very true) . So while sm3.0 is nice and is no means a draw back it isn't much of a plus .

Esp if as farcry has shown the x800xt is faster than the 6800ultra even when its running sm3.0

Btw with all nvidia has done in the last 2 years its very hard to trust them on sm3.0 support.

 

Now now, most of us are yellow-duckies in waiting...

 

i have my neon 250 here . my kyro 2 is in my server .

 

I'm somewhat surprised that this thread hasn't been locked.......what else more is there to discuss

 

SM 3.0 is great.

SM 2.0 has yet to be fully utilised by the industry.

I see more games out using SM 1.x than anything.

 

The more SM2 support there is, the more opportunity for further optimizations using SM3 there will be. Of course, that doesn't mean I don't still think ATI's lack of SM3 support is highly disappointing. I still think they're holding games back.

 

Chalnoth, PS 2.0 hasn't even picked up yet and how long have cards supported it?

Since the R300 which has been nearly 2 years or something?

Ati or nVidia are not holding back the games industry. Coders code for the lowest common denominator and if they have time they knock in some extras like PS 2.0 or whatnot.

Look at how many people have low end cards these days.
Shit, my borther still has an NV20 and a P3 800MHz and all he's games run fine on them, even FarCry runs nice and smooth.

Until we see everyone upgrade their systems to something high end then things will continue to move slowly.

 

No one is saying that but you.

Bolded for emphasis. =P
