WiiGeePeeYou (Hollywood) what IS it ?

No i have an actual benchmark showing that to be the case, 7.6 million polys with 8 lights, and 18million with 1 light, actual rendered polys for the GF4 Ti4200, which had more vertex optimizations than xbox1 had....


tell me that isnt as damn close to the xbox as youve ever seen in a benchmark? (btw the compared system is an athlon64 3000+ with a 6800GT @ 432//1140 =)

 

Yes but Factor5 may count it in other way, after all GC only do 12M, BTW thanks for the graph although remember that XB is a closed platform.

BTW anyone knoes here I find the first trailer for HS?

 

no, nintendo claims 6 - 12 million real world, factor 5 surpassed that at launch (15 - 18m for rogue leader). xbox is a closed platform true, but the Ti4200 had dedicated memory which was faster than the memory in the xbox1, it had vertex optimizations th xbox1 didnt. and it didnt texture in such an ass backwards way as to render any advantages of a closed box useless (apparently it grabs portions of a texture on a per poly basis? doing hundreds of thousands of fetches on high poly games?)

And regardless of how they count the polys, they are running 8 hardware lights, and it easily is more than 7.6 million polys, even at the worst case.....

 

Wasn't flipper more or less an 8 pipeline chip, so it's poly count isn't halved when doing 8 lights? (isn't Xbox's lighting higher quality anyway though?)

Plus, flipper was fixed function, I believe NV2A had a fixed function mode as well, not to mention it may have been possible to have the cpu aid in the calculations.

 

Did Rebel Strike use 8 lights? I know it used 8 textures, but I didn't think it used 8 lights.

 

you had the light from the environment which i might add also used light scattering, you had dozens of ties all shooting at you at any given time, each laser beam was a light source, so yes i believe it was pushing 8 lights...

 

Flipper was a 4 pipeline chip actually, and im not exactly sure how polycount is affected on cube, it doesnt seem to be at all given rebel strike.... as for the xbox, the self shadowing in rebel strike wouldve had be have used the vertex shaders on xbox, taking even more poly pushing power away from the machine....

Not to mention that any xbox game with per pixel lighting also had an abysmal polygon count and framerate (halo2, thief 3, splinter cell chaos theory, riddick anyone?) with per pixel lighting xbox cant even push 7 million polys/sec, that figure in that benchmark was lit per vertex, just like cube does its lighting in the majority of cases...

 

Hmm, I thought that Flipper may have been like the X1x00 series, where the elements of the 'traditional' pipeline seem largely decoupled from each other.
Only 4 pixel pipelines, but 8....I dunno what you would call them, ROPs?

 

Arent you talking about the TEV that read 8 textures?

 

Fox, it does not make sense to have more ROPs than fragments you can produce per clock.

btw, the classic rasterization pipeline has samplers, combiners and ROPs. but none of those has anything to do with vertex lighting - that's not in the rasterizer but in the TnL part of the rendition pipeline.

 

That's utter nonsense. Rebel Strike didn't push 21mill polygons/sec + 8 HW lights + 8 textures.
We've had this discussion before here and in a million other threads I am too lazy to dig up. Here's what the developers says

Factor5 is counting culled polygons, etc. in that number. 21mill p/s, 8 HW lights, 8 textures would even be beyond the theoretical limits of Flipper, go figure!

Well, how about 8 pipelines @ 243 Mhz (the rumoured clockspeed)?

 

The fabled light scattering is some minor TEV texture faking/trickery (at best; could also be totally pre-baked textures I suppose), completely separate from the hardware lights supported by the T&L unit.

I'm doubtful any polygon actually had 8 lights acting on it ALL AT ONCE. If even a majority of polys on-screen had, the scene would be bright as daylight. Except in tie fighter laser-green.

I'd say 1-4 lights on any one polygon at most. IE: directional light (the sun), possibly an ambient light, and 1-2 laser blasts. Most polys would only have 1-2 sources on it - the directional/ambient light(s), as the range of the laser blasts isn't super huge.

 

Well based on the benchmark i provided of a similar GPU, witth 5 - 8 effects and even 2 - 4 lights, Xbox still couldnt push enough polys in that situation to do rebel strike, as its throughput would be halved with the second pass required for more than 4 effects...

 

What's the point of this thread again? How GC graphics were better than XBs?

John Swinimer, Senior Public Relations Manager of Consumer Products, emphasized that the Wii architecture is capable of producing far better results than what we've witnessed thus far. "I think what you saw [on Wii] was just the tip of the iceberg of what the Hollywood chip can bring to the Nintendo Wii," he said.

Dunno if this is new to anyone. But perhaps the GPU is indeed more powerfull than expected, only devs got pre-alpha kits and thus pre-alpha kit graphics in time for E3?

 

The shader just has title now,

Planet GameCube: In a recent IGNinsider article, Greg Buchner revealed that Flipper can do some unique things because of the ways that the different texture layers can interact. Can you elaborate on this feature? Have you used it? Do you know if the effects it allows are reproducible on other architectures (at decent framerates)?

Julian Eggebrecht: He was probably referring to the TEV pipeline. Imagine it like an elaborate switchboard that makes the wildest combinations of textures and materials possible. The TEV pipeline combines up to 8 textures in up to 16 stages in one go. Each stage can apply a multitude of functions to the texture - obvious examples of what you do with the TEV stages would be bump-mapping or cel-shading. The TEV pipeline is completely under programmer control, so the more time you spend on writing elaborate shaders for it, the more effects you can achieve. We just used the obvious effects in Rogue Leader with the targeting computer and the volumetric fog variations being the most unusual usage of TEV. In a second generation game we’ll obviously focus on more complicated applications.

A hardware-accelerated recirculating programmable texture blender/shader arrangement circulates computed color and alpha data over multiple texture blending/shading cycles (stages) to provide multi-texturing and other effects. Up to sixteen independently programmable consecutive stages, forming a chain of blending operations, are supported for applying multiple textures to a single object in a single rendering pass.

For example the R420 architecture uses quad 64-bit memory controllers and a 16-stage pixel pipeline which can be scaled from 4 to 16 stages in steps of 4.

Could someone explain the differences in R420 16 stage pixel pipeline and Wii(GC) 16 stage Recircular Shader, or are they the same?

 

there's some misunderstanding here - a sm2 gpu does not have stages - that's a characteristic of the hardwired rasterizer, and stands for cascaded combiners.

r420 can do 16 samples per pass (i.e. per fragment shader routine). flipper can do 8 of the same in a pass. that is as direct parallel as you can do between those two.

 

I don't know how reliable it is but this supposed article from the new issue of Gameinformer seems to coincide with recent "developments".

It confirms support for normal mapping, bump mapping, HDR lighting among other things. It also talks about the dedicated physics hardware as well. On their own none of these articles seem to be much evidence of much but together they all seem to be painting a very similar picture.
