also bin ich der nette user gewesen ^^

Hehe, dieser Chat beweist mal wieder wie wir von den Firmen beschissen und verarscht werden.

Hier ein Bild mit einer Antwort, das eigentlich alle Fragen zu dem Thema beantwortet:

bin jetzt auch drinnen! ist ein lustiger chat den mehr als auf dem Bild @23 ist noch nicht gekommen

 

[CSchnuffi5]

sind ja doch einige CBler on

Why are your trilinear optimizations different to what Nvidia is doing ?


Andy/Raja Raja: We won't comment on competitor's algorithms. Our focus is to retain full image quality while offering the best performance possible.

No-one is suggesting that our texture filtering algorithms produce a worse output than previous generations . In fact, if we took them out now the speed would be marginally less and we will receive complaints from users that our quality is lower . We did receive feedback from several folks who think that the X800 IQ is better than our 9800 series - it is always our goal to improve quality in newer hardware generations . To assist in this we have many additional quality controls in hardware in X800 series than on 9800

Our target is also to avoid any need to detect applications, and as such we have to try to be sure that our image quality remains high in all cases. To achieve this we spent a lot of effort developing algorithms to make the best use of our quality tuning options. This isn’t a performance enhancement applied to popular gaming benchmarks , it’s a performance boost – without image degradation – applied generically to every game that uses box-filtered mipmaps, which is most of them. This means, incidentally, that it’s working during the WHQL tests (unlike optimizations activated by application detection), which means that it has to meet the very stringent image quality requirements of those tests.

Ich logge alle Interessanten Antworten mal auf Bild mit, falls jemand am nicht reinkommt / nicht da ist:

[edit]
Bis jetzt klingen die Kommentare nicht als rausrederei seitens ATI.
Stattdessen bringen sie ne logische Begründung ihrer Handlungsweisen.
Das müsste beinahe jeden der zur Einsicht bereit ist, umstimmen.

also unter Chat stell icxh mir was anderes vor

man könnte ja zumindestens die fragen schon mal sehen
da war es als MF Chat Admin spannender

TheRock: will full trilinear filtering be allowed to be set in the drivers ?

Andy/Raja We try to keep the control panel as simple as possible (even as its complexity increases), and if the image quality is identical or better there doesn't seem to be a need to turn it off. However, if our users request otherwise and can demonstrate that it's worthwhile, we would consider adding an option to the control panel.

 

[MisterG]

singer: is this really trilinear filtering ?

Andy/Raja Yes, It's a linear function between the two mipmap levels based on the LOD.

 

[MisterG]

gs: When will ATI restore full trilinear so that review sites can actually rebench and retest your cards, since any previous review benchmarks is invalidated by this cheat/optimisation/whatever?

Andy/Raja We have never removed "full trilinear". We certainly do not believe that any benchmarks have been invalidated by our techniques. In all cases reviewed so far we believe that we have higher image quality than other implementations.

"gs" klingt ja verdächtig nach gamestar...so inkompetent wie die frage ist o_O

[MisterG]

Sphinx Question 1 : Is Ati cheating if Colored MipMaps are enabled and shows True FULL_TRI AF and Only Then. Like the Article in ComputerBase.de Descripe it as such one.

Andy/Raja Absolutely not. If it were the case that we were only performing full trilinear with coloured mipmaps then you might have a point, but this is emphatically not what we do. We take advantage of properties of texture maps for performance and IQ gains. In cases where we are not able to determine that the texture content is appropriate for these techniques we use legacy trilinear filtering. This includes cases such as dynamically uploaded texture maps where we avoid performing analysis so as not to cause any possible gameplay hitches.

 

[CSchnuffi5]

also wenn du schon jede Frage postest kannst du se eigentlich auch gleich übersetzen für unsere nicht Englisch sprechenden

 

[MisterG]

so schnell ghets auch nicht

 

[Snipermaik]

Fragt doch bitte mal warum eine gleichgetaktete R420 im Vergleich zu einer R360 trotz aller Hartwareseitigen Optimierungen in Colored-Mipmaps nur genau so schnell ist.
z.B.: "R360 vs. R420 "speciale" firstcoloredmip 1"

 

[CSchnuffi5]

hä? wo willstn das her haben?

eine R420 is bis zu Doppelt so schnell (XT)

 

[MisterG]

I think the whole community appreciates the time and the initiative for doing a chat about current filtering algorithm which certainly raised a few issues. Question: was the new filtering algorithm intentional and if you could tell us why werent review sites notified about it. Thanks

Andy/Raja We are constantly tuning our drivers and our hardware. Every new generation of hardware provides the driver with more programmability for features and modes that were hard-wired in the previous generation. We constantly strive to increase performance and quality with every new driver release. There are literally dozens and dozens of such optimizations that went into our drivers in the last year or so. Sometimes many such optimizations are not even communicated internally to marketing and PR teams for example. And many optimizations are very proprietary in nature and we cannot disclose publicly anyways.

is x800's hardware able to do "traditional" trilinear or is the new algorithm completely hardwired (not that I would mind :-) ??

Andy/Raja The X800 hardware is capable of all features of previous generations, and many more besides.

Habs mal editiert, war nen bissel unglücklich geschrieben.
Ich meine im Bezug auf "Colored-Mipmaps" also rein Trilinear.

 

[MisterG]

ich glaub des wars..ende
