An einer Stelle haben wir diesselbe Meinung. Es ist Betrug. Nur ist es nicht gewährleistet, ob NV ebenfalls cheatet. Niemand weiss genau, was sache ist. Hier mal ein Kommentar von ATI:The_Jackal schrieb:Ich sehe es wie Graka0815. Es ist Betrug am Kunden und unlauterer Wettbewerb. Wenn man sich nichtmals mehr an Benchmarks orientieren kann, dann hat man keinen Anhaltspunkt mehr, wie gut oder schnell die Karte ist.
Kein Wunder, dass die X800 Karten schneller sind als die Geforce 6800. Die Qualy wurde ja gemindert. Schade ATI.

recently.
The objective of trilinear filtering is to make transitions between mipmap
levels as near to invisible as possible. As long as this is achieved, there
is no "right" or "wrong" way to implement the filtering.
We have added intelligence to our filtering algorithm to increase
performance without affecting image quality. As some people have
discovered, it is possible to show differences between our filtering
implementations for the RADEON 9800XT and RADEON X800. However, these
differences can only be seen by subtracting before and after screenshots and
amplifying the result. No-one has claimed that the differences make one
implementation "better" than another.
Our algorithm for image analysis-based texture filtering techniques is
patent-pending. It works by determining how different one mipmap level is
from the next and then applying the appropriate level of filtering. It only
applies this optimization to the typical case - specifically, where the
mipmaps are generated using box filtering. Atypical situations, where each
mipmap could differ significantly from the previous level, receive no
optimizations. This includes extreme cases such as colored mipmap levels,
which is why tests based on color mipmap levels show different results.
Just to be explicit: there is no application detection going on; this just
illustrates the sophistication of the algorithm.
We encourage users to experiment with moving the texture preference slider
from "Quality" towards "Performance" - you will see huge performance gains
with no effect on image quality until the very end, and even then, the
effect is hardly noticeable. We are confident that we give gamers the best
image quality at every performance level.
Microsoft does set some standards for texture filtering and the company's
WHQL process includes extensive image quality tests for trilinear filtering
and mipmapping. CATALYST passes all these tests - and without application
detection, which could be used if you wanted to get a lower-quality
algorithm go undetected through the tests.
Finally, ATI takes image quality extremely seriously and we are confident
that we set the bar for the whole industry. We don't undertake changes to
our filtering algorithms lightly, and perform considerable on-line and
off-line image analysis before implementing changes. This algorithm has
been in public use for over a year in our RADEON 9600 series products, and
we have not received any adverse comments on image quality in that time. If
anyone does find any quality degradation as a result of this algorithm, they
are invited to report it to ATI. If there is a problem, we will fix it.
