Sorry if this has already been posted.

I'm sure most remember the Driver Heaven article calling Nvidia's image quality into question: http://www.driverheaven.net/articles/driverIQ/

It seems they have finally gotten a response: http://www.driverheaven.net/showthread.php?s=&threadid=44752

It even includes a quote from Microsoft, "The DX9 reference rasterizer does not produce an ideal result for level-of-detail computation for isotropic filtering, the algorithm used in NV40 produces a higher quality result. Remember, our API is constantly evolving as is graphics hardware, we will continue to improve all aspects of our API including the reference rasterizer."

LOL just read some of the comments after the first post, apparently NV is "hardware cheating" now. :rolleyes:

There really are a lot of fanboys on that forum.

quote

"This is the type of IQ issue you are likely to see across all applications due to the NV40 rendering method. How significant or insignificant this is should be left up to each individual. You should also take into account the impact of these changes will vasy from game to game."

Still needs some looking into, but there are new drivers out now, so we shall see what happens.

I still find it funny that in the original article, the reference image was different from ATi and nvidia.

So what does Microsoft render their reference images on?

The Refrence image means its done by software, eg a bunch of algorhytms that run in the cpu. It takes a LONG time too heh.

so according to microsoft the NV40 is generating a better image?

Microsoft says that NV40's algorith is higher quality than their reference rasterizer, yes.

I haven't read the full quote ... but from what was quoted above ....

It also means that Microsoft sacrificed "level-of-detail computation" for performance as that is the only reason that could explain the quality degradation. As a consequence any image generated by DX9 rasterizer is not a true "reference" image as it would include performance enhancements that the hardware version might not have. That is so damn stupid of Microsoft.

I'd just like to add that some guy from Driver Heaven posting a screenshot of a bunch of lines doesn't mean a damn thing to me. So far they have not produced one screenshot that doesn't contain mip coloring or some kind of funky crap we wouldn't see in-game.

Driver Heaven: Please post some real shots, or apologise for trying to start a with hunt, kthx? If Microsoft says the NV40 is higher quality, I am inclined to side with them, not some dude who just learned how to turn on colored mip maps in 3dmark. :retard:

From my first series of postings that got me in trouble at DriverHeaven for posting something different than the staff's opinion:

4/23/04

Perhaps DriverHeaven has stumbled upon next-gen filtering in action.

4/23/04

the way i see it from conversations today with Nvidia, your theory is quite suspect. Especially as the PR ive talked to dont seem to be aware of any of this LOL.

Futuremark:
The explanation for the rendering differences is GeForce 6800's new isotropic filtering algorithm: It differs from that of the reference rasterizer...

Microsoft:
The DX9 reference rasterizer does not produce an ideal result for level-of-detail computation for isotropic filtering, the algorithm used in NV40 produces a higher quality result. Remember, our API is constantly evolving as is graphics hardware, we will continue to improve all aspects of our API including the reference rasterizer.
