ATI cannot make working video drivers

[audiofreak]

I don't need glasses and the colored area is the only area you should be concerned with. This same AF test has been used for years on most tech sites when reviewing video cards and never once that I can recall has a reviewer ever mentioned being concerned with the gray area. The colored circle is the benchmark sample. If you can find information from a credible tech site that says the gray area is important as well, please post it. The colored area is what determines the quality of the filter.

"GRAY AREA" IS THE TEXTURE that the filter is being applied to!

There should be a mandatory intelligence test before granting people Internet access, and it should require an IQ of at least 120. Forums would then be a much better place without all those two-digit-IQ trolls.

EDIT:

I got an advice via PM to stay calm -- I appreciate it, I have toned my post down a bit, and I am doing my best not to lose temper, but it is really hard to tolerate people who know nothing about the subject yet feel invited to comment with authority.

Split screen render of anisotropic filtering as a final proof:

Scale 0.5x (banding even more obvious):

For uninitiated, left side is rendered by ATI HD 5870, right side is how it should look (rendered by reference rasterizer).

Here is the program if you want to test it yourself:

This epic anisotropic filtering fail is present since HD 5xxx series launch, that is obvious from initial filter test screenshots which you can find in numerous reviews.

If it was software problem ATI would fix it silently, and I would not be able to get the same result with the latest ATI drivers.

Think about it, if ATI could not fix this in software for a whole year, then it must be a hardware limitation. What is extremely disappointing for me is that it wasn't present in HD 4xxx series.
