I guess most people already realized that this is a minification issue, where BenSkywalker argues from a magnification issue point-of-view.
My reference to the possibility of gray pixels obviously referred to the fact that mipmaps are box-filtered down, and the smallest mipmap for a checkerboard texture will be a 1x1 gray pixel.
As soon as you get to the point where you reach the level of minification where you require the smallest mipmap, the gray appearance is perfectly valid and expected behaviour.
And if you look at the progression of the texture from near to far, you see that the gray occurs at exactly the point where your textureixel ratio approaches 1. So there is no indication of cheating.
The irony of it all is that because of some of the things I wrote on my
developer blog, I was accused of being an Intel/nVidia fanboy... yet here I am defending AMD against some crackpot theories from nVidia fanboys.
Although I was actually defending the GTX465 in this thread because the reviewers didn't turn on certain optimizations that they did turn on for AMD. Make of it what you will, but I've always strived for being hard but fair and unbiased towards companies.
Scali, you can see that folks in here are trying to get the thread back on topic. Give them a hand, would you?
