The next two excerpts come from the official Radeon X800 Benchmark Guide supplied to the press.


ATI recommends tools that enable colored mip maps


ATI recommends turning off NVIDIA's trilinear
optimizations "to ensure a fair comparison"

What to make of all this?
Whatever the merits of ATI's adaptive trilinear filtering algorithm, ATI appears to have intentionally deceived members of the press, and by extension, the public, by claiming to use "full" trilinear filtering "all of the time" and recommending the use of colored mip map tools in order to verify this claim. Encouraging reviewers to make comparisons to NVIDIA products with NVIDIA's similar trilinear optimizations turned off compounded the offense. Any points ATI has scored on NVIDIA over the past couple of years as NVIDIA has been caught in driver "optimizations" and the like are, in my book, wiped out.
