When it comes to games, if people don't notice IQ differences, they don't care. For most people, it is the final image that matters. (Synthetic benchmarks, they may care depending on what exactly the benchmarks are testing, but that's another story/thread).

The colorized thing, just highlights the exact filtering technique, in respect to being trilinear, nothing more. (As shown, in UT2K3 anisotropic filtering isn't highlighted by the colored bands for either card, so using the color band thing to judge overall IQ is flawed.)

The "quack" thing was really noticiable.

For this, on the beyond3d forum, they have to explicitly circle "differences" (I wouldn't be able to see the difference if it weren't circled). Thus, people don't care.

The real issue is the availability of "application" mode.
