It is clear that ATI and NVIDIA have somewhat different optimisations. In colour levels, ATI shows dithering (perhaps due to a lower precision, 5 bits per component instead of 8), while NVIDIA has monotonous areas with no smooth gradient, as is the case with canonical trilinear filtering. Visually, NVIDIA without optimisation has the best filtering, and in general, we would arrange the contestants in the following order:

  • GeForce 6800 without optimisation
  • RADEON 9800
  • RADEON X800
  • GeForce 6800 with optimisation

Interestingly, X800 seemed a bit worse than its RADEON fellow to us, but it's obviously just a matter of optimisation parameters, and they can probably be changed with other driver versions. As for the optimisation algorithm itself, it seemed similar in RADEON 9800 and X800. Certainly, our readers may form their own charts, but our task was just to provide them with carefully selected examples, so now it's up to them to decide.
