Anisotropic + Anti-Aliasing Performance
If you're satisfied with the Quincunx mode, then Parhelia has no chance in terms of performance. Moreover, the disadvantage of unclear textures in Quincunx mode is compensated for by anisotropic filtering. If you run the GeForce 4 with 4x at the same level of quality (LV2), then this card is significantly better than Parhelia. Parhelia only gains a slight advantage starting with the higher resolutions.
