For a square power-of-two texture, each successive level has one quarter as many texels; the complete chain adds approximately one third to base-level storage. [1]\n\nAt oblique angles, the footprint becomes elongated. Anisotropic filtering accounts for that shape instead of treating both directions identically. [2] Its maximum setting is a quality limit, not a promise of a fixed sample count or equal performance across devices.
