When performing anisotropic filtering when sampling a texture in a graphics processing system, a number of positions for which to sample the texture along an anisotropy direction is determined. When the determined number of positions for which to sample the texture along the anisotropy direction is a non-integer value that exceeds a lower integer value by more than a threshold amount, samples are taken along the anisotropy direction in the texture for a number of positions corresponding to the next higher multiple of 2 to the determined non-integer number of positions to be sampled. When the determined number of positions for which to sample the texture along the anisotropy direction does not exceed the lower integer value by at least the threshold amount, samples are taken along the anisotropy direction in the texture for a number of positions corresponding to the lower integer value.
