Using texture minification filters

A Minification filter controls how a texture is interpolated when a scene pixel maps to multiple texture pixels (texels)

FASTEST Use fastest method
NICEST Use best looking method
BASE_LEVEL_POINT Use nearest texel in level 0 map
BASE_LEVEL_LINEAR Bilinearly interpolate 4 nearest texels in level 0 map
MULTI_LEVEL_POINT Use nearest texel in mip-mapped maps
MULTI_LEVEL_LINEAR Bilinearly interpolate 4 nearest texels in mip-mapped maps
