Unity allows you to set the level of graphical quality it attempts to render. Generally speaking, quality comes at the expense of framerate and so it may be best not to aim for the highest quality on mobile devices or older hardware since it tends to have a detrimental effect on gameplay.
Rendering
Property Function
Pixel Light Count Set the maximum number of pixel lights when Unity uses Forward Rendering
Texture Quality Choose whether to display Textures at maximum resolution or at a fraction of this (lower resolution has less processing overhead). The options are Full Res, Half Res, Quarter Res and Eigth Res.
Anisotropic Textures Choose if and how Unity uses anisotropic Textures. The options are Disabled, Per Texture and Forced On (that is, always enabled)
AntiAliasing Choose the level of antialiasing that Unity uses. The options are Disabled, 2x Multi Sampling, 4x Multi Sampling and 8x Multi Sampling.
