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. Use the Quality settings (menu: Edit > Project Settings, then select the Quality category) to select the Quality Level in the Editor for the chosen device. It is split into two main areas: the Quality matrix appears at the top; and below it, the settings for the active Quality Level appear.
Unity lets you assign a name to a given combination of quality options for easy reference. The rows of the matrix let you choose which of the different platforms each Quality Level applies to. The Default row at the bottom of the matrix is not a Quality Level in itself but rather sets the default Quality Level used for each platform (a green checkbox in a column denotes the level currently chosen for that platform). Unity comes with six Quality Levels pre-enabled but you can add your own levels.
A: The Quality Level you have defined in this project.B: The currently active Quality Level.C: The configuration of the current Quality Level.
To delete an unwanted Quality Level, use the trashcan icon (the rightmost column).
To select a Quality Level for editing, click on its name in the matrix.
To define a new Quality Level, click the Add Quality Level button and type the name for the new level in the Name property box.
然后，可选择以下部分中的哪些质量选项需要更新或设置：

The options are Disabled, 2x Multi Sampling, 4x Multi Sampling and 8x Multi Sampling.Anti aliasing smooths the appearance of polygon edges. As the level of anti-aliasing increases, so does the smoothness and the performance cost on the GPU.
MSAA is compatible only with Forward rendering. For more information on other types of anti-aliasing and compatibility, see Post processing.
