Option	Description
IDE	Select which antialiasing mode you want to apply to the IDE (including menus, tool windows, and so on): Subpixel: this option is recommended for LCD displays and takes advantage of the fact that each pixel on a color LCD is composed of red, green and blue sub-pixels. This allows smoothing text and rendering it with greater detail. Greyscale: this option is recommended for non-LCD displays or displays positioned vertically. It deals with text at the pixel level. No antialiasing: this option can be used for displays with high resolution, where non-antialiased fonts are rendered faster and may look better.
Editor	Select which antialiasing mode you want to apply to the editor: Subpixel: this option is recommended for LCD displays and takes advantage of the fact that each pixel on a color LCD is composed of red, green and blue sub-pixels. This allows smoothing text and rendering it with greater detail. Greyscale: this option is recommended for non-LCD displays or displays positioned vertically. It deals with text at the pixel level.
