Preferences: Graphics
Define the installed graphics rendering.
Check boxes allow Anti Aliasing and Text Anti Aliasing to be turned on/off. Anti aliasing means improving the smooth view of a piece shape or text. Rough edges may appear if a monitor doesn't have a resolution to present a smooth line. Anti aliasing reduces the prominence of jagged edges by surrounding the "stairsteps" with color. Although this reduces the jagged appearance of the lines, it also makes them fuzzier.
