Viewport Backgrou nd parameter (page 1–38)
is tur ned on in the Viewpor t Background dialog.
WhenyouturnonFilterEnvironment
Backgrounds, the environment background is
filtered in the viewport, resulting in an antialiased
image. When you turn it off, the background
image is not filtered, resulting in an aliased,
pixelated image.
• Filtering slows down the recalculation of the
viewport background image about 30 to 40
percent. Unless you really need that smooth
display, it’s best to leave the option turned off.

viewport backgrounds when you turn on Use
Environment Background.
Low R es E nvir onment B ack grou nd—Reduces the
size of the environment background map b y half,
and then magnifies it to the size needed for the
viewport. This results in a chunkier, pixelated
appearance, but speeds the rendering in the
viewport by four times (b ecause it halves the width
and the height of the original image).
Tip: Un less you need fine detail in your
environment background, it’s best to leave this
item turned on.
