Advanced Quality settings
When you choose Custom in the Quality section of the Render pop-up menu (or in the View > Quality menu), the Advanced Quality Options dialog appears.
The Advanced Quality Options dialog provides additional controls to fine-tune rendering performance and quality. It contains the following items:
Quality: A pop-up menu that sets rendering quality. These settings are identical to the Quality settings in the Render pop-up menu. (For more information on the Render popup menu, see Custom Canvas view options.)
Choose one of four settings from this pop-up menu (each setting activates different options in the dialog):
Draft: None of the quality options are selected, and the Text Quality parameter is set to Low. This option allows optimal project interactivity.
Normal: “Shape anti-aliasing” is selected, and the Text Quality parameter is set to Medium. This option allows project interactivity that is slower than Draft, but much faster than Best.
Best: “High-quality resampling,” “Shape anti-aliasing,” and “Anti-alias 3D intersections” are selected. Text render quality is set to High. This option slows down project interactivity.
Custom: Lets you set your own combination of render settings.
High Quality Resampling: Turns on high-quality resampling (increasing or reducing the number of pixels in an image).
Text Quality: A pop-up menu that sets text-rendering quality to Low, Medium, or High. When High is selected, project interactivity may slow.
Shape anti-aliasing: Renders shapes at a higher resolution, then scales objects back to regular resolution to ensure smooth edges.
Anti-alias 3D intersections: Renders objects intersecting in 3D space at a higher resolution, then scales objects back to regular resolution to ensure smooth edges.
