Advanced Options Page Advanced Options Page
The Advanced Options page (Figure 17) enables you to set various
application or platform specific parameters that can affect
performance. A series of check boxes let you enable or disable certain
features.
Adjust for model imprecision Adjust for model imprecision
When checked, hardware sub-pixel precision is used to eliminate
distortion resulting from 3D model imprecision.
Always draw with anti-aliased lines Always draw with anti-aliased lines
When checked, all lines will be drawn anti-aliased; otherwise, lines will
not be drawn anti-aliased unless specifically requested by the
application. Enabling this feature results in smoother lines at a slight
performance cost. Recommended for use in applications where text
fonts are drawn using OpenGL lines (e.g., some international versions
of Pro/ENGINEER). For best performance with most OpenGL and
Heidi applications, leave this option unchecked. If you select certain
memory options, this alternative is grayed out and unavailable.
