X server such as Hummingbird Exceed?

Stata 10 uses TrueType fonts for rendering antialiased (smooth) fonts.
Previous versions of Stata used bitmap fonts. When TrueType fonts exist on
the X server, the X server is able to render all text locally, and there is
a neglible difference in performance between rendering text using TrueType
fonts and rendering text using bitmap fonts.
When no TrueType font exists on the X server, all text is
rendered as a bitmap on the remote host and then sent to the X server. This
can severely affect the performance of Stata's interface and make it seem
slow to respond. Older versions of X server software may not support the
use of TrueType fonts.
To avoid any performance problems with Stata’s graphical user
interface when using a Windows X server, upgrade to the most recent version
of the X server software that supports and includes TrueType fonts. For
Hummingbird Exceed, we have confirmed that Exceed 2008 (as well as
Exceed 2007) supports TrueType fonts.
