Laggy or choppy behavior in AutoCAD with large amounts of Text (TTF)

May 2, 2022 Ryan Wunderlich

Issue:

In AutoCAD or AutoCAD-based products, you have significant performance issues on layouts or areas of the screen that contain large amounts of text

Causes:

This is generally related to the font used in the displayed Text Style.  More specifically, when using True Type Fonts (TTF), AutoCAD-based products actually render the text like a bitmap, and not as vectors (with text that has a fill or thickness).  When you have large amounts of text, and you have a complex TTF assigned to the text style, you will see an immediate lag when navigating or doing commands and commands like Zoom and PAN will be very choppy.

Solution:

There are only a few things you can do to remedy this:

  1. Use a different font in the Text Style
  2. Use a different font during the editing, then change it back for printing
  3. Be aware and accept the lag when in those layout tabs
