Slow performance

Published date: 2008-Aug-27

Applies to:
AutoCAD® 2009
AutoCAD® 2008

Issue

You experienced unusually slow performance when using AutoCAD®, especially when working in palettes (for example, Properties palette, Design Center, Tool Palettes, Sheet Set Manager, Layer Manager).

Solution

To improve performance, try the following:

  1. In AutoCAD® 2009, enable the AutoCAD Classic workspace.
  2. Dock any desktop element and make sure that none of the palettes are floating.
  3. Turn off any unused palettes.
  4. Update the graphics driver.
  5. If using multiple monitors, see if using only a single monitor improves performance.
    (The graphics hardware certification tests conducted by Autodesk are performed on systems using only a single video card with a single monitor attached.)
  6. Reduce the level of hardware acceleration
    • Click Start menu (Windows) > Control Panel.
    • In the Control Panel, double-click Display.
    • In the Display Properties dialog box, click the Settings tab.
    • Click the Advanced button.
    • On the Troubleshoot tab, adjust the Hardware Acceleration slider as needed. 
  7. If you are using an nVidia graphics card adapter, check to see if a process called nwiz.exe is being loaded when AutoCAD is started. Disable it from being loaded by default. If you have installed the nView Desktop Manager, make sure no additional features are used. Uninstall it from Add or Remove programs in Windows, if possible.
