Try opening or dragging dialogs around to see if performance has improved.
If it has, do the following:
■ If the software was originally configured for OpenGL, try configuring 3ds
Max for Direct3D and see if performance is improved. Or vice-versa.
■ Verify that your graphic card supports your preferred display configuration
choice. Some cards do not fully support OpenGL or Direct3D.
■ Visit the Web site of your graphic card manufacturer and see if they have
any newer video drivers that you can download and install.
Sluggish Command Response
Sluggish command response is closely related to the previous situation. If you
create an object such as a Box, you might notice that the cursor suddenly
slows down when you drag it into a viewport. Clicking the corners to set the
length, width and height is equally time-consuming. Once again, the likely
cause is video-related.
1 Start 3ds Max.
2 From the Customize menu, choose Preferences.

5 Click OK to close the Graphic Driver Setup dialog.
You will be informed that you have to restart 3ds Max for the change to
take effect.
