Tips for improving the performance of your presentation

In this article


If your presentation runs slowly while you deliver it to your audience, try one or more of the following.

Adjust the performance settings

  1. On the Slide Show tab, in the Set Up group, click Set Up Slide Show.
  2. To reduce the resolution for the presentation display, and thereby increase the performance speed, do one or more of the following:
    • Under Performance, in the Slide show resolution list, click 640x480 (Fastest, Lowest Fidelity), and then click OK.

 Note   Changing the resolution may cause the slide image to shift slightly. If this happens, either choose a different resolution or click Use Current Resolution in the Slide show resolution list.

  • Under Performance, select the Use hardware graphics acceleration check box. If your computer has graphics acceleration capability, Microsoft Office PowerPoint 2007 attempts to use it when you select the check box.

ShowWhat is a graphics accelerator?

A graphics accelerator is a type of video adapter that contains its own processor to boost performance levels. These processors are specialized for computing graphical transformations, so they achieve better results than the general-purpose CPU used by your computer. These adapters free your computer's CPU to execute other commands while the graphics accelerator handles graphics computations.

Change how you use objects and animations

Windows or hardware-related actions that you can take

  • Exit all other programs.
  • Make sure that there is adequate free disk space on the computer that you will deliver your presentation on.
  • Change the color depth setting to 16-bit. Color depth is the number of color values that are assigned to a single pixel in an image. Color depth can range from 1 bit (black and white) to 32 bits (over 16.7 million colors).

For instructions on how to change the number of colors displayed on your monitor, see Microsoft Windows Help.

Clean out your TEMP folder

If you have a lot of files in your TEMP folder, it can slow PowerPoint (and other programs) down dramatically. So you'll want to periodically check and delete excess files in your TEMP folder.

To find your TEMP folder, do the following:

  1. Close PowerPoint and all other programs you are using.
  2. Click Start.
  3. Click Run.
  4. In the Open box, type %temp%.
  5. Click OK.
  6. Select the excess .tmp files, and then press DELETE.

 Note   You can usually delete any files that you find in your TEMP folder. If you get an "access error" message, it's most likely because you're attempting to delete a file that is in use.
