Tweaking Performance Levels

Problems can also occur when hardware such as graphics and audio accelerators don't properly support advanced features. Windows 98 lets you troubleshoot these problems by selectively turning off individual features until you find a profile that works properly.

To scale back graphics acceleration features, follow these steps:

  1. Click Start | Settings | Control Panel, and select the System icon.
  2. Click the Performance tab, and then click the Graphics button to display the Hardware Acceleration slider bar.
  3. Drag the Hardware Acceleration slider bar to the left one notch and click OK.
  4. Click Yes when Windows 98 tells you to restart the system. If the problem disappears, you know your graphics hardware is not able to effectively provide full capabilities.

You can access this same control from the Windows 98 Control Panel by selecting the Display icon, clicking the Settings tab, and then clicking the Advanced button. In the dialog box that comes up, click the Performance tab, and the same control appears.


You can tweak audio capabilities in much the same way. If you are experiencing audio problems, try disabling some of the hardware acceleration in an effort to ferret out a problem.

  1. From the Windows 98 Control Panel, select the Multimedia tab.
  2. In the Audio sheet, click the Advanced Properties button.
  3. Click the Performance tab to display the audio performance controls
  4. Drag the Hardware Acceleration slider bar to the left one notch to disable part of the audio acceleration capabilities.
  5. Click OK, and then click Yes to restart the system when prompted.
