• Click "OK" to save the changes.

Disabling hardware acceleration can help alleviate high CPU usage in Adobe Reader, especially if your computer's hardware is not fully compatible.

Reducing the Number of Thumbnail Previews

Adobe Reader generates thumbnail previews for faster navigation within PDF documents. However, generating multiple thumbnail previews can be resource-intensive and increase CPU usage. To reduce the number of thumbnail previews:

• Open Adobe Reader and go to the "Edit" menu.
• Select "Preferences" and navigate to the "Page Display" category.
• Under the "Page Content and Information" section, reduce the value in the "Maximum number of pages to cache" field.
• Click "OK" to save the changes.

By reducing the number of thumbnail previews, you can decrease the CPU usage associated with generating and caching these previews.

Adjusting Browser Integration Settings

Adobe Reader integrates with web browsers to provide seamless PDF viewing. However, this integration can sometimes lead to high CPU usage. To adjust browser integration settings:

• Open Adobe Reader and go to the "Edit" menu.
• Select "Preferences" and navigate to the "Internet" category.
• Under the "Web Browser Options" section, uncheck the options for browser integration.
• Click "OK" to save the changes.

Disabling browser integration can help reduce CPU usage if you primarily use Adobe Reader as a standalone application rather than within a web browser.

Clearing Cache and Temporary Files

Over time, Adobe Reader accumulates cache and temporary files, which can impact its performance and contribute to high CPU usage. To clear the cache and temporary files:

• Close Adobe Reader if it is open.
• Press Windows + R on your keyboard to open the Run dialog.
• Type %appdata%\Adobe and press Enter.
• Locate the "Acrobat" or "Reader" folder and delete its contents. Note: Deleting these files will not affect your PDF documents or settings.
• Restart Adobe Reader and check if the CPU usage has improved.

Clearing the cache and temporary files can help resolve any issues caused by outdated or corrupted files.

By implementing these additional steps, you can potentially reduce Adobe Reader Cef high CPU usage and improve its overall performance.
