How to disable hardware acceleration on your browser
The instructions below outline how to disable hardware acceleration on either a Google Chrome or Firefox browser.
- Please note: we recommend consulting with your organization’s IT department before doing so.
Disabling hardware acceleration in Google Chrome:
- Open Google Chrome.
- Click Chrome > Preferences.
- Click on "Systems" on the left-hand side to find hardware acceleration. The hardware acceleration option may be referred to as “graphics acceleration”.
- Uncheck "Use hardware acceleration when available" or “Use graphics acceleration when available” and restart Google Chrome.
Disabling hardware acceleration in Firefox:
- Open Mozilla Firefox; click on the Firefox menu button and select "Settings".
- On the "General" tab, scroll down to "Performance". Make sure the "Use recommended performance settings" checkbox is disabled and disable the "Use hardware acceleration when available" option.
- Restart the browser.
If you are accessing the courses via Safari:
Unfortunately, Safari does not allow users to turn hardware acceleration on and off. If you’re not already using Google Chrome, we recommend using it, as we’ve found it works best to watch Udemy courses.
