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: if you encounter any issues disabling the hardware acceleration based on the instructions below, we recommend contacting Google or Firefox directly.
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. As noted above, we recommend using Google Chrome as we’ve found it works best to watch Udemy courses.
