What hardware acceleration does and why you might disable it
Hardware acceleration lets your graphics card handle visual tasks instead of your processor, which usually makes things faster and smoother. Your browser uses it to display web pages more quickly, and video apps use it to play movies without stuttering. But sometimes it causes problems: your screen flickers, videos play with weird colors, or a program crashes repeatedly.
Turning it off tells your computer to use the regular processor instead, which is slower but more stable. You lose some smoothness, but the crashes or visual glitches stop. Most people leave it on. You only disable it when something is actually broken.
Key Takeaways
- Hardware acceleration moves graphics work from your processor to your graphics card, making things faster but sometimes causing crashes or display problems.
- In Chrome, Firefox, and Edge, you disable it in Settings under System or Performance, then restart the browser completely.
- In Windows, you can disable it for individual apps through Display Settings or through the app's own preferences.
- Disabling it makes your computer work harder and things run slower, so only turn it off if you see actual problems like flickering or crashes.
- Some apps like Zoom or Discord have their own hardware acceleration toggle separate from your browser or operating system settings.
Disable hardware acceleration in Chrome
Open Chrome and click the three-line menu in the top right corner. Select Settings, then click System in the left sidebar. Look for the toggle next to "Use hardware acceleration" and switch it off. The setting says "Restart Chrome to explore changes" — close the browser completely and open it again. Restarting just the tab is not enough.
If you only want to disable it for one website, you cannot do that in Chrome. You have to turn it off for the entire browser or leave it on. Some websites work better with it off, but Chrome does not let you pick and choose per site.
Disable hardware acceleration in Firefox
Click the hamburger menu (three horizontal lines) in the top right. Select Settings, then click General in the left sidebar. Scroll down to the Performance section. Uncheck the box next to "Use recommended performance settings." This reveals another checkbox below it: "Use hardware acceleration." Uncheck that one too. Close Firefox completely and reopen it.
Firefox also lets you disable hardware acceleration just for video playback. In the same Performance section, uncheck "Play DRM-controlled content" if you only want to stop acceleration for protected videos on Netflix or similar sites. Regular videos will still use acceleration.
Disable hardware acceleration in Edge
Click the three-dot menu in the top right corner. Select Settings, then click System and performance in the left sidebar. Toggle off "Use hardware acceleration." Close Edge completely and reopen it for the change to take effect.
Edge also has a separate setting for video playback. In the same System and performance section, you can toggle off "Smooth scrolling" if that specific feature is causing problems, without disabling all hardware acceleration.
Disable hardware acceleration in Windows for individual apps
If only one program is having problems, you can disable acceleration just for that app without affecting your browser or other software. Right-click the app's icon on your desktop or in your Start menu and select Open file location. Right-click the actual program file (usually a .exe file) and choose Properties. Click the Compatibility tab.
Check the box next to "Reduced color mode" or "Run this program in a compatibility mode for" — these force the app to use older, less hardware-intensive graphics. Click explore and then OK. Open the app and see if the problem stops. If it does not, undo these changes and try a different compatibility mode from the dropdown menu.
Disable hardware acceleration in Zoom, Discord, and other apps
Many communication and streaming apps have their own hardware acceleration setting separate from your browser or Windows settings. Open Zoom and click your profile picture in the top right, then Settings. Click Video and uncheck "Hardware acceleration." In Discord, click the gear icon for User Settings, select Voice & Video, and toggle off "Hardware acceleration."
For other apps, look in Settings or Preferences for a section called Video, Graphics, Performance, or Display. The toggle is usually there. If you cannot find it, the app probably does not have a hardware acceleration setting, which means it either does not use it or does not let you control it.
When to disable it and when to leave it on
Leave hardware acceleration on unless you see a specific problem: your screen flickers or shows strange colors, videos play with artifacts or distortion, or a program crashes every time you use it. Disabling acceleration makes your processor work much harder, which drains your battery faster on laptops and makes your fan run louder. On older computers, turning it off can actually make things slower, not faster.
If disabling it does not fix the problem, turn it back on. The issue might be something else — an outdated graphics driver, a corrupted browser cache, or a problem with the website itself. Disabling acceleration is worth trying, but it is not a cure-all.
Frequently Asked Questions
Will disabling hardware acceleration make my computer slower?
Yes. Your processor has to do all the graphics work instead of your graphics card, which uses more CPU power and makes things run slower. On older computers or laptops, the slowdown can be noticeable. Only disable it if you have an actual problem to fix.
Do I need to disable hardware acceleration if my graphics driver is outdated?
Not necessarily. An outdated driver is often the real cause of flickering or crashes. Update your graphics driver first through Windows Update or your graphics card manufacturer's website. If that fixes the problem, leave hardware acceleration on. Only disable it if updating the driver does not help.
Can I disable hardware acceleration for just one website?
Not in most browsers. Chrome, Firefox, and Edge let you disable it for the entire browser, but not per website. If one website causes problems, you can disable acceleration in your browser settings, use a different browser for that site, or contact the website to report the issue.
Does disabling hardware acceleration affect gaming?
Yes, significantly. Games rely heavily on hardware acceleration for smooth frame rates. Disabling it will make games run much slower and choppier. Only disable it if a game is crashing, and try updating your graphics driver first.
What if I disable hardware acceleration and nothing changes?
The problem might not be related to acceleration. Try clearing your browser cache, restarting your computer, or updating your graphics driver. If the issue persists, re-enable hardware acceleration and look for other causes like browser extensions, malware, or a problem with the specific website or app.
