How to Fix Hardware Acceleration Not Working Issues on Windows 11: Step-by-Step Solutions

Hardware acceleration helps your computer run graphics-intensive tasks more smoothly by using your GPU instead of the CPU. When it stops working on Windows 11, you might notice slow performance or glitches in videos and apps. Fixing this issue can improve your overall system responsiveness and visual experience.

In this guide, you will find easy-to-follow steps to troubleshoot and fix hardware acceleration problems on Windows 11. Each solution is explained clearly, so even beginners can understand and apply them.

By following these methods in order, you can identify and resolve the issue without unnecessary complexity. Let’s get started and bring back smooth performance to your PC.

If you want to fix hardware acceleration not working, this article covers all the basics and some advanced tips too.

Quick Note: Before You Begin

  • Make sure your Windows 11 is fully updated. Updates often include important fixes that can resolve hardware issues.
  • Check if your graphics drivers are installed and up to date, as outdated drivers are a common cause of hardware acceleration problems.
  • Confirm that your device supports hardware acceleration—older hardware might not support it fully.
  • Restart your PC before troubleshooting. Sometimes a simple reboot fixes temporary glitches.

Step 1: Enable Hardware Acceleration in Windows Settings

Windows 11 allows you to toggle hardware acceleration on or off. Sometimes, it might be disabled accidentally. Here’s how to check and enable it:

  1. Click the Start button and select Settings (gear icon).
  2. Go to System and then select Display.
  3. Scroll down and click on Graphics settings.
  4. Under “Hardware-accelerated GPU scheduling”, make sure the toggle is turned On.
  5. If it was off, turn it on, then restart your computer to apply changes.

Why this is important: Enabling hardware acceleration here allows Windows to offload some processing tasks to your GPU, which can boost performance.

Step 2: Update Graphics Drivers

Outdated or corrupted graphics drivers often cause hardware acceleration problems. Updating them ensures compatibility and better performance.

  1. Right-click the Start button and select Device Manager.
  2. Expand the Display adapters category to see your graphics card.
  3. Right-click your graphics device and choose Update driver.
  4. Select Search automatically for drivers and wait for Windows to find and install updates.
  5. Restart your PC once the update finishes.

Alternative method: Visit your GPU manufacturer’s website (NVIDIA, AMD, Intel) to download and install the latest driver manually.

Step 3: Check Graphics Settings for Individual Apps

Windows 11 lets you assign hardware acceleration preferences per app. Sometimes, apps may be set to use the CPU instead of the GPU.

  1. Open Settings and navigate to System > Display > Graphics settings.
  2. Scroll down to the “Choose an app to set preference” section.
  3. Select the app you want to fix (or browse to add it), then click Options.
  4. Choose High performance to force hardware acceleration and click Save.
  5. Restart the app and check if acceleration works better.

Why this helps: Some apps default to software rendering, which is slower. Assigning them to use the GPU improves performance.

Step 4: Adjust Registry Settings (Advanced)

If the above steps don’t help, you can modify the Windows registry to enable hardware acceleration manually. Be careful and follow exactly:

  1. Press Windows + R, type regedit, and press Enter to open the Registry Editor.
  2. Navigate to:
    HKEY_CURRENT_USERSoftwareMicrosoftAvalon.Graphics
  3. If the Avalon.Graphics key does not exist, create it by right-clicking Microsoft, selecting New > Key, and naming it Avalon.Graphics.
  4. Within Avalon.Graphics, right-click the right pane, choose New > DWORD (32-bit) Value, name it DisableHWAcceleration.
  5. Double-click DisableHWAcceleration and set the value to 0 to enable hardware acceleration.
  6. Close Registry Editor and restart your PC.

Note: A value of 1 disables hardware acceleration. Setting it to 0 forces it on.

Step 5: Disable Conflicting Software

Sometimes third-party software like screen recorders, video players, or custom themes can interfere with hardware acceleration.

  • Temporarily disable or uninstall any recently added software.
  • Check if hardware acceleration starts working after that.
  • If yes, look for updates or alternatives to that software.

Frequently Asked Questions (FAQs)

What is hardware acceleration?

Hardware acceleration means using your computer’s GPU to perform tasks faster than the CPU alone. It helps improve graphics and video performance.

How do I know if hardware acceleration is enabled?

You can check in Windows Settings under Display > Graphics settings. Also, some apps have their own hardware acceleration toggles.

Can hardware acceleration cause problems?

Yes, sometimes hardware acceleration can cause crashes or glitches if the drivers or hardware are incompatible or outdated.

Is it safe to edit the registry?

Editing the registry can be risky if done incorrectly. Always back up your registry before making changes.

Why does hardware acceleration not work after a Windows update?

Windows updates can reset settings or introduce driver conflicts. Updating your graphics drivers after an update usually fixes this.

Can I force hardware acceleration in apps like Chrome or Firefox?

Yes, browsers like Chrome and Firefox have settings to enable or disable hardware acceleration independently within their settings menus.

When Nothing Works

If you have tried all the above steps and hardware acceleration still does not work, consider the following:

  • Run Windows Update again to ensure no missing patches.
  • Use the System File Checker tool by opening Command Prompt as administrator and running sfc /scannow to repair corrupted system files.
  • Perform a clean install of your graphics drivers using tools like Display Driver Uninstaller (DDU) to remove old driver remnants.
  • Contact your PC or GPU manufacturer’s support for advanced troubleshooting.
  • Refer to official Microsoft support pages for Windows 11 hardware acceleration issues: https://support.microsoft.com

Conclusion

Hardware acceleration can greatly improve your Windows 11 experience by offloading work to your GPU. When it stops working, it can slow down your system or cause glitches.

Start with simple steps like enabling hardware acceleration in settings and updating your graphics drivers. If needed, adjust app preferences or modify the registry carefully. Avoid conflicts by checking for interfering software.

By following this guide step-by-step, you can fix most hardware acceleration problems and enjoy smoother performance. Remember to keep your system and drivers updated regularly to prevent future issues.
