In Microsoft Edge, open edge://settings/system, change Use graphics acceleration when available, and restart the browser. Check edge://gpu afterward to see whether video, WebGL, canvas, and other features are using hardware acceleration or software rendering.
What graphics hardware acceleration does in Edge
Graphics hardware acceleration lets Edge send suitable rendering and media work to the computer’s graphics processing unit (GPU) instead of handling everything on the CPU. The GPU can process video frames, page compositing, WebGL scenes, canvas drawing, and other graphics operations in supported configurations. The practical goal is smoother playback and responsive graphics, particularly with high-resolution video and visually intensive pages.

Acceleration is not an all-or-nothing guarantee. Edge reports the status of individual graphics features, and a browser can use the GPU for one operation while falling back to software for another. The result depends on the operating system, GPU model, driver, video codec, Edge version, and whether a particular feature is supported on that device.
Turning the option off forces Edge toward software rendering. That can remove crashes, flicker, freezes, black video, or meeting glitches caused by a driver or GPU rendering path, but it also moves more work to the CPU. Microsoft specifically warns that software rendering of video, WebGL, and canvas content increases CPU usage.

Turn hardware acceleration on or off
- Open Edge. Use the desktop browser rather than a mobile Edge installation; the managed policy described later does not support Android or iOS.
- Open the system settings page. Enter
edge://settings/systemin the address bar and press Enter. You can reach the same page through Settings > System and performance. - Locate the control. Find Use graphics acceleration when available.
- Choose the mode. Turn the toggle on to allow GPU acceleration, or turn it off to force software rendering as far as Edge and the operating system permit.
- Restart Edge completely. Close the browser windows and relaunch Edge. Microsoft’s troubleshooting guidance treats a restart as part of applying the change; leaving an old browser process running can make the result appear unchanged.
The setting is an availability preference, not a command to accelerate every feature. With the switch on, Edge uses hardware acceleration when the platform, driver, and feature support it. With the switch off, Edge avoids the normal GPU acceleration path, although the exact fallback can vary by media and rendering component.
Confirm which features are using the GPU
After restarting, enter edge://gpu in the address bar. The page’s Graphics Feature Status section lists individual capabilities and usually labels them as hardware accelerated, software only, unavailable, or another platform-specific state.
Check video decoding separately
For a playback problem, look specifically for Video Decode. Microsoft’s troubleshooting example is Video Decode: Hardware accelerated. That line is more useful than assuming that a different feature, such as WebGL, proves that video is also using the GPU.
Interpret mixed results correctly
- Hardware accelerated: Edge is using the GPU path for that feature under the current conditions.
- Software only: The feature is being processed by the CPU or a software implementation. This can be expected for an unsupported codec, a blocked feature, an old driver, or a deliberate troubleshooting setting.
- Unavailable or disabled: The platform, driver, policy, or browser configuration prevents that feature from being used.
- Different statuses for different rows: Do not treat this as a contradiction. Video decode, compositing, WebGL, rasterization, and canvas can have separate support decisions.
If the toggle is on but a feature remains software only, inspect that feature’s own status rather than assuming that Edge is ignoring the setting. Update the graphics driver, restart Edge, and check the status again.
When disabling acceleration is a useful test
Disable the option when a repeatable problem appears during graphics-heavy work and you need to distinguish a GPU path problem from a general browser or network problem. Typical symptoms include:

- Powered by GeForce RTX 5070 Ti
- Integrated with 16GB GDDR7 256bit memory interface
- PCIe 5.0
- WINDFORCE cooling system
- Video that flickers, freezes, displays a black frame, or shows corrupted blocks.
- WebGL demonstrations or browser games that crash, render incorrectly, or turn the page white.
- Canvas-based editors, maps, or dashboards that flash or stop drawing.
- Video calls or online meetings with unstable preview, frozen frames, or rendering artifacts.
- Edge windows that become unresponsive shortly after playing video or opening a graphics-intensive site.
Switching acceleration off is a diagnostic change, not proof that the GPU is defective. If the problem disappears after a restart, the GPU path, its driver, a codec interaction, or a browser rendering bug is implicated. If the symptom remains, investigate the site, extension, operating-system graphics stack, camera or microphone path, and network separately.
A practical troubleshooting sequence
- Record the symptom. Note the site, video format if known, monitor setup, whether the issue occurs in a meeting, and whether CPU usage rises sharply. This makes it easier to compare the two rendering modes.
- Test software rendering. Open
edge://settings/system, turn off Use graphics acceleration when available, restart Edge, and repeat the exact task that failed. - Compare the result. Improvement points toward a GPU, driver, codec, or hardware-rendering conflict. No change means acceleration may not be involved, or the affected feature may already have been software rendered.
- Update the GPU driver. Install the current driver supplied by the computer or graphics-card manufacturer for the operating system and GPU model. Restart the computer if the installer requests it, then restart Edge.
- Retest with acceleration enabled. Turn the Edge option back on, restart, and repeat the task. Keeping the normal mode enabled is preferable when the updated driver resolves the fault.
- Inspect feature status. Use
edge://gpuand read the individual rows, especially Video Decode for playback. Do not rely on a single overall impression of the page. - Collect media diagnostics when video is involved. Open
edge://media-internalsin another tab while reproducing the problem. The page can expose media-player events and pipeline details that help identify decode or playback failures.
Microsoft also recommends toggling the setting off and on again, restarting, updating the graphics driver, and checking the diagnostic pages. Perform one change at a time when possible; otherwise, you cannot tell which action fixed the problem.

What happens when Edge falls back to software
With software rendering, the CPU performs more of the video, WebGL, and canvas work. A modern multi-core computer may handle ordinary pages without an obvious difference, while high-resolution video, many animated tabs, large canvases, or several simultaneous meetings can increase CPU load, fan noise, heat, and battery drain.
Some playback paths can use software video decoding such as FFmpeg when acceleration is disabled. The exact path depends on the media format and Edge’s implementation, so a software fallback is not evidence that every video uses the same decoder. Check edge://gpu and, for media-specific details, edge://media-internals.
Conversely, hardware acceleration can reduce CPU work but still produce a poor result if the driver is unstable, the GPU is underpowered for the workload, a codec is unsupported, or an external display introduces a compatibility issue. There is no universal performance percentage or benchmark that applies to every Edge installation.

Enable versus disable: choosing the right mode
| Decision point | Acceleration enabled | Acceleration disabled |
|---|---|---|
| Rendering path | Uses the GPU when Edge and the platform support the feature. | Uses software rendering for the normal browser acceleration path. |
| Likely benefit | Can provide smoother video and more responsive graphics, including high-resolution streams. | Can improve stability when a driver or GPU rendering path causes glitches. |
| CPU impact | Often moves supported graphics work away from the CPU, subject to driver and feature support. | Video, WebGL, and canvas work can raise CPU usage because Microsoft identifies software rendering as more CPU intensive. |
| Best troubleshooting use | Normal operating mode after the driver and browser are stable. | Controlled test for flicker, freezing, crashes, corrupted rendering, or meeting-video problems. |
| How to verify | Check edge://gpu, including Video Decode. |
Check the same page for software-only status and use edge://media-internals for media diagnostics. |
| Expected result | Only supported features are accelerated; other rows may remain software only. | More features use software paths, but exact behavior varies by codec and component. |
Managed computers and the HardwareAccelerationModeEnabled policy
Organizations can control the same behavior with Microsoft Edge’s HardwareAccelerationModeEnabled Boolean policy. Microsoft defines the policy this way: “If you enable this policy, or leave it unconfigured, graphics acceleration is utilized if it’s available. If you disable this policy, turns off graphics acceleration.”
That means an enabled or unconfigured policy permits acceleration when available, while a disabled policy turns it off. The policy is not per-profile, so changing profiles does not bypass an administrative setting. A browser restart is required for a refreshed policy value to take effect.
Windows policy location
In Windows administrative templates, the policy is under Administrative Templates/Microsoft Edge. The corresponding registry value is:
SOFTWAREPoliciesMicrosoftEdgeHardwareAccelerationModeEnabled
The value is Boolean. A managed deployment should set it through the organization’s approved policy system rather than asking individual users to edit the registry. If Edge reports that a setting is managed, contact the administrator before changing local configuration.

Changing the switch but not restarting
Edge can continue using processes created before the change. Close all Edge windows, confirm that the browser is no longer running, reopen it, and then inspect edge://gpu.
Assuming one accelerated row means everything is accelerated
Graphics Feature Status is component-specific. If video is the concern, verify Video Decode rather than relying on WebGL or compositing status. A mixed list is normal when different features have different driver or codec requirements.
Do these 3 things before closing this tab:

Software rendering may hide a driver conflict but can increase CPU use during video, WebGL, canvas, and meeting workloads. After updating the driver, retest with the toggle enabled and keep the mode that is stable for the workload you actually use.

Blaming the internet connection for a rendering artifact
Buffering caused by a network problem and flickering caused by a GPU path can look similar. Use the same stream after changing acceleration, and inspect media diagnostics. A visual corruption pattern that vanishes only when acceleration is disabled points to rendering rather than bandwidth.
Expecting a setting to fix unsupported hardware
The toggle cannot add codec, driver, or GPU capability that the device does not have. If a feature remains software only with an up-to-date driver and acceleration enabled, that status may reflect platform support rather than a broken switch.
Performance and compatibility limits
Microsoft notes that feature availability and functionality can vary by device type, market, and browser version. The same Edge release can therefore show different statuses on two computers with different GPUs, drivers, codecs, displays, or operating-system builds.

Quick Recap
A concise decision checklist
- Need normal GPU use? Enable the toggle, restart Edge, and confirm the relevant feature on
edge://gpu. - Seeing flicker, freezes, crashes, or black video? Disable the toggle, restart, and repeat the task.
- Did disabling help? Update the GPU driver, re-enable acceleration, restart, and test again.
- Is video still problematic? Check Video Decode on
edge://gpuand inspectedge://media-internals. - Is the option managed? Check the organization’s Edge policy; the Windows and macOS policy value is
HardwareAccelerationModeEnabled, and policy changes require a browser restart. - Using Android or iOS? The desktop policy does not apply to those platforms.
