简单来说，硬件加速^{(Hardware Acceleration)}一词意味着使用计算机的硬件执行特定任务和功能比使用软件更快。这也允许图形的平滑渲染。在大多数处理器中，指令是按顺序执行的，即一条一条地执行，但是如果您使用某种技术稍微修改相同的进程，您可以更快地执行它们。这个想法是将所有图形和文本渲染从中央处理单元^{(Central Processing Unit)}移动到图形^(Graphics) 处理单元^{(Processing Unit)}，从而获得更好的性能。

有时松散地称为图形加速器或浮点加速器，硬件加​​速器可以显着提高应用程序的性能。硬件加速器^{(Hardware Accelerator)}一词现在已被更常见且描述性较差的术语（例如显卡和视频卡）松散地取代。

虽然这些设置在Windows中最好保留其默认值，但如果您愿意，您可以关闭或禁用硬件^(Hardware) 图形^(Graphics) 加速^{(Acceleration)}或减少硬件加速——^{(Hardware Acceleration –)}尤其是当您在软件中看到图形^(Graphics)错误时。完全关闭硬件加速^{(Hardware Acceleration)}将以软件渲染模式运行应用程序'。

在继续之前，您应该知道并非所有计算机系统都支持这一点。大多数使用NVIDIA或AMD/ATI显卡的新计算机将无法更改加速量。这些选项在旧系统和使用板载视频的系统上可用。

更新：^(UPDATE:) AMD和NVIDIA现在允许您在Windows 10 v2004 及更高版本中启用或禁用硬件加速。

您需要打开或关闭硬件加速 GPU 调度。^{(Hardware-accelerated GPU scheduling)(Hardware-accelerated GPU scheduling)}

在Windows 11/10中禁用硬件加速^{(Hardware Acceleration)}

Windows 11/10中禁用硬件加速，请执行以下步骤：

1. 右键单击^{(Right-click)}桌面并^(Desktop)选择显示^(Display)设置选项。

That’s it!

要在Windows 8/7中禁用或减少硬件加速^{(Hardware Acceleration)}，首先，右键单击桌面^(Desktop)，然后从上下文菜单中选择个性化^{(Personalization)}选项。

然后，从窗口的左侧面板中选择“显示^(Display)”，然后单击“更改^(Change)显示设置”。

接下来，单击“高级设置”。

这将打开您的监视器^(Monitor)和图形属性^{(Graphics Properties)}框。然后，您可以通过其疑难解答^{(Troubleshoot)}选项卡按照上面给出的说明的后半部分进行操作。

这是您在Windows 11/10/8/7中启用、禁用或更改硬件加速级别的方法。

禁用硬件加速按钮灰显

如果您发现该选项显示为灰色，请检查您的硬件是否允许，并确保您已更新驱动程序。您还可以查看以下注册表项中是否存在DWORD DisableHWAcceleration并且其值为0。

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Avalon.Graphics\

如果不存在，则创建一个新的 DWORD DisableHWAcceleration。值1禁用硬件加速。值 0 启用硬件加速，前提是系统满足硬件加速要求。

您可以使用上述注册表^(Registry)方法在Windows 10中禁用硬件加速。

新设置无法保存到注册表

如果您收到意外错误，新设置无法保存到注册表^{(Unexpected error, The new settings could not be saved to registry )}消息框；那么您可以尝试以下方法：

1. 访问制造商的网站以下载并安装最新的驱动程序^{(download and install the latest drivers)}
2. 运行显示质量疑难解答
3. 运行硬件和设备疑难解答。

如何禁用硬件加速？

Windows 11/10中禁用硬件加速，您需要按照上述指南进行操作。换句话说，您需要打开“高级显示设置^{(Advanced display settings )}”Windows 设置面板，转到“显示适配器^{(Display adapter )}”部分并切换到“疑难解答”^{(Troubleshoot )}选项卡。然后，单击更改设置^{(Change settings )}按钮，并将栏移动到无^{(None )}部分。

Does Windows 11/10有硬件加速吗？

是的，Windows 11 和Windows 10具有可以轻松启用或禁用的硬件加速。不论是声卡还是显卡，都可以使用向导开启或关闭Windows 11/10中的硬件加速，如前所述。

我应该禁用硬件图形加速吗？

这取决于您所处的情况。硬件^(Hardware)加速应该可以帮助您获得更好的用户体验。但是，如果您在计算机上使用某个应用程序时发现任何崩溃或延迟问题，关闭硬件加速可能对您很方便。

How to Turn off or Disable Hardware Acceleration in Windows 11/10

Іn simple terms, the tеrm Hardware Acceleration means using the computer’s hardware for performing a certain task and function faster than would be possible using the software. This also allows for smooth rendering of graphics. In most processors, instructions are executed sequentially, i.e., one by one, but you can perform them faster if you modify the same process a bit using some technique. The idea is to move all graphics and text rendering from the Central Processing Unit to the Graphics Processing Unit, thereby getting better performance.

Sometimes loosely called as graphics accelerators or floating-point accelerators, hardware accelerators can improve the performance of an application significantly. The term Hardware Accelerator has now been loosely replaced by more common and less descriptive terms such as graphics cards and video cards.

While the settings are best left at their default values in Windows, you can, if you wish to, turn off or disable Hardware Graphics Acceleration or reduce Hardware Acceleration – especially if you see Graphics error in your software. Turning off the Hardware Acceleration completely will run the application in software rendering mode’.

Before you proceed, you should know that not all computer systems support this. Most new computers using NVIDIA or AMD/ATI graphics cards will not have the ability to change the amount of acceleration. These options are available on older systems and those which use the onboard video.

UPDATE: AMD and NVIDIA now allow you to enable or disable hardware acceleration in Windows 10 v2004 and later.

You need to toggle Hardware-accelerated GPU scheduling On or Off.

Disable Hardware Acceleration in Windows 11/10

To disable hardware acceleration in Windows 11/10, follow these steps:

1. Right-click on the Desktop and select the Display settings option.
2. Click the Advanced display settings option.
3. Select the Display adapter.
4. Switch to the Troubleshoot tab.
5. Click the Change settings button.
6. Click the bar and move it to the None.
7. Click the OK button.

Let’s check out these steps in detail.

The Hardware Acceleration tab in Windows allows you to specify the performance of the graphics hardware present on your PC. In Windows 11/10 right-click on the desktop, select Display settings.

The Display Settings will open. Scroll down a bit, and you will see Advanced display settings.

Click on Display adapter properties link.

If your current display driver allows you to change the settings, you will be able to see the Change settings button. Click on it.

Now, the Display Adapter Troubleshooter will appear on your computer screen. Move the pointer to the extreme left to disable or reduce the hardware acceleration and click on OK. If you are having problems with your graphics hardware, these settings can help you troubleshoot display-related problems.

That’s it!

To disable or reduce Hardware Acceleration in Windows 8/7, first, right-click on the Desktop and from the context menu, choose the Personalization option.

Then, select Display from the left panel of the window and click on ‘Change display settings’.

Next, click on ‘Advanced settings’.

This will open your Monitor and Graphics Properties box. You can then follow the latter part of the instructions given above via its Troubleshoot tab.

This is how you can enable, disable, or change the level of hardware acceleration in Windows 11/10/8/7.

Disable hardware acceleration button greyed out

If you find that the option is grayed out, check if your hardware permits it and ensure that you have updated drivers. You may also see if DWORD DisableHWAcceleration exists in the following registry key and that it has a value of 0.

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Avalon.Graphics\

If it does not exist, create a new DWORD DisableHWAcceleration. A value of 1 disables hardware acceleration. A value of 0 enables hardware acceleration, provided the system meets hardware acceleration requirements.

You can use the above Registry method to disable hardware acceleration in Windows 10.

The new settings could not be saved to registry

If you receive an Unexpected error, The new settings could not be saved to registry message box; then you may try the following:

1. Visit the manufacturer’s website to download and install the latest drivers
2. Run Display Quality Troubleshooter
3. Run Hardware and Devices Troubleshooter.

How do I disable hardware acceleration?

To disable hardware acceleration in Windows 11/10, you need to follow the guide mentioned above. In other words, you need to open the Advanced display settings Windows Settings panel, go to the Display adapter section and switch to the Troubleshoot tab. Then, click the Change settings button, and move the bar to the None section.

Does Windows 11/10 have hardware acceleration?

Yes, Windows 11 and Windows 10 have hardware acceleration that you can enable or disable easily. Whether it is about the sound or video card, you can turn on or off the hardware acceleration in Windows 11/10 using the guide, as mentioned above.

Should I disable hardware graphics acceleration?

It depends on the situation you are in. Hardware acceleration is supposed to help you get a better user experience. However, if you find any crash or lag issue while using a certain application on your computer, turning off the hardware acceleration might be handy for you.
