Know Everything about: Hardware Acceleration in Windows 10

What is hardware acceleration? How to enable/disable hardware acceleration in Windows 10? Is there a great hardware-acceleration video transcoder to speed up video transcoding on Windows 10? In this article, we would like to discuss hardware acceleration in Windows 10, including its definition, why and how to enable/disable it in Windows 10, and hardware-accelerated video transcoder which can greatly speed up video encoding/decoding speed.

What is hardware acceleration in Windows 10?

In simple terms, the term Hardware Acceleration means using computer’s hardware for performing a certain task and function faster than would be possible using a software. The hardware able to perform acceleration process is called hardware accelerators. GPU is an example of hardware accelerator which can offload the task from CPU to lead a faster and steadier playback of videos and games. Sound card is another example to deliver higher-quality sound playback and recording. Instead of handling anything with CPU, hardware accelerators take over specific tasks with greatly improved execution.

Why and How to Enable/Disable Hardware Acceleration in Windows 10?

To utilize hardware acceleration, the performance of an application can be significantly improved if you have a strong GPU. In addition, video encoding/decoding, editing/rendering will be greatly speeded up on a computer with CPU including Intel QSV or graphic card featuring Nvidia NVENC.

On the other hand, hardware acceleration turns to be inactive when the computer is armed with a powerful processor but weak components. Also, some problems may happen due to the use of hardware acceleration. For example, you’d better disable hardware acceleration in Chrome to fix black screen issue when playing a video.

In the following, we will lead you to enable/disable hardware acceleration in Windows 10.

The Hardware Acceleration tab in Windows allows you to specify the performance of the graphics hardware present on your PC. To disable or reduce Hardware Acceleration in Windows 10/8/7, 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 the Graphics Properties box. Now open ‘Troubleshoot’ tab. If your current display driver does not allow you to change the settings, you will see the Change settings button grayed out, and you will not be able to change the settings.


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.


Tip: If you find that the option is grayed out, check if your hardware permits it and ensure that you have updated drivers.
