How to disable Hardware Acceleration in Windows 10

In simple terms, the term 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. The idea is to speed up graphics performance and the rendering by moving it from the CPU to the GPU, 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. Turning off the Hardware Acceleration completely will run the application in software rendering mode’.

Before you proceed, you should know that not all computer systemss 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 onboard video.

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

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 0.


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.
