Disable Hardware Acceleration in Windows 10/8/7

02. December 2016 Hardware 0

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. 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 graphic 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 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’.
