What is iGPU and why would I want to disable it?

iGPU stands for Integrated Graphics Processing Unit, a built-in graphics processor integrated into the central processing unit (CPU) of a computer. It’s designed to share system memory (RAM) to perform graphical tasks, which can be beneficial for low-to-medium graphics usage. However, if you have a dedicated graphics card, the iGPU can cause conflicts, reduce performance, and increase power consumption.

Disabling the iGPU can help solve these issues, as it allows your dedicated graphics card to take full control of graphics processing. This can lead to improved gaming performance, reduced power consumption, and even increased system stability. Additionally, disabling the iGPU can also help in certain scenarios where the integrated graphics are not compatible with specific software or hardware.

Will disabling iGPU affect my system’s performance?

Disabling the iGPU can have both positive and negative effects on your system’s performance, depending on your specific setup and usage.
