If you are a Windows 10/11 user, you may have noticed that the Desktop Window Manager (DWM) process consumes a significant amount of GPU resources. This can cause high GPU usage and result in sluggish system performance. In this article, we will explain what DWM is, why it uses so much GPU, and most importantly, how to fix Desktop Window Manager high GPU usage in Windows 10/11.
What is Desktop Window Manager (DWM)?
Desktop Window Manager (DWM) is a feature introduced in Windows Vista that manages the graphical user interface (GUI) of the operating system. DWM uses DirectX to render the graphical elements of the desktop environment such as windows, menus, and buttons. It is responsible for applying visual effects like transparency, animations, and 3D effects.
Why does Desktop Window Manager use so much GPU?
DWM uses your computer’s GPU to render the graphical elements of the desktop environment. This can cause high GPU usage, which can result in slow system performance, particularly on older or less powerful hardware. Additionally, some Windows 10/11 users have reported that DWM consumes an excessive amount of GPU resources, causing their systems to lag and become unresponsive.
