Hello iTsnotCaSe,
Welcome to Microsoft Community.
Desktop Window Manager or DWM.exe is the system manager that generates every element visible on a PC/laptop. In addition, it is responsible for stimulating all visual effects in Windows menus, transparent components, wallpapers, themes, thumbnails and system animations. The built-in graphics card is often used by desktop window managers for all needs.
Here is a list of the most common causes:
The hardware-accelerated GPU plan is enabled.
The Windows version is outdated. (The odds are low.)
The graphics driver is corrupt or outdated.
Corrupted/corrupted system file.
The Settings in the NVIDIAControl panel are incorrect.
Even when the PC/ laptop is inactive, users report seeing GPU consumption of over 70%, which is not normal. DWMS typically use Gpus of 1% to 3% of total volume.
Therefore, the following suggestions may solve this problem:
- Keep your Windows operating system updated.
- Disable visual effects in Windows appearance and performance.
- Switch the Desktop Window Manager task level to Efficiency Mode.
- Disable GPU scheduling for GPU hardware acceleration.
- Update your video card driver.
If anything is unclear, please do not hesitate to let me know.
