High GPU Usage on Windows 11

[CharlesMengCA]

NVIDIA 1650 Super

Same build of mpv, same version of video card driver (v566.36).

Windows 11 is using more GPU, could any one help?

Windows 10 22H2 - OS Build 19045.5371
Windows 11 24H2 - OS Build 26100.2894

Windows 10: around 4%

Windows 11: more than 20%

Other videos have similar problem.

Configuration working on Win 10

vo=gpu-next
hwdec=nvdec
gpu-api=vulkan
gpu-context=winvk

On Windows 11, I have to comment out gpu-context=winvk

Here is the gpu-debug output from Windows 11

output_w11.txt

If I use d3d11, even on Windows 10, the GPU usage will be high.

Could anyone help?

Maybe another reason to stay on Windows 10? :(

The resolution after scaling is different, you have to at least make sure that they are the same, so that the comparison is meaningful.

The scaling is not the problem. :) Here is the new screenshot on Windows 10
