Sorry for the late reply. I’m guessing: You look at general “utilization”.
- Win 11 Task Manager does not show CUDA usage by default.
- AFAIK the “utilization” does not take CUDA usage into account
- By default it gives summary view
So that we are speaking of the same measure:
-
Disable summary view: Right click GPU on the left.
-
Disable HW acceleration
- Now you can select CUDA to see actual utilization. IIRC stuff usually happens in cuda, copy 1 and copy 2, so select them from top left.
A better tool is nvidia-smi of course…
