@Ariloum commented on GitHub (Apr 18, 2025):

I guess it's because my Perfomance Counters are disabled, I found that windows were abusing some of my SSD and was doing heavy writes with tons of gigabytes.. Thus I classified this as unwanted/bugged/sabotaged and triggered that off.

Why did nvitop needs these counters? I can see my GPU/CPU stats with CUDA/memory usage and so on in all other monitoring programs..

@Ariloum nvitop calls psutil APIs to retrieve system metrics. I think you should file this issue to psutil upstream instead.
