GPU Load and Memory Load

Hello!

I use the “nvml” library and the “nvmlDeviceGetUtilizationRates” function, but I get the error “NVML_ERROR_NOT_SUPPORTED”, that is, my viewport does not support it. Although the utility “GPU-Z” shows “GPU Load” and “Memory Load”.

How does it get it or how can you calculate the “GPU Load” without using this function?
