So I was playing Cities Skylines and opened up MSI Afterburner to check FPS, utilization, temps, etc. I was getting 20-30 FPS, on a brand new PC (that I built) on low settings. My CPU and GPU usage were very low, and so were their temps. Can anyone explain this? Why is my CPU and GPU only getting 20-30% utilization at 40 degrees? This could be an incredibly stupid question, but I'm new to this.

(I know these are odd system specs, but some of the components were all I could find due to Coronavirus)
