Title, I am unsure if games are using my GPU or if using my CPU, or maybe my GPU through my CPU, I do not know, something is using my GPU, but I think its just KDE plasma, and I would like to know definitively how to find out
Everyone talking about nvidia, but install radeontop for amd cards. It’s not very detailed but shows the gpu usage.
For nvidia I like nvidia-smi.
nvtop, while it sounds like it’s nvidia, is brand agnostic It actually stands for “neat videocard top”
It’ll show per process usage of memory and compute usage on most GPUs
unfortunately, radontop doesn’t support relatively old cards. I get this error. (And the github page states that >R600 will work)
Unknown Radeon card. <= R500 won't work, new cards might.Also, my AMD CPU has a integrated GPU too, radeontop just doesn’t know about it.
The GPU works on my system tho, just radeontop doesn’t detect/support them. Oh well.
That’s a bummer then. Sorry friend.
Since you’re on KDE, plasma-systemmonitor should already be installed. It is the closest to the Windows task manager that you’re probably familiar with.
If you’ve got an nvidia gpu+drivers installed, you’ve probably got ‘nvidia-smi’ already which will show you utilization and which processes are using it.
