How can I tell if my GPU is being utilized properly? (programming.dev)

I purchased a system76 Thelio Mira Elite With a AMD Radeon RX 7900 XT. I kinda regret not going with Nvidia at this point but it is what it is. I primarily use it as a developer workstation, but want to play games on it as well so I can be rid of my windows box.

I didn't expect it to be able to play the latest and greatest games but I did expect it to be able to play older titles reasonably well. Games launch from steam and seem to work, but I'm getting between 0 and 10 fps on the title screen of Kerbal Space Program. Other games are similarly functional but poorly performing.

Where do I start? How can I ensure my GPU is being leveraged? Is this as good as it gets?

[ 5067.696] (II) Applying OutputClass "AMDgpu" to /dev/dri/card1

Make sure that you actually have permission to that /dev/dri/card1 device. This may be arranged by udev or "video" group membership.

Regarding AMD vs Nvidia, unless you need CUDA you probably made the right choice. This sounds like a config issue and you'd probably be dealing with the same thing with Nvidia too.

Yeah I'm pleasantly surprised by the unanimous responses that AMD seems to be the way to go in this space. At this point I know it's not using my GPU at all, so you are right that nvidia wouldn't be any different
