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?

It doesn’t appear to be set

Ah, okay. Bit of a long shot.

and additionally I don’t appear to have the libgl1-mesa-swx11 package mentioned in that post.

You shouldn't need it -- that's for software rendering.

You might want libgl1-mesa-glx, but it sounds from that page like that was restructured prior to your distro release.

https://askubuntu.com/questions/1517352/issues-installing-libgl1-mesa-glx

ibgl1-mesa-glx has been a transitional package for a while and is now obsolete from Ubuntu 23.10 and onwards.

Installing libgl1 and libglx-mesa0 instead of libgl1-mesa-glx will result in equivalent behaviour and should work on Ubuntu 18.04 and newer.

Both libgl1:amd64 and libglx-mesa-0:amd64 are installed on my system. Are they installed on yours? If not, if they are available in your apt repo, maybe do so and see if your problems disappear?
