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?

Curious. Do you have a "run on discrete GPU" option when you right click an app icon?

Iirc that feature is exposed on GNOME. Maybe you couldn't steam on discrete GPU option as a troubleshooting step?

That said I use both AMD cpu and GPU and it correctly defaults to the discrete GPU so this may not be the case

Even the IGPU should get better performance than that. I played Kerbal Space Program on a 2011 MacBook Air and got at least 30 fps.

I don't appear to have this.

There's a program called amdgou_top you can use to see the breakdown of components on the GPU(s) and their utilization, as well as what apps are running on the GPU

which distro is it? there are many that were not made with gaming in mind

This is Pop_Os, which is System76's 'ubuntu like' distro that comes shipped with vendor maintained drivers. It comes preinstalled with steam and is intended to be able to use it right out of the box. I've opened a ticket with them to discuss it further

don't use it. It is totally left without support nowadays. They are developing COSMIC, a new Wayland desktop enviroment and Pop OS is abandoned. System 76 pcs support other distros too. You need something based on Fedora Atomic or Arch

My goal for this system was to eject windows from my life prior to the launch of Windows recall. That and host a bunch of docker containers in an environment more reliable than windows. I got impatient waiting for cosmic to reach full support, but still wanted to go with the distro system76 ships as "theirs" as opposed to putting Ubuntu on their hardware. I haven't checked if cosmic is officially out yet but will likely switch over when it is. I'm a novice with Linux btw. I can use it to host and run my software but wanted a prepackaged solution for my devbox so that I have a much lower chance of breaking it. Also things like my Wacom tablet just worked out of the box, which is all big plus.
