How can I tell if my GPU is being utilized properly? (self.linux_gaming)

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?

I have a 6800xt and can play literally all of them. There's no reason you shouldn't be able to.

Nooooo that would be a mistake with Linux.

KSP will run on a RPi. There's no reason you shouldn't be able to run the title screen. Something is very wrong.

My advice would be to contact System76.

Being that it's a pre built and preconfigured there's very little room for user error.

Did you enable Steam Play in Steam settings, under compatibility?

Yeah I've tried several Steam Play options. I get different behavior from crashing to some wonky rendering of the windows behind it, but none work

There's only one Steam Play option.

What do you mean? There are the following:

Proton experimental Steam Linux runtime 1.0 Legacy runtime 1.0 Proton hotfix Proton 9.0-4 ....

If you mean just the global checkbox, yes that's on

If you mean just the global checkbox

Yes, the option that says "Steam Play".

I don't think I have ever been GPU bound on KSP very well could be an issue with something else.
