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?

Make sure you have your monitor plugged into the GPU, not the motherboard.

This kinda sounds like that

It's definitely plugged into the GPU. I've had plenty of opportunity to get acquainted with the back of my machine at this point. :,)

I just saw a meme about this, lol

Yup really does sound like that. I had a friend make this mistake when we upgraded some components in his computer last summer I asked him to plug everything back in...

In his case there wasn't a GPU on the CPU so the computer wasn't booting to any image.

We spent way too much time in the case second guessing my work only for me to go around to the back of the computer and facepalm.

Now i'm starting to doubt since this these responses have been so ubiquitous, but it's definitely not plugged into the motherboard's gpu slot. The motherboard has a single hdmi and displayport port. It, like all the other motherboard ports have a matte-black finish that matches the case. The displays are plugged into the glossy silver PCIE aligned hdmi and display ports, which doesn't match the rest of the case. The card is doublewide, occupying 2 pcie slots and is labeled "ASROCK".

I believe you've checked this correctly, but I want to clarify something: Even if the display is plugged into the graphics card, it's still possible that your CPU's integrated GPU (or even a CPU core) is being used for rendering, before sending the output to the display.

In other words, we've been asking where it's plugged in not because that would definitively pinpoint the problem, but because it could influence what's going on behind the scenes.

I hope System76 was able to help.

Gotcha, today is the first business day since filing my ticket. They've requested logs but no solutions yet.
