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?

    Do any of your underperforming games have a screen that shows which GPU they are using?

    I haven’t found any that do but I can try launching a few and searching.

    Take a look in each game’s graphics settings. Not all of them show it, but some do. In Baldur’s Gate 3, it’s shown in Options: Video: General: Display Adapter. In Elite Dangerous, it’s in Options: Graphics: Display: Adapter. There are other ways of trying to determine which GPU is likely to be used by default, but seeing it directly in-game is the best way to be sure.

    Does an overlay appear in the top left of the screen if you put DXVK_HUD=devinfo %command% in an underperforming game’s Steam Launch Options?

    For the 3 I’ve checked so far no, I don’t see that.

    The fact that you see no DXVK overlay when using that launch option suggests that either none of the games you tried use DirectX 9/10/11, or there’s something missing/misconfigured/old in your Vulkan driver stack. I would expect System76 to be able to help with this more efficiently than we can, since they sold you the system for use with Linux and are known for being competent.

    EDIT: I just noticed your other comment that shows Pop!_OS 22.04 LTS as your Linux distro. That release predates your GPU model by about a year, I think. It seems likely that you just need to get a newer kernel, firmware, and graphics drivers installed. This stuff is available upstream of your distro, so it shouldn’t be too hard for someone who knows Pop!_OS well, like System76. :)

      Yeah, that’s a good point, but:

      1. It sounds like he bought a system with the GPU in there, and that it came with the distro pre-installed. I’m skeptical that System76 is gonna ship something without the software in place.

      2. It’s an LTS release. I think that the way Ubuntu works – and presumably PopOS, though I’ve never used it – is that with LTS releases, they only do a major release every couple of years, but do push out updates for time-sensitive software like video drivers that require updates. If this were, like, the regular Ubuntu release, which has a six month release cycle, then I’d agree.

      So I’d guess that the most-likely scenario is that whenever he bought the hardware, there was support in the OS, and they shipped the box with the current LTS release and with the necessary updates. That’s just a guess.

      Like, when I said “you probably need newer drivers”, I was thinking that he was using some really elderly distro and just hadn’t ever updated it or something.

        I would have expected System76 to ship it with all the necessary updates for the GPU, too, yet we haven’t seen any evidence of it, and we are seeing behavior consistent with it not being done. Maybe a human made a mistake somewhere along the line.

      KK will do.

      I will certainly reach out to them, but it hadn’t occurred to me until this post ¯_(ツ)_/¯

        BTW, I edited my comments; you might want to re-read them if you didn’t catch the edits.

        Don’t worry. This seems more like a software setup problem than faulty or weak hardware.

        Good luck!
