I wrote a follow-up on using my System76 Thelio Mira for gaming on Pop!_OS/COSMIC.
Main takeaway: Steam + Proton has crossed from “surprisingly good” to “boringly good” for the kinds of games I play. Most stuff just launches now, which still feels wild if you remember the old Linux gaming days.
The caveats are still real: anti-cheat remains the big wall, and I hit one weird COSMIC/Wayland fullscreen issue where games opened in the bottom-right corner until I fixed it with Super+F11.
Ryzen 9 9950X, 96GB RAM, RTX 5070 Ti. So yeah, if a game struggles here, I’m not blaming the CPU.
