Let alone MacOS, which is more supported than Linux but has comparatively much poorer hardware stats.
Graphics card driver issues largely stopped being a problem about 4 years ago, with both major graphics card manufacturers committing to open source drivers.
Packaging for multiple distributions is a problem that I would call "solved" for the past ~2 years, see my comment here: https://news.ycombinator.com/item?id=19844241
> To clarify, Easy Anti-Cheat still provides native Linux support and will continue to do so. Earlier comments by a partner reflect ordinary day-to-day prioritization decisions on anti-cheat issues across all platforms and not any change in long-term priority for Linux.

You never did give your graphics card model number, but according to this[1] page the Brazos platform had two codename variants for laptops and notebooks: Ontario and Zacate. Hondo and Desna were exclusively for tablets. There were no variants for desktops.
According to this page[2] that puts your card somewhere in the Radion HD 6xxx or HD7xxx driver set, and the only references to Ontario are the Radeon HD 6290 and the Radeon HD 7340.
If you go to the AMD drivers download page[3] you'll discover that both of these cards have dropped off the bottom of the list of supported cards in their respective driver categories.
Now hey, maybe your card is a slightly newer model and it's still in that download list. I don't know, since I don't know your exact card model. But my 10 seconds of research says that actually it's probably not supported any more. If I'm wrong about that then you're pretty god damn close to the cliff edge at this point.

The XML for the VM I configured in virt-manager can be found here:I don't think has any significant modifications. Eventually I want to switch over to using the newer q35 architecture. The only issues I've had with the VM are some audio glitches in some games and it has recently had issues with hugepages so I've had to disable that.
