I'll start with the AMD support one. AMDs drivers are already included in the linux kernel so you should be good to go. I've got hundreds of hours on my 7900XTX and things are running pretty smoothly.
Thanks for the confirmation.
I was perplexed by that part of the article, but no surprised, since the media keeps showing such ignorance about Linux and worse, AMD.
Given that the SteamDeck is an all AMD system and AMD works very closely with Valve and the Linux community, their hardware simply works out of the box, unlike the media favorite company, which is actually hostile towards open source.
I am currently using ChimeraOS and except for one small issue related to a Gigabyte bug, the experience is flawless.
Have you tried ChimeraOS and if yes, how would you compare it to Bazzite?
Sorry for the dumb question, but to be honest, this is the first time that I have heard of Bazzite.
