No need to apoligise! I get that you're frustrated and why. AMD is really not (yet?) anywhere close to Nvidia for AI (or Ray Tracing!).

Compared to what you documented in your blog?

Yes. What I documented on the blog is a few commands once in a lifetime, from the comfort of your GUI, with the browser running where you can copy-paste from directly into the terminal emulator. I do consider that a lot less faff than booting off a live USB and figuring out how to compile a driver that DKMS failed to do automatically, then make sure it will work when I boot from my actual system.

Not to mention the rescue CD is if DKMS fails, your steps are just to get it working.

Not quite. The system works fine without that. In fact, I played a few games with no issues whatsoever before I figured out there were firmware files missing. In fact, the only thing that tipped me to thag were errors in dmesg which I only looked because I'm a stickler for that kind of stuff and decided to poke and prod as many logs as I could when I was building the system.

Also like I mentioned, this is only necessary because Debian haven't packaged those files yet. Many distros have them out of the box.

In any case, I know that plenty of people run Nvidia on Linux and face no issues. I have no interest in AI stuff on my Linux box and I have no love lost for Nvidia. That, coupled with AMD having been historically a lot friendlier to Linux than Nvidia, plus the fact that the drivers compile and ship with the kernel, made my purchase decision pretty easy. To each their own though, and clearly for your needs Nvidia is the way to go.
