I mean I have a water-cooled Ryzen 9950X, Radeon 7900 XTX, 64 GB DDR5, 4 TB nvme, and 5120x1440 HDR monitor.
Plays borderlands 4, Rocket League, Horizon Zero Dawn, Horizon Forbidden West, Jedi survivor, elite dangerous, Sifu, star wars outlaws, god of war, cyber punk, and Elden Ring. And most of those run better for me on Linux than they did on Windows. For one, the various launchers(Ubisoft, epic, etc) actually stop when you stop playing the games, but fps is better too.
Have you had issues playing games on Linux? I can help if you need it. Highly recommend Nobara. It is based on fedora, a fairly well known and reliable version of Linux. The main difference is instead of the fedora kernel, it uses the kernel built by CachyOS. This optimized kernel results in roughly 10+ fps in games.
Idk why your switching off of Windows, but for me it is all the Microslop spyware they've been installing. Good God, I just installed Windows 11 home(instead of pro) on a PC for the first time and they literally showed ads during the installation. Plus the AI nonsense... ugh... Why do I need notepad to send my data to an AI? That's stupid, I want my data to be local and never leave my computer without my permission.
Regardless, good luck on your gaming journey! XD

I've been in a similar position to you. I was in an accident and woke up missing a quarter of my skull.
Props for getting back to servers and code as a part of your recovery. The recovery process for me took a long time and a lot of work. I imagine you are in a similar position and question whether things will ever be the same again, the same way I have. I don't know your particular situation very well, true. But for me, recovery not only took a lot of exercise, balance routines, relearning vocabulary, and a couple of surgeries; but it also took a lot of faith.
Shoot, you mentioned your projects, I did something similar. I found a hypervisor on Craigslist and set up Apache Cloudstack. I pushed myself to learn DevOps skills on it, Jenkins, terraform, cloud-init, and I'm still working on a AWS DevOps Cert.
But I would like to say kudos on your work. I think that doing it during your recovery is an extremely difficult prospect, but I do think that it pays off in the long run.
tldr; I think your recovery is coming along great. You may have quite the ways to go down that road, we don't really know. But until you're fully recovered, you will be in our hearts, minds, and prayers.
