I am keenly interested in this thread/question as well, although I don’t personally have much to add, being only a sporadic user of Linux. In theory, I would expect Linux to be a friendly operating system for us, given that most components are open-source (granted, not all GPU drivers/blobs), there are several alternatives for window managers/compositors, and many settings can be tweaked. Disappointingly, it seems that several people have reported strain on Linux as well. Hopefully we can identify the safe versions/configurations/etc.
I could see myself using Linux as my main desktop OS someday, if safe for the eyes. Despite being a lifelong Mac user, per the info in other threads here, I sense modern macOS has become our adversary due to the inherent nature/design of its rendering pipeline. I can use Windows 10 at work, at least on my particular hardware (I know others here cannot), but I take exception to Microsoft’s cloud-centric vision for my user data so it will not be my primary OS for personal use.
