Not sure how Bottles and not buying games directly relate (other than Bottles also being able to play pirated games obviously), but anyway.
I switched to Linux on my main computer as a “New Year’s Resolution” and so far I’m not missing much. I did cross-grade from an RTX 3080 to a Radeon 7800 XT because 95 % of the problems I experienced were related to Nvidia and their crappy drivers, but after that I had little issues in general.
I also use Fedora + KDE. KDE on Wayland seems to be the most reliable way to get VRR (FreeSync) working with multiple monitors. I installed it onto a new SSD I bought for this purpose, but I’ll transition more and more SSDs over to the Linux install as time progresses. The only reason I booted into Windows again so far was to check out some application’s configuration so I could replicate it on Fedora’s side. I didn’t even bother to install the Radeon GPU driver under Windows.
I could complain about smaller issues, but these are mostly related to third party software where the Linux version has some weird quirks (or where there’s straight up no Linux version, mainly games).
Overall very solid and I assume it only gets better with time.
