I just keep all my actual stuff in a separate /stuff partition, so my home folder is only config files. Then I use NixOS home-manager and Impermanence to manage the dotfiles.
Yeah, I use NixOS so my whole system is defined in a couple config files, so when reinstalling I can just point the installer at my config and get (pretty much) the exact same system. Same packages, git config, aliases, package versions, firewall rules, kernel version, etc, only thing missing is a couple dotfiles I haven't switched over yet but those are synced using Syncthing anyways.
I used the Sweet-KDE color scheme for years on KDE Plasma, but recently I've been converting everything to Catppuccin Macchiato. Default icons and cursors.
Using a 6650 xt and FSR balanced to play Baldur's Gate 3 at 4K looked pretty good on a 4K TV, although a monitor is gonna be closer to your face and you're gonna need more vram if you're playing those really new AAA games at 4k and 1440p.
Wayland all the way, 120 hz Freesync monitor with 60 hz second monitor works perfectly on KDE Plasma with AMD. No fussing about with X11 configs or worrying about if the compositor is active or not, it just works.
Yep, tried a couple distros out and ended up on Arch for a year and was happy. Then switched over to NixOS and have been using it ever since, there's no way I could ever main any other distro.
Weird, for me that only pops up if I already have the app installed, and only when I navigate from a different website to that one. I'm using Firefox Beta if that matters.
You can use Gamescope or I think Proton/DXVK has FSR1 support as well
