That sounds like a very specific user case, I’m using a laptop for teaching with a smallish screen so gnome actually improves my workflow and the visibility of the OS. I don’t need theming either. Gnome is really aimed at productivity imo.
I may need to try Zettlr out, something bugs me about Obsidian these days.
I only play older games, opensource games (like Pioneer Space Sim, Luanti), and emulate PS2 mostly (could do PS3/4 you bet) so AMD is fine for my use case and works out of the box. I know Nvidia Linux support has improved which means the latest graphics cards also pretty much work out of the box too. But by principle, I support AMD for the work they put into working on Linux.
Older graphics cards (like mine in a laptop bought in 2014) were not supported by Nvidia except through the open source one. So the performance would be sub par.
Started my EndeavoursOS gaming PC. Oh no, my new-Steam lists the game as windows only?
Proceeds to install proton and related software and bam, I can game.
I know it’s not Bazzite but there is sure as hell little reason not to use Linux any more except for enterprise computers and laptops.
