I really regret recycling my 32 inch Trinitron back in the mid-2000’s…

So I’m still using Windows on my desktop, but from my experience with Proton on Steam Deck, Proton works pretty flawlessly essentially translating the windows exe. I’m assuming it’s the same for a Linux desktop setup but I’ll let others who actually have experience here comment further. The only thing that you may have issues with are competitive online games, but those aren’t really my jam but understandable if they are for you.
