Unfortunately 'the majority of games' wont include whatever fotm rando game my friends are inviting me to this time. If gaming was strictly a solo activity for me I would have gotten rid of windows a long time ago.

Almost all the games I play are these random multiplayer games with friends. In my experience, proton is only a blocker around 5% of the time. I still have a windows partition for those times (and I always laugh when I boot it and am "welcomed" by their "Let's take a moment to configure windows" garbage).

Just saying, if you have the HDD space, I'd say give dual booting a shot. you'll probably be surprised how usable Linux is for gaming these days.

I hear you. Hopefully with the Deck getting more popular, developers will be forced to ensure compatability.

I've moved 95% of my gaming to Linux entirely, after the steam deck convinced me it had gotten this good, and I barely miss Windows. Occasionally I'll still boot over to Windows for something like iRacing or to just experience some of the better graphics features, but honestly I find I don't really miss them and the Linux gaming experience these days is pretty seamless, even with my wacky setup of i3 and nvidia.
