I game on linux regularly, primarily thanks to Valve. In the last 2 months steam lists 11 different games I've "Played Recently".

• 7 worked flawlessly (Baldur's Gate 3, Destroy All Humans!, Divinity: Original Sin 2, Besiege, Deep Rock Galactic, Shotgun King, Call of Cthulhu)
• 1 the native linux version doesn't work, but the windows version works perfectly (Northgard)
• 1 didn't initially work, but worked a month later after proton was updated. (Grounded)
• 1 I had to choose an older version of Proton (due to the external launcher breaking things), but with enough performance hitching during cutscenes that I chose to just play it on windows (Star Wars Jedi: Fallen Order)
• 1 I couldn't get to work, but I honestly don't know if it's a linux issue because the game's discussion forums are full of people saying the game is riddled with game breaking bugs on windows (The Sinking City)

I've been gaming on linux for a couple of years now, over that time I've put many hours into WoW, Sea of Thieves, Rimworld, Golf with your Friends, Core Keeper, Outer Wilds, and dozens more without any issues at all. 90%+ of the time the game starts up and just works.

I'm just one datapoint, but yeah, Linux as a gaming platform is totally viable for me these days.

Also, protondb lists 19% Verified and 16% Playable, so your 5% number is just demonstrably wrong.

Cheers.

If you consider only about 5% of Steam games being Linux-friendly these days

No matter how you twist and turn things, this is just flat out wrong..

Survey says...No.

The only games that don't work are essentially the ones using DRM/anticheat implementations that don't support multiple platforms. Meaning more like 75% of all Windows titles work under Linux just fine.

Again, this community is delusional lol. If you consider only about 5% of Steam games being Linux-friendly these days as “a non issue nowadays,” I’d hate to see your game library.

Speaking of delusional. You don't seem to have a whole lot of ideas about Linux gaming if you truly believe this ignorant nonsense.

79% of my library has a Silver or higher rating on ProtonDB, 65% are Gold or Platinum rated. For the Top 100 in Steam it's even better with 89% Silver+ and 79% Gold+. Of the Top 1000 Steam games it is 87% Silver+ and 75% Gold+. Even if we look at the entire Steam catalog we have 13% & 11% respectively, and that's only so low because there's literally just no reports. Only 1% of the titles are considered to be "Borked", another 1% are Bronze rated.

And again, that's just Steam and what has been tested by people. Most titles just run, others require minimal tweaking, some require a little tinkering.

Most of what you are missing out on are games that require some form of anti cheat. Most other stuff just runs. Most new triple A games just run these days.
