What are you talking about? Out of the 248 games in my Steam library, 190 of them are rated as working on Linux (Steam Deck Verified and Steam Deck Playable). 21 of them are untested, which means only 37 of them are rated as unplayable. Of those most are unplayable because they’re either VR games or they have restrictive anticheat. Some of them, like Medium, say they’re unplayable but work fine for me. I’m assuming that’s because the Steam Deck isn’t powerful enough to play Medium at more than 15 fps, but on my PC, it runs around 100 fps. Others, like GTA V, say they’re unplayable, even though I’ve fully played through them with no issue, even on the Steam Deck. I’m guessing that’s because GTA Online has anticheat, but I’ve played the single player and online and both have worked fine for me. (I just looked it up. They added BattleEye to GTA Online late last year, so yeah, GTA V is rated unplayable, even though the Story Mode is fully playable.)
I’ve even gotten games that refuse to work on Windows (like the original American Mcgee’s Alice and the original Journeyman Project) running great in Linux.
After running through a few of the untested games, some of them are untested, even though they have native Linux ports that run just fine. I’m assuming that’s because they haven’t been tested specifically on the Steam Deck.
Other than the ones with restrictive anticheat, everything I’ve tried from my Epic Games library works great too.
Of the games I play, almost none of them have worked worse on Linux than they do on Windows. Most work exactly the same, and a few work better. One (exactly one) has worked worse, for about a month, then a new version of Proton fixed the missing cutscenes.
I mean, Wine stands for “Wine Is Not an Emulator”.
