Can it run ALL PC games? Honestly, no. But it runs way more than you might expect.
The Steam Deck OLED can run the vast majority of PC games. Most of your Steam library probably works. But there are exceptions, and knowing what those are saves you frustration.
Your Steam backlog: Seriously, most of it probably works. All those games you bought on sale and never played? Time to actually play them.
Indie games and older stuff: These run beautifully. Lower system requirements mean high frame rates and great battery life. Hades, Stardew Valley, Portal—butter smooth.
Modern AAA games: Elden Ring works. Baldur's Gate 3 works. Cyberpunk 2077 works. You might need to tweak settings and accept 30–40 FPS, but they're playable and enjoyable.
Emulation: Want to replay PS2 games? GameCube classics? The Deck handles retro gaming incredibly well. Some PS3 and Switch emulation works too.
Valorant: Nope. The anti-cheat refuses to run on anything but Windows. No workaround.
Destiny 2: Same deal. Bungie's anti-cheat won't cooperate.
Some competitive games: Various titles with aggressive anti-cheat protection just won't run on Linux. Check before you buy if this matters to you.
Here's my checklist:
Takes 30 seconds and saves you from buying something that won't run.
Don't expect PS5 performance. The Deck is a handheld—it's impressive for what it is, but it has limits.
Realistic expectations:
The OLED model performs noticeably better than the LCD version thanks to its more efficient processor. Same games, better battery life, sometimes a few more frames.
If there's a Windows-only game you absolutely must play, you CAN install Windows on the Steam Deck. It's not hard, but you lose some Deck-specific features and battery efficiency. Most people don't bother unless they have a specific game that requires it.
Think of Steam Deck compatibility like this: 85–90% of PC games work fine. Most of your library is probably playable. But that remaining 10–15%—usually competitive games with strict anti-cheat—just won't work without Windows.
If you're a PC gamer with a Steam library, most of it is now portable. If you're specifically looking to play Valorant or Destiny 2 on a handheld, the Steam Deck isn't your answer (yet, anyway).
