The way Valve describes it, the new Steam Deck sounds like a tiny — but still alarmingly heavy — marvel, capable of running Steam’s vast library of games despite the beefy specs required to play many of them. However, it is at its core a Linux machine, and that may lead to some complications.

On its own, Linux is not the most video game-friendly operating system. To alleviate compatibility issues, Valve has built a feature called Proton into its Linux-based SteamOS. Proton is an amalgam of tools like Wine and DXVK that users would normally need to seek out themselves if they wanted to play a wider range of games on Linux. In short, it saves developers the trouble of porting their games to Linux, and it saves players the effort of figuring out how to make games work. Problem is, Proton isn’t flawless.

User-run Proton tracker ProtonDB (via PC Gamer) says that four of Steam’s ten most popular games — Destiny 2, Apex Legends, Rainbow Six Siege, and PlayerUnknown’s Battlegrounds — are “borked.” If you try to play them via Proton, they’ll appear to start up, only to crash, close, or fail not long after. According to user-submitted reports, this happens because those games’ anti-cheat systems don’t play nice with Proton, which leads to players getting insta-booted from multiplayer servers.

Fortunately, Valve is working on solving the problem.

“For Deck, we’re vastly improving Proton’s game compatibility and support for anti-cheat solutions by working directly with the vendors,” Valve wrote on the Steam Deck website.

Here’s hoping that it manages to balance out Proton’s protons and electrons before the Steam Deck launches in December. If not, my heart goes out to everybody who was hoping to farm engrams or pick up two different kinds of victory royale while on the toilet. The world mourns your loss.

That said, the Steam Deck is a fully functioning PC, so if you really want, you can always resort to a time-honoured Linux compatibility workaround: install Windows.


  • Whatever they are running internally, they seem pretty confident in order to release it later this year. I can’t imagine that would happen if anti-cheat didn’t work.
    I run Steam in Linux now. Stuff tends to work very well, and in some cases works better than Windows. Proton has improved at a very fast pace… just a few years ago I would never have imagined being able to play games like Cyberpunk 2077 on Linux (at launch no less!). I think people will be pleasantly surprised.

    • But with a graphics processor less powerful than the bog-standard PS4, ie. around a third as powerful as the PS4 Pro, and only 12% the performance of the latest Xbox, will we be able to play Cyberpunk etc in any meaningful way?

      (Steamdeck GPU – up to 1.6 TFLOPS, PS4 – 1.84 TFLOPS, PS4Pro -4.20 TFLOPS, PS5 – 10.28 TFLOPS, Xbox Series X – 12 TFLOPS)

  • If the Deck is as popular as the hype is, and meet even Gabe’s sales projections.
    I think we will find the barriers such as large install sizes, incompatible codes, netcode errors, etc will get fixed very quickly.
