Surprisingly, Valve rated Grand Theft Auto V Enhanced and Rainbow Six Siege as Steam Deck Playable

Even though both of them have anti-cheat that blocks Linux platforms from playing online, Valve have suddenly rated both Grand Theft Auto V Enhanced (and so GTA Online) and Rainbow Six Siege as Steam Deck Playable.

Many people have had issues with how Valve rate various games on Steam Deck, with a few outliers showing up as Verified when they don't perform well or Unsupported when they actually work fine. With the Steam Deck recently hitting 18,000 games playable / verified, Valve really need to ensure the system is working well to not give the wrong idea.

The new ratings now appear on the store pages for both games, which you can also see via SteamDB (GTAV / R6 Siege) showing testing was done and published.

And since the ratings are live on Steam, they then show as compatible when looking directly on Steam Deck too.

We know that Rockstar themselves intentionally blocked GTA Online for GTA V when they added in BattlEye. As they say clearly it's simply not supported on Steam Deck. Although single-player works, a Playable rating is very misleading.

For Rainbow Six Siege it has been blocked the entire time, although they did just launch a new update with additional anti-cheat measures.

Trying out Rainbow Six Siege on Desktop Linux and it clearly does not work when trying to join a match, getting kicked pretty rapidly before the game properly begins.

Trying to reconnect after this also does not work.

I then had to wait an hour before being able to test on Steam Deck, since it counted me as a leaver and locked me out. Same issue on Steam Deck though, it simply doesn't work. The live Playable rating from Valve is wrong.

Thankfully, Valve do have their two hour play time and two weeks refund period, but still — issues like this are not the best look for ongoing trust in Valve's Steam Deck verification system. Ideally, Valve should have some sort of manual rating lock on games that have these kinds of anti-cheat blockers, so they can't mistakenly get a rating that leads to player confusion. That way, if there's a legitimate change, Valve can get it checked properly first.

Especially important if Valve are going to continue with new Steam hardware based on Linux, as Valve did say "The future of hardware at Valve is bright" and noted 330 million hours were played on Steam Deck in 2024 so this trust in their system is vital.

I've reached out to Valve press about this and will update if any reply is received.
