Valve's Steam Machine has plenty of critics, and for good reason. At $1,049 to start, it underperforms the PS5 in most scenarios. Yet as Grand Theft Auto 6 barrels toward its inevitable PC release, a question worth asking emerges: would Rockstar's monster crime sandbox actually run on Valve's compact gaming PC?
The answer is probably yes, though not without caveats.
The real bottleneck isn't hardware firepower. Rockstar's recent PC ports, particularly Red Dead Redemption 2 and the Enhanced Edition of GTA V, showcase how aggressively scalable modern games can be. Red Dead 2 packs so many graphics knobs and settings that Low Spec Gamer managed to get it running on a 2020 mobile processor at 20-30 fps. With FSR set to Performance and a mix of medium and high settings, the Steam Machine hits a solid 65 fps on the same title. GTA V Enhanced Edition pulls 60-70 fps on high settings with ray tracing enabled. GTA 6 will demand more, certainly, but the precedent for scaling across hardware tiers is well established.
Rockstar has also embraced the Vulkan engine, which helps spread performance across different platforms and operating systems. Where GTA 4 arrived on PC crippled by Games For Windows Live, modern Rockstar releases show a company that understands PC optimization.
But here's where things get messy: the PC version probably won't arrive until a year or more after console launch. Take Two CEO Strauss Zelnick signaled in a Bloomberg interview that Rockstar plans to focus on console players first, despite admitting that PC gaming can represent around 50 percent of a game's sales today. GTA V waited two years for its PC debut. Red Dead 2 endured a similar drought. The pattern is frustratingly familiar, though Zelnick's acknowledgment of PC's market size might shorten the next gap.
The deeper problem, though, isn't raw performance. It's anti-cheat.
GTA Online runs on BattlEye Anti-Cheat, which requires kernel-level access and doesn't cooperate with Linux. That's why GTA V displays an unsupported banner across Steam Deck and SteamOS machines. The single-player campaign works fine on Linux, but the multiplayer component remains locked out. Rockstar could engineer a workaround with its resources, but the company has shown little interest in satisfying niche audiences. Linux represents just 3.9 percent of Steam's user base, according to the latest hardware survey. That's unlikely to move the needle for Rockstar's decision-making.
So yes, the Steam Machine could probably run GTA 6's campaign with acceptable frame rates and slightly scaled-down visuals. What it almost certainly won't run is GTA Online, the living service component that Rockstar clearly intends to carry forward. That's not a hardware limitation. It's a business and engineering choice that puts SteamOS at a permanent disadvantage, no matter how capable the machine actually is.
Author Emily Chen: "The Steam Machine's real problem was never going to be graphics. It's the stubborn intersection of Rockstar's platform priorities and the murky world of anti-cheat on Linux, and that's a battle Valve probably can't win."
