A custom AMD GPU will power the Steam Deck, complete with eight RDNA 2 CUs, and up to 1.6 teraflops of performance. When you look at the hardware inside the Steam Deck, it’s even closer to a portable Xbox than you’d expect. That could mean titles like Apex Legends, Destiny 2, PUBG, Fortnite, and Gears 5 will soon work with Proton and the Steam Deck. “We’re working with BattlEye and Easy Anti-Cheat to get support for Proton ahead of launch,” says Valve. Proton does most of the work to make games run on the Steam Deck, but titles with anti-cheat software are still an issue on Linux. You can check to see if the games you play are supported over on Valve’s Steam site, or the Proton database. Installing Windows on the Steam Deck would open this device up to the thousands of games on Steam that aren’t listed as SteamOS compatible yet, and Microsoft’s Xbox Game Pass subscription. The Steam Deck ships with the Linux-based SteamOS.

That’s 7,586 games out of a possible 54,280 on Steam, compared to only 13 games on Steam that don’t work on Windows. While Linux support for gaming has been improving in recent years, particularly thanks to Valve’s Proton efforts, less than 15 percent of all games on Steam officially support Linux and SteamOS. The Steam Deck itself will ship with SteamOS, a custom Linux operating system that loads into the familiar Steam interface you’re used to on PC. “Steam Deck is a PC so you can install third-party software and operating systems,” says Valve, which means this hardware isn’t locked down in the way we’re used to seeing from tech companies. That means the Steam Deck could be the perfect Xbox portable, given Microsoft’s investment in shipping all of its future Xbox Game Studios titles on PC. The 7-inch device will play the latest AAA games, and because it’s a PC, you’ll even be able to install Windows on it. Valve just announced its new handheld Steam Deck, powered by a custom Linux operating system.
