Steam gaming on Chromebooks

Chrome OS 98 may offer a glimpse at Steam gaming on Chromebooks

The old “Chromebooks are just a browser” myth continues to die a slow death. After adding Android and Linux app support, the next big advancement for Google’s modern desktop platform is PC gaming. And I don’t mean PC game streaming, although that’s already available via Stadia and Nvidia’s GeForce Now. I mean a dedicated Linux container that locally adds Steam gaming on Chromebooks.

Google has been working on this project, known as Borealis, for at least a year at this point. And a new Chromium code commit found by Android Police suggests that Chrome OS 98 will show off the first glimpse of Steam gaming on Chromebooks through some experimental flags.

Based on the code, it appears that like Chrome OS itself, Borealis will have its own beta version. That suggests to me that it will also have a stable version as well, but I could be wrong. I could see value in having two versions so Google can get some field testing data on the beta version while having a usable method too. For now, the experimental flag will be chrome://flags#borealis-linux-mode. It’s not yet available in the Chrome OS 98 Dev Channel that I run.

One question I have is on the implementation side.

Steam Deck

Given that Valve has created Steam OS, which runs on Linux, for its Steam Deck handheld, will this Linux container be the same thing? In a way, I hope so, and not just because I reserved a Steam Deck. But rather, it would provide a consistent interface and experience across devices.

And another, more important question is, how will Steam gaming on Chromebooks run based on currently available hardware?

The newest Intel Core processors should be fine for the CPU side. Integrated graphics, though? That’s a constraint.

Chromebook myths on gaming

Note that the Steam Deck is using a custom AMD APU, which includes a Ryzen processor and a dedicated GPU. The GPU won’t rival the latest Nvidia and AMD graphics cards but based on game demos, it’s up to the task for 720p gaming with reasonable frame rates on most games. And I suspect that Steam gaming on Chromebooks will top out at 720p on pre-2020 devices.

Still, this is exciting news for Chromebook owners that are also PC gamers. And another reason that the “Chromebooks are just a browser” meme simply isn’t true and hasn’t been for years.

One thought on “Chrome OS 98 may offer a glimpse at Steam gaming on Chromebooks

  1. Borealis was originally supposed to launch in beta using the old Debian-based SteamOS in 2Q2021 and go into production with Chrome 96. I saw a scrum page to that effect but didn’t bookmark it and now couldn’t find it again if you paid me a million dollars. When Valve shifted SteamOS to Arch Linux, that forced Google to retool, and ship an entirely separate container instead.

    Incidentally Google added discrete GPU support (AMD and Intel GPUs only though, no Nvidia yet) to the ChromeOS kernel in 2020 as part of giving ChromeOS support for Intel Evo (then Athena) which included things like Thunderbolt4 support and support for kvm-qemu. The problem is that no one has taken advantage of this with hardware. A Mushu board consisting of a 10th gen Intel CPU and AMD dGPU has been around for awhile and has been used in Steam Borealis testing, and it was speculated that it would be used in the Pixelbook 2 that was supposed to arrive in 2020. But first there was the pandemic, then there was the component shortage and now Google plans a pivot (back) to ARM for ChromeOS so there will be no first party ChromeOS hardware from Google until 2023. As for the Mushu board, as Intel is now issuing 12th gen chips and will have 13th gen chips out a year from now, it has been appropriately scrapped. I haven’t heard anything about any other board with a dGPU.

    Incidentally, an AMD Zen 3 APU such as the AMD Ryzen 5 5600G would provide similar gaming performance to the Steam Deck. However, AMD isn’t making any effort to get ChromeOS manufacturers to use anything better than an AMD Ryzen 3.
