Looks like Linux gaming may get yet another boost, thanks to Google? Yes. Backing up previous information on Steam support coming to Chrome OS it looks like the project is still going.
This isn't some kind of wild rumour either, given the previous info with Google's own Kan Liu confirming their plans. This time the report comes from 9to5Google, which points out something being worked on called "Borealis" which appears to be a kind of Virtual Machine with a full copy of Ubuntu and Steam pre-installed and ready to go. It's interesting as they already had Crostini with Debian but it appears they're going a different way for Steam.
While Google now have Stadia to bring gaming to almost any device out there, they of course want more to people to buy their own devices with Chrome OS and enabling more gaming is a big way to push them. This is where Steam comes in, since it already supports Linux and Chrome OS is built from Linux.
Chromebooks are steadily getting more powerful too, as they bring in newer generation Intel processors that can handle a bit of a load and it appears AMD Ryzen Chromebooks will also enter the scene soon. So with Steam on Linux and more powerful internals, things are aligning for more serious gaming on Chrome OS.
Since Chromebooks are incredibly popular devices, being able to tap into another big market would be a welcome boon for Linux gaming as a whole.
