I'm going to go against the grain and say it's their VR hardware they've been sitting on for years now.
Steam Frame, and then calling glasses "frames" is common.
Either case it seems like a bad name, but I'd reckon it's their VR/AR device.
Edit: also to add they've been working a lot on Proton for ARM as of late, as well as proton in general which they initially set out Proton as being a universal translation layer, not just x86-64.
Might catch flak for this, but Starfield.
I just wanted something mindless where I could mix FPS with base building and RPG elements. I know there's Fallout 4, but I want my bases looking nice. Starfield isn't exactly the best for looks either, but it's the best I have in my library for these aforementioned things. I'm open to suggestions, but until then I'm just going to randomly kill things on Starfield.
For the loooonnnnngest time, I had issues running VR on Linux. And for a few years when I started off (many years ago), most games wouldn't run. Things have changed since then however. Now I'm finding all the desktop/handheld based games I want to play; I can just play. In addition, the issues I've constantly had with VR now have been alleviated (albeit with some manual tinkering).
Desktop games without anticheat will just work 99/100. VR takes some effort to work, but is worth it. VR on Linux still isn't exactly perfect either. You sometimes press something in a game, the screen will freeze and you can see/feel it for sure. But, that happens maybe once every 10 mins or so, so it's workable since all I use VR for is VRChat anyway.
Life's good on Linux now. Besides college, I don't think I'll be needing to switch to Windows at all anymore.
Oh, actually, now that I remember. I run World of Warcraft through bottles. Every so often WoW updates and kills functionality. I have to rebuild my Bottle, shift my files over and then it runs again, but that's also outside of what Steam does, so.
Besides all of the above, I think I can stick full time to Linux now.
It feels wonderful having an operating system that doesn't own you anymore.
I'll check out some gameplay footage of it later today. Thanks for the suggestion.
Cheers!
