To ensure games run well on Linux either via Native Linux builds or Windows games with Proton, part of the magic is in the Steam Linux Runtime. A new version of it, the Steam Linux Runtime 4.0 was recently put up with some pretty big changes.

What's the point of it? It ensures Steam and games run through Steam on Linux work properly across all the many different Linux distributions. Another secret Valve sauce for Linux. Well, not secret at all but you get my meaning I'm sure.

That's a good sign, that Valve is moving at least the runtimes to 64bit only. Maybe that means the client is under similar scrutiny internally. Recently when Fedora was discussing dropping more 32bit libraries Steam came up as a big issue.

Yeah, 32bit is why I removed Steam from my Debian desktop daily driver again. I got conflicting 32bit and 64bit versions of some libraries that broke my system. I'm going to try a gaming focussed distro like Bazzite next time.

Your better off using cachy if you want a gaming focused distro that doesn't break. Unless you use mostly flatpaks. Then bazzite is good

[–] Quazatron@lemmy.world 19 points 13 hours ago (2 children)

I just run Steam as a flatpak. Works fine.

[–] JustEnoughDucks@feddit.nl 3 points 3 hours ago

It doesn't work fine out of the box. I tried it on Opensuse MicroOS a year and a bit ago and had to search 3-5 pretty undocumented solutions to big problems before being able to play the same games that non-flatpak could.

Out of the box, proton didn't work at all.

Not sure why the downvotes. Flatpak is a great thing.

[–] Truscape@lemmy.blahaj.zone -3 points 12 hours ago

Unless you muck around in bottles a lot of things break.

[–] Mwa@thelemmy.club 7 points 14 hours ago

Give Steam Flatpak a try on Debian instead.

Didn't they already announce they're going to drop 32 bit?

[–] TheGrandNagus@lemmy.world 2 points 30 minutes ago

If you're talking about Fedora, no. One of the maintainers just proposed it and the media/commenters in the community went crazy without knowing the facts.

[–] wreckedcarzz@lemmy.world 3 points 15 hours ago

For windows at least, but I assume they'd do it across the board at once
