Unfortunately the biggest issue now is the anticheats that only function on windows. My friends refuse to switch to Linux because you cannot play:
They'll play other games but because they mainline one of these they refuse to leave. As long as SteamOS has no answer to these anti cheats windows will maintain a dominance.

Technically, all the major anti cheats have Linux userspace binaries that even support wine/proton passthrough, so there are actually a lot of anti cheat games that run on linux as shown in the list.
The issue is not entirely something SteamOS can solve or is even linux's fault because no sane distro would ever support running a kernel level anticheat module. It would break the defining security features of linux, and I'm not even sure DKMS or Akmod would support it out of box on secure boot.
The games in question refuse to enable anticheat on linux because they know the userspace binaries are limited, but then their windows solution is just a crappy rootkit. It's not a very good or longterm solution either. EAC and Battleye both have demonstrable bypasses with various methods of fooling. Only Vangaurd seems to aggressively keep up with the arms race by literally scanning your PCIe devices for hardware cheats.
What they can do is to convince game OEMs to enable their linux AC support by marketing the potential customers they are losing out on. That's basically what happened with Halo MCC and Infinite. I'm still surprised they actually convinced Microsoft to allow both games to run on Linux with EAC.
I am an idiot, so this is probably a dumb question, but it sounds like you might be able to shine some light.
Why could we not run kernel level anticheat in a sandbox? Does kernel level inherently mean a sandbox cannot contain it?
As an aside is kernel level anticheat required for anti-cheat to function? Or are the developers of anti-cheat software just doing kernel level because its easier?
Fuck kernel-level anticheat.
I refuse to buy or play any games with Kernel Anti-cheat.
And I will die on that hill.
If it doesn't run on Linux because of intrusive anti-cheats you probably shouldn't install it anyway.
Congratulations? How does that help Linux adoption, though.
Well if they are losing out on sales due to practices that are incompatible with Linux then companies are less likely to use those practices in the future.
They literally care about market share and money watch the magical adoption of server stuff anti chest if Linux takes off
Don't make me tap the post title.
I'm sure it's on the roadmap, but not a current priority. First get it to work decently and iron all the kinks out of steamos, then they can look at anti-cheating.
Its not because steam doesnt support it. Some of the games on that list have banned players from connecting online from linux. Apex legends put out a newsletter about how they couldn't keep up with cheating using linux OSes and so they had to just cut it off entirely.
