I did test it myself yesterday on Live session through USB with the exact same edition and proton version and it worked just as normally but crashed 1 time and I also noticed sounds bug which I already reported to IA.
My specs during the test:
OS: Manjaro 21.2.2 XFCE edition (everything default, running as Live OS - without installing to disk)
CPU: Intel i5-3470
GPU: AMD RX 570 8GB
RAM: 16GB
On steam forums there was also someone on arch based distro with trouble running the CIU. I daily drive Linux Mint. Even have played few multiplayer sessions with IA without crashing so it may be hard to find the cause.
Thing is, it’s extremely unlikely that Valve would get to act on your report anytime soon, if at all.
And iA probably wouldn’t fancy fixing the CIU so that it works for every distro out there. There’s too many distros to be possibly fixing the game for every one of them. I tried Linux myself, a couple of times. I would switch over to it if it weren’t for the game compatibility issues.
My best suggestion is getting a Virtual Machine to play CIU on. If you don’t fancy switching OSes again that is.
IA already fixed the connection error under proton shortly after CIU got released on Steam. They don’t have to fix it for every distro, but just for Proton.
That’s why you don’t target just 1 distro but use something universal.
I daily drive Linux Mint since January 2021. I played 46 games on Steam during that year. Just 5 of them with Proton - everything else linux native.
Most games that don’t work currently are multiplayer and use some kind of anti cheat software that detects other OS than windows as cheating or have cutscenes using broken video format. If the game is singleplayer it has big chances of running successfully with Proton.
Oh fantastic suggestion. Let me waste space for virtual windows installation to play a game that weighs 400MB and while I’m at it let me pay $150 for the windows license for the OS since it is required to be legal.
I played CIU on Steam for 5.3 hours, played multi with IA. Never had a 1 crash. I don’t need to switch OS.
Hmm, this won’t be easy to solve. The crash is inside a DirectX function, and I don’t know how much the game can do about that. Also, the only Linux distribution officially supported by Steam is Ubuntu LTS (Steam Support :: Steam Client Troubleshooting on Linux), so… this might be unfixable.
Proton is easier, though as we can see it doesn’t always work for everyone.
That’s kind of very outdated and I don’t mean the Ubuntu LTS.
Valve had a falling with Ubuntu back in 2019 when the Canonical announced that they are dropping 32-bit support. Valve needed it for various things so they started looking for another OS. We already know that they settled on Arch + KDE combo for the SteamOS 3 and that they recommend Manjaro KDE until they release SOS3 in February along with Steam Deck.

That’s not to say debian distros won’t work with it. Since they do work.
So either WINE fault or Proton. I mean, it doesn’t hurt to report it to Valve. They said to report Proton errors on Steamworks forums
When SOS3 releases I’ll definitely be checking it out so I can test CIU while I’m at it.
Well, I got around the CreateDXGIFactory crash (by commenting it out), but it just crashed on D3D11CreateDevice. These are fundamental setup calls, so I think the underlying issue is that neither @Mikicrep 's setup nor mine support Vulkan, which seems to practically be a requirement for DirectX 11 emulation.
Well. The Live OS needs RAM so maybe that was the case, but it should still work pretty much like the normal installation.
Yeah, if you find any bugs share them mentioning what OS you use.
Can’t say for Mikicrep (and I imagine this solution isn’t as good as DirectX on Windows), but I didn’t noticed any lags at all. Works just as good as the normal one for me.
Not laggy that all, only problem is it crashes sometimes, but its good, u get ur lives return and somehow get 20x score u gained so far idk is it bug or good… But fps is 2x better than win
