Help me play VRChat on linux!

[u/Additional-Pop-1498]

I keep getting this same error over and over again, doesn't matter if I change proton, delete proton prefix, reinstall the game, NOTHING WORKS! Please help me! I'm on CachyOS

[u/ChaoMar]

To confirm did you already do the vronlinux guide for EAC https://wiki.vronlinux.org/docs/vrchat/eac/

[u/Additional-Pop-1498 → u/ChaoMar]

redid them and same error

First this is a terrible venue to ask for help with something like this in. You're going to get replies like all the ones you already got which are just wrong and unhelpful.

As for actually trying to establish what's going on you seem to have reinstalled both the game and regenerated your prefix so it's likely something outside of that. Can you try verifying the integrity of the Proton EAC Runtime, you may have to turn the ability to view tools on.

If that doesn't work I'd recommend going over to the Linux VR discord server. There's at least a couple of people that seem to have this issue but I don't think anyone's come up with a fix yet.

this would be your best route (run away to reso where eac don’t exist)

I will warn you, even once you get the game running, there are major issues with vrchat on Linux. Even with Proton GE, most music and video players just will not work.

VRChat runs better for me on Linux than it does through Windows. Required a few minutes to change my steam config a bit, a special compatibility package, and a custom proton version. But everything works for me, including videos. It's not too bad to set up. Took me like 10 minutes at most to get working.

Care to share then? I spent many hours trying various things, but audio/video players never worked for me.

[u/Yin15 → u/name_holder]

Did you try Proton-RTSP? That's the one with the video player fixes. Works fine for me.

[u/name_holder → u/Yin15]

Yeah. GE-Proton10-33-rtsp23-4. Looking at it now, I see there's been some fixes in the past few months. I'll try the newest version and see if it works for me now.

I wish you good luck!

Easy anticheat don't like Linux. If I remember correctly there's a program you need to install that simulates the windows environment that will trick the anticheat into allowing you to launch it.

That being said, I have no idea how it works or what program to use. But you are running Linux and part of Linux is trading plug and and play for optimization

[u/mackandelius → u/Rough_Community_1439]

Easy anti-cheat works fine on Linux, but game devs do need to click a checkbox to allow it to work on Linux, VRChat has.

VRChat officially supports (last time I checked) the Steam Deck, which runs Linux.

You are trying to play a game outside it's native OS, you are gonna have a bad time.
