A Nix flake for CachyOS Proton, a compatibility tool for Steam Play based on Wine with additional patches and optimizations from CachyOS.

It is not affiliated with, officially connected to, or endorsed by Valve Corporation, CachyOS, or any of their subsidiaries or affiliates.

Usage

Add to your NixOS configuration:

{
  inputs = {
    nix-proton-cachyos.url = "github:kimjongbing/nix-proton-cachyos";
  };
}

Then add it to your Steam configuration:

# In your Steam configuration (e.g., configuration.nix or steam.nix)
programs.steam = {
  enable = true;
  extraCompatPackages = [
    inputs.nix-proton-cachyos.packages.${system}.proton-cachyos
  ];
};

After rebuilding your system, you should see something like "Proton-CachyOS" in Steam's compatibility tools list (Steam -> Settings -> Compatibility).

Credits

This package is just a Nix flake wrapper around:

• Proton-CachyOS by the CachyOS team - a fork of Proton with additional optimizations
• Proton by Valve Corporation - the original compatibility layer for Steam Play

All credit for the underlying software goes to their respective teams. This repository simply provides the Nix packaging to make it easier to use on NixOS.
