JuxGD's Proton Package for Nix

Based on imaviso's dwproton-flake, this is a bit of an expansion including other useful Proton packages, including dw-proton, as well as support for non-flake based config. Use these packages in programs.steam.extraCompatPackages.

Also shoutout loplxl/GD-Low-Linux-Latency, that's basically the reason this repo exists.

Features

• Automatically tracks the latest releases of different Proton versions:

  • CachyOS Proton
  • DW-Proton
  • GE Proton

• Daily GitHub Actions workflow to check for updates

• Simple flake-based installation

Usage

NixOS

Flake-based config

Add the flake to your inputs and add the package to programs.steam.extraCompatPackages:

# only flake.nix example

{
  # ...
  
  inputs = {

    # ...

    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";

    proton.url = "github:JuxGD/proton-flake"

    # ...
  };

  outputs = { self, nixpkgs, proton, ... }:
  
  # ...
  
  {
    nixosConfigurations.yourhostname = nixpkgs.lib.nixosSystem { # replace `yourhostname` with your hostname ofc
      # ...

      system = "x86_64-linux";
      modules = [

        # ...

        ({ config, lib, pkgs, ... }: {
          programs.steam = {
            enable = true;
            extraCompatPackages = [
              proton.packages.${pkgs.stdenv.hostPlatform.system}.cachyos-proton # for cachyos proton
              proton.packages.${pkgs.stdenv.hostPlatform.system}.dw-proton # for dawnwine proton
              proton.packages.${pkgs.stdenv.hostPlatform.system}.ge-proton # for glorious eggroll proton
            ];
          };
        })
      ];
    };
  };
}

Without flakes

Haven't tried this pls tell me if it works lol

# configuration.nix

{ config, lib, pkgs, ... }:

let

# ...

  proton = import (builtins.fetchGit {
    url = "https://github.com/JuxGD/proton-nix";

    # important
    rev = "<hash>"
    # <hash> = any commit in this repo after 739a772111b0b97aab8143747f57d56743db5bfd
    # preferably the latest one since that's one that's the most updated
  });

# ...

in

{
  # ...

  programs.steam.extraCompatPackages = [
    proton.cachyos-proton
    proton.ge-proton
    proton.dw-proton

    # ...
  
  ];

  # ...

}
