Introduction

These notes and tips describe how to run Battlefield 2 on Linux using Wine/Proton.

Lutris is a recommended launcher for managing games on Linux. It allows users to organize games and software, select different Wine or Proton versions, apply graphics wrappers, and configure libraries as needed. Unlike automated tools, Lutris provides flexibility by leaving configuration choices to the user.

Lutris offers flexibility in choosing libraries and configurations for each game and software.
Not all setups work out-of-the-box; some trial and error may be required.
Documenting setup choices (Wine/Proton version, DXVK settings, etc.) helps with replication and troubleshooting.

Some assumptions are made to keep the documentation concise. Additional details and tool-specific instructions may be added over time to improve coverage.

Tools & Setup

Wine/Proton: Essential for running Windows-based games on Linux.
Lutris: A versatile game launcher that allows you to:
- Organize all your games in one place.
- Choose specific Wine or Proton versions per game.
- Apply different graphics wrappers and libraries.
- Maintain control over configurations rather than relying on automation.
DXVK: A graphics wrapper that translates DirectX calls to Vulkan, improving performance on Linux.
OpenAL Soft: An open-source implementation of the OpenAL 3D audio API.
- Provides better audio compatibility for older games.
- Often required to fix missing or distorted sound.

You need a copy of the game of course, the game is abandonware so you can find it easily on Internet

Runtime Environment

Wine version: wine-proton-9.0-1-amd64
Prefix architecture: 64-bit
DXVK Version: 2.6.2

Installation Steps

Install Lutris

There are several ways to install Lutris. Visit the official download page and choose the package that best fits your system.

Always keep Lutris itself updated, but avoid blindly updating other libraries (such as DXVK) unless you encounter issues. Each game or software setup may require specific versions of these libraries, so it’s best to leave working configurations untouched.

If you experience problems, try newer versions of Wine/Proton or DXVK, but remember: stability is more important than always having the latest release.

Install Wine

There are many variations of Wine (Proton is a specific version of Wine for Steam games), you can install multiple versions on your system so feel free to try the one that works for you.

Wine builds from Kron4ek can be found on his GitHub page.

A version confirmed to work well with Battlefield 2 is wine-proton-9.0-1-amd64.

You can easily install different versions with ProtonUp-Qt, for Steam OS users, there is a flatpak version.

Setup Lutris Environment

A new Wine environment should be created to install the game. Installing multiple games in the same Wine prefix can lead to compatibility issues, as each title may require a different version of Wine or Proton. Creating a separate environment for each game or software is recommended to ensure stability and easier troubleshooting.

1. Click the + icon

in the top-left corner, then select Add locally installed game. We won’t use any scripts; everything will be configured manually.

Manually configure a game since we need to install it the traditional way

2. In Game Info

specify Wine as the Runner. Filling in the remaining fields is optional, except for the Name.

Select the Runner as Wine

3. In Game Options

set the Wine prefix to the folder where Wine will create the environment for this game. It is important to select a different folder for each game or software.

The Executable and Arguments fields are used after installation, when the game folder is ready. At that point, you can set bf2.exe as the executable. For now, leave these fields empty.

Keep the Prefix architecture set to Auto (a 64-bit prefix will be created).

4. In Runner Options

choose the Wine version. If you have already downloaded the correct Wine build, select it here. Avoid choosing random versions — always take notes on which version you are using. See the Install Wine section for recommendations.

One important graphics setting is the DXVK version, which can significantly improve performance. I currently use version 2.6.2. Keep an eye on updates, as newer releases often enhance performance and fix graphical issues.

Leave DLL overrides empty for this game, since there are no DLLs in the game folder that need to replace Windows library counterparts.

5. In System Options

you can add environment variables to help with logging and performance:#DXVK_FRAME_RATE – limits the frame rate

DXVK_HUD – displays system specs and an FPS counter
ALSOFT_LOGFILE and ALSOFT_LOGLEVEL – enable logging for the OpenAL Soft library

After saving, you will have created the game profile. To generate the actual Wine prefix, trigger the Wine executable by clicking the arrow icon at the bottom of the application and selecting Wine configuration. After a few seconds, the Wine configuration window will open. You don’t need to change anything here, just close it. The Wine prefix folder will now be created, containing all necessary files. Think of it as a portable Windows installation where you can install the game.

Install Battlefield 2

The recommended version is the Complete Collection with all expansions. The game requires a valid CD key; utilities such as BF2KeyMan can generate keys and apply them to the Windows registry.

After mounting the disk of the game (search mount on Internet), you can run the setup by clicking Run EXE inside Wine prefix.

The setup should complete with no issues, next step is to update the game with the few patches released. You need two patches, BF2_Patch_1.41.exe and BF2_Patch_1.50.exe. Install them following the same process you did with the game setup.

If you don't have your own copy of the game you can use random CD keys to install the game and expansion, by using a neat application BF2KeyMan.exe you can generate keys for the game and apply them to the Windows registry with a few clicks.

Restore EAX with OpenAL Soft

The game supports EAX. To enable audio hardware capabilities, OpenAL Soft can be used to replace the existing library. The setup is straightforward and works well with many games, not only Battlefield 2. The first step is to determine whether the game uses the dsound or openal audio library. In the game folder, you will find a library called BF2OpenAL.dll. From the name alone, you can tell that the game supports OpenAL, so we will use OpenAL Soft to replace it and enable EAX support.

Download OpenAL Soft from the GitHub release page. The version I currently use for this game is 1.23.1, which I recommend for this tutorial. After extracting the archive, you will need two files:

From the router/Win32 folder, take OpenAL32.dll. Rename this file to BF2OpenAL.dll and replace the existing one in the game folder.
From the bin/Win32 folder, copy soft_oal.dll into the game folder.

Next, download the OpenAL configuration for UT2004 from GitHub. We will use part of its content. Specifically, you need the file OpenAL-44100Hz.zip, which contains alsoft.ini and a folder with HRTF profiles for 3D spatial sound. Extract the archive and place both alsoft.ini and the OpenAL folder into the AppData/Roaming directory of your prefix.

The default configuration should work fine, but if you want to change the profile, you can edit the alsoft.ini file and modify the default-hrtf property. You can experiment with different profiles and see which works best for you by using the RightMark3DSound software. After placing the profiles in the Roaming folder, simply edit alsoft.ini and run the software to test how the audio sounds in your setup.

Setup Punkbuster

PunkBuster is required for multiplayer on certain servers. The appropriate version must match the server configuration. Archived instructions are available on the official site.

Tips

How to enable VSYNC

Created a file dxvk.conf in the game folder with the following content:

d3d9.presentInterval = 1

How to limit FPS

To limit FPS, set the environment variable:

DXVK_FRAME_RATE=60

(Replace `60` with your preferred frame rate.)

Game Start Arguments

The following arguments can be used to launch Battlefield 2:

+fullscreen 1 +szx 1024 +szy 768 +menu 1 +modPath mods/AIX2

+fullscreen 1 — enables fullscreen mode.
+szx 1024 — sets the screen width to 1024 pixels.
+szy 768 — sets the screen height to 768 pixels.
+menu 1 — starts the game with the menu enabled.
+modPath mods/AIX2 — specifies the mod to load. The value must match the exact folder name inside the `mods` directory. If omitted, the game launches in vanilla mode.

Troubleshooting

If the game does not launch, switching Proton versions may resolve the issue.
Graphics issues can be diagnosed using DXVK logs.
Multiplayer problems may require verifying PunkBuster setup.
