Foundation: Setting Up Your Fedora System for Gaming

A solid foundation is paramount for any optimized system. For gaming, this begins with ensuring your Fedora installation is equipped with the necessary multimedia capabilities and up-to-date graphics drivers.

The Critical Role of RPM Fusion

The RPM Fusion repository is an indispensable resource for any Fedora user looking to unlock the full potential of their system, especially for multimedia and gaming. It provides a vast array of software that is not included in the default Fedora repositories due to licensing or patent concerns. For a gaming-centric setup, RPM Fusion is absolutely mandatory.

Enabling RPM Fusion Free and Nonfree

To begin, we must enable both the RPM Fusion Free and RPM Fusion Nonfree repositories. The Free repository contains open-source software, while the Nonfree repository houses proprietary drivers and software essential for many hardware configurations and multimedia codecs.

  1. Install the RPM Fusion Configuration Packages:

    sudo dnf install https://mirrors.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm https://mirrors.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm

    This command downloads and installs the release configuration files for both repositories, allowing your system to recognize and access their packages.

  2. Update Your System: After enabling the repositories, it is crucial to update your package list to include the newly available software.

    sudo dnf upgrade --refresh

    This ensures your system is aware of all available packages and their latest versions from all configured repositories.

Why RPM Fusion is Non-Negotiable for Gaming

RPM Fusion provides packages that are critical for modern gaming performance and compatibility. Without it, you would be missing out on essential components that directly impact your gaming experience, such as proprietary graphics drivers (if you opt for them, though we’ll focus on open-source for this guide) and a comprehensive suite of multimedia codecs.

The Power of Mesa Drivers

For users who prefer open-source solutions and are running AMD or Intel integrated graphics, the Mesa drivers are the cornerstone of graphical performance. Fedora typically ships with Mesa, but ensuring you have the latest, most optimized versions is key for gaming. RPM Fusion often provides more up-to-date Mesa packages than the default Fedora repositories, offering performance improvements and bug fixes that can directly translate to higher frame rates and smoother gameplay.

Ensuring Latest Mesa is Installed

While Fedora’s default Mesa drivers are generally excellent, you might want to ensure you are getting the absolute latest versions, especially if new game releases or driver optimizations are critical. RPM Fusion usually keeps these packages current.

sudo dnf install mesa-dri-drivers mesa-vulkan-drivers mesa-libGL mesa-libEGL

This command ensures you have the necessary components for OpenGL and Vulkan rendering, which are the primary graphics APIs used by most modern games. The mesa-vulkan-drivers package is particularly important for Vulkan-based games, which are becoming increasingly prevalent.

Essential Video Codecs for Multimedia

Beyond just rendering graphics, a good gaming system also needs to handle multimedia playback smoothly. This includes video playback for cutscenes, game trailers, and general desktop use. The video codecs often found in RPM Fusion’s Nonfree repository are vital for this.

Installing Essential Codecs

The gstreamer framework is widely used for multimedia playback. Installing the necessary GStreamer plugins ensures that your system can decode and encode a wide range of video and audio formats.

sudo dnf install gstreamer1-plugins-bad-freeworld gstreamer1-plugins-ugly-freeworld gstreamer1-plugins-good-extras gstreamer1-libav

These packages cover many common multimedia codecs, including those for H.264, H.265 (HEVC), VP9, and more. This is essential for enjoying in-game multimedia content without stuttering or format errors.

Enhancing Your Gaming Performance and Control

Once the foundational elements are in place, we move on to the tools that allow for fine-tuning and monitoring your gaming experience. These are the utilities that Bazzite often integrates, and which you can now add to your vanilla Fedora setup.

MangoHud: Your FPS Capping and Overlay Solution

MangoHud is an invaluable open-source utility that provides a comprehensive, customizable in-game overlay. Its most sought-after feature for many gamers is the ability to cap frame rates (FPS), preventing unnecessary GPU strain and potentially improving frame pacing. It also offers a wealth of other performance metrics, such as CPU and GPU usage, temperatures, and VRAM consumption.

Installing and Configuring MangoHud

MangoHud is readily available through RPM Fusion.

sudo dnf install mangohud

Once installed, you can launch a game with MangoHud by prefixing the game’s executable with mangohud. For example, if your game is launched via steam steam://rungameid/12345, you might launch it using a launcher that supports MangoHud or by configuring Steam’s launch options.

Achieving an FPS Cap with MangoHud

To cap your FPS, you’ll typically set an environment variable. This can be done directly in your terminal or, more conveniently, via Steam’s launch options.

To set an FPS limit of, say, 60 FPS, you would typically use:

MANGOHUD_FPS_LIMIT=60 mangohud <your_game_command>

In Steam, you can add MANGOHUD_FPS_LIMIT=60 %command% to the game’s launch options. This command tells MangoHud to limit the frame rate to 60 frames per second. Experimentation with different FPS limits is often necessary to find the sweet spot for your hardware and the specific game.

LACT: Unleashing AMD GPU Undervolting Capabilities

For AMD graphics card owners, LACT (Linux AMD GPU Overclocking Tool) is a powerful utility that allows for GPU undervolting and overclocking. Undervolting can significantly reduce power consumption and heat output from your GPU, often without a noticeable drop in performance, and sometimes even leading to higher sustained clock speeds due to better thermal headroom. This is a key feature for optimizing AMD GPUs, as mentioned in your requirements.

Installing LACT

LACT is typically available as a Flatpak, which simplifies installation and dependency management.

  1. Ensure Flatpak is Installed:

    sudo dnf install flatpak
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

    This command installs Flatpak and adds the Flathub repository, which is the primary source for many gaming-related applications.

  2. Install LACT from Flathub:

    flatpak install flathub com.gitlab.valhalla.lact

Using LACT for Undervolting

After installation, you can launch LACT from your application menu or via the terminal:

flatpak run com.gitlab.valhalla.lact

Within LACT, you will find controls to adjust various GPU parameters, including voltage and clock frequencies. The process of undervolting involves a gradual reduction of voltage while monitoring for instability. It’s a trial-and-error process, but the rewards in terms of thermal and power efficiency can be substantial. You’ll typically want to adjust the “Core Voltage” or similar setting downwards in small increments. Stress testing your GPU after each adjustment is crucial to ensure stability.

Proton Plus and Enhanced Proton Compatibility

When discussing gaming on Linux, Proton is the compatibility layer developed by Valve that allows Windows games to run on Linux through Steam. While Fedora ships with Steam, and Steam itself includes a version of Proton, you might be interested in features that offer more granular control or enhanced compatibility options, which is where tools like Proton Plus come into play.

Understanding Proton Plus (or similar tools)

Proton Plus is a graphical interface designed to manage different versions of Proton and apply custom configurations to them. It aims to simplify the process of using non-default Proton versions, such as those from specific forks or experimental builds, which can be beneficial for troubleshooting or improving performance in certain games.

While you might not need Proton Plus if you’re satisfied with the default Proton versions provided by Steam, it can be useful if you encounter specific games that perform better with a different Proton build. The benefit over “normal” Proton is the ease of switching and applying per-game settings without manually downloading and managing Proton versions.

Installing and Using Proton Plus

Proton Plus is also typically available as a Flatpak:

flatpak install flathub io.github.halide.ProtonPlus

Once installed, you can launch Proton Plus to manage your Proton installations. You can download different Proton versions directly through the application and assign them to specific games within your Steam library. This allows you to easily experiment with various Proton builds to find the best configuration for each game.

Advanced Tweaks and Additional Utilities

Beyond the core requirements, a few additional utilities and configurations can further enhance your gaming setup and provide deeper insights into your system’s performance.

Gamemode for Dynamic Performance Optimization

Gamemode is a daemon that optimizes your system for gaming by automatically adjusting various parameters when a game is launched. These adjustments can include CPU governor settings, I/O priority, process niceness, and more, all aimed at maximizing gaming performance.

Installing Gamemode

Gamemode is available in the RPM Fusion repositories.

sudo dnf install gamemode

How Gamemode Works

Once installed, Gamemode runs in the background. When you launch a game, the game’s executable can signal to Gamemode that it is running. Gamemode then applies a predefined set of optimizations. Many game launchers, including Steam, have built-in support for Gamemode.

To enable Gamemode for Steam games, you typically add gamemoderun %command% to the game’s launch options in Steam. This ensures that whenever the game starts, Gamemode is activated for it.

For advanced users, certain kernel parameters can be tuned to improve gaming performance, particularly for I/O operations and process scheduling. While Fedora’s defaults are generally good, specific tweaks can sometimes yield marginal improvements.

Understanding Kernel Tuning

This is a more advanced area and requires careful consideration. For instance, you might consider:

  • Swappiness: Reducing the tendency of the system to use swap space can be beneficial, especially if you have ample RAM.
  • I/O Scheduler: While less critical with modern NVMe drives, some users experiment with different I/O schedulers.

Modifying kernel parameters is done via /etc/sysctl.conf or by creating separate .conf files in /etc/sysctl.d/. It is crucial to back up any configuration files before making changes and to understand the potential impact of each parameter. For most users, the default settings are sufficient, but for those seeking every last bit of performance, this is an avenue to explore.

Shader Pre-caching with steam-permissions and enable-vulkan-pipeline-cache

While not a direct software installation in the same vein as the others, ensuring your system is set up to benefit from shader pre-caching is crucial for reducing stuttering in many games. This involves having the necessary permissions and enabling Vulkan pipeline caching.

Vulkan Pipeline Cache

Vulkan uses pipeline caches to store compiled shaders. This compilation process can sometimes be time-consuming and cause initial stuttering when a new shader is encountered for the first time. Steam and Proton can create and manage these caches.

The enable-vulkan-pipeline-cache option, often set via environment variables or within Steam’s launch options, can help manage this. You might see configurations like:

RADV_PERFTEST=ngcc,rt,shrd,hvl,pso %command%

While this example includes several RADV (AMD Vulkan driver) specific flags, the principle of optimizing shader handling is key. The exact method for enabling and managing Vulkan pipeline caches can evolve, but ensuring your graphics drivers are up-to-date and that Steam is configured appropriately for shader pre-caching is important.

Considerations for Other Gaming Platforms (Lutris, Heroic Games Launcher)

While Steam with Proton covers a significant portion of PC gaming, you might also play games from other platforms like GOG or Epic Games Store. For these, you’ll likely use launchers like Lutris or the Heroic Games Launcher.

Installing Lutris and Heroic

Both are available on Flathub:

flatpak install flathub net.lutris.Lutris
flatpak install flathub com.heroicgameslauncher.hgl

These launchers can also leverage Wine and Proton, and often benefit from the same underlying system configurations (RPM Fusion, Mesa drivers, codecs) that we’ve discussed. Some of these launchers also have their own specific performance tweaks or integration options that you can explore.

Bringing It All Together: A Streamlined Gaming Fedora

By meticulously installing and configuring these components on a fresh Fedora installation, you can effectively replicate the core gaming enhancements often found in curated distributions like Bazzite, while maintaining a minimalistic and direct relationship with your operating system.
