sudo apt install nvidia-driver-550

# AMD (open-source Mesa — usually already installed)
sudo apt install mesa-vulkan-drivers libvulkan1 vulkan-tools

Enable Proton for Windows Games

In Steam: Settings → Compatibility → Enable Steam Play for all other titles and select the latest Proton version. Most Windows-only games now work out of the box.

Install Heroic Games Launcher (Epic / GOG)

# Download AppImage from heroicgameslauncher.com or via Flatpak
flatpak install flathub com.heroicgameslauncher.hgl

Performance Tweaks

# Install GameMode (reduces CPU throttling during games)
sudo apt install gamemode

# Run a game with GameMode
gamemoderun steam

# Set CPU governor to performance
sudo cpupower frequency-set -g performance

# Install MangoHud for in-game FPS overlay
sudo apt install mangohud
MANGOHUD=1 gamemoderun %command%  # in Steam launch options

Check Game Compatibility

Check ProtonDB to see community reports for any game’s compatibility on Linux. “Gold” or “Platinum” ratings mean the game works well out of the box.
