Gaming on AcreetionOS

Arch-based + current Mesa/NVIDIA drivers = one of the best gaming platforms around. Setup takes minutes.

Steam + Proton

sudo pacman -S steam lib32-mesa vulkan-radeon lib32-vulkan-radeon   # AMD
# NVIDIA instead: nvidia-utils lib32-nvidia-utils (see xref below)

In Steam: Settings → Compatibility → Enable Proton for all titles. Most single-player Windows titles now run out of the box — check specific titles on ProtonDB.

NVIDIA users: NVIDIA Drivers first; AMD users are already done (AMD & Intel Graphics).

Launch options worth knowing

gamemoderun %command%                    # performance mode while playing
mangohud gamemoderun %command%           # + overlay FPS monitor
PROTON_ENABLE_NVAPI=1 %command%          # DLSS on some titles (NVIDIA)

Install the helpers: sudo pacman -S gamemode mangohud.

Everything else via Lutris

Epic, GOG, EA, Battle.net, emulators — Lutris orchestrates Wine versions and runners:

lutris            # from repos/AUR; community install scripts handle the rest

Native games

Factorio, CS2, Dota 2, Hades, Baldur’s Gate 3…​ run native. Filter the Steam store by "SteamOS" — that flag means native Linux build available.

Anti-cheat honesty

Kernel-level anti-cheats (Valorant, some CoD/Fortnite modes) block Linux regardless of effort. Check https://areweanticheatyet.com before buying competitive titles. Single-player is unaffected.
