Gaming

The gaming group sets up Steam and everything around it. Install it with the rest, or later with ./install.sh --groups gaming --only packages,system.

What you get

Tool	What it's for
Steam + Proton	Steam games, Windows ones included
ProtonUp-Qt	installs Proton-GE (fixes many games Valve's Proton doesn't)
Heroic	Epic Games and GOG
Lutris	everything else: Battle.net, EA, emulators, Windows installers
Wine-staging, winetricks, protontricks	running and patching Windows games outside Steam
GameMode	CPU governor, GPU clocks and priority boost while a game runs
MangoHud	FPS, frame time, CPU/GPU load and temperatures over the game
GOverlay	GUI for MangoHud settings
gamescope	Valve's micro-compositor: fixes resolution, scaling and frame pacing
game-devices-udev	Xbox, PlayStation, Switch and 8BitDo controllers work without root

You are added to the gamemode group, and the GPU module installs the 32-bit Vulkan driver Steam needs.

Steam launch options

Right-click a game → Properties → Launch options:

mangohud gamemoderun %command%

If a game has the wrong resolution, scaling or stutters, run it through gamescope at the panel's native size:

gamescope -W 2560 -H 1600 -f -- mangohud gamemoderun %command%

The MangoHud overlay toggles with Right Shift + F12; its look lives in ~/.config/MangoHud/MangoHud.conf.

What Hyprland does for games

• Tearing for the lowest input lag: Steam games (steam_app_*), gamescope and any window that declares game content get the immediate rule (hypr/conf/windowrules.lua), allowed by allow_tearing.
• Direct scanout for game windows (render.direct_scanout = 2), so a fullscreen game skips the compositor.
• Adaptive sync (VRR) for fullscreen windows (misc.vrr = 2).
• No dimming or locking while anything is fullscreen, games and videos alike.
• Steam dialogs float: the friends list, settings and properties windows open centered instead of taking a tile.
• Sharp Steam UI at fractional scaling: STEAM_FORCE_DESKTOPUI_SCALING follows the monitor scale (hypr/conf/autostart.lua).

Proton-GE

Open ProtonUp-Qt, add the latest GE-Proton for Steam, restart Steam, then pick it per game: Properties → Compatibility → Force the use of a specific Steam Play compatibility tool.
