W.O.P.R. – Steam Gaming Mode Launcher for OMARCHY (Arch)

“Shall we play a game?”

W.O.P.R. is an opinionated Steam “gaming mode” launcher for Arch-based systems running Hyprland.

It installs all the bits you need for a SteamOS-style experience (Steam, Gamescope, MangoHud, GameMode, 32-bit libs, GPU drivers), wires everything into Hyprland keybinds, and gives you a friendly TUI to pick resolution and performance overlay before it launches Steam.

Once installed:

• SUPER+SHIFT+S → enter Gaming Mode
• SUPER+SHIFT+R → exit Gaming Mode and restore your desktop
