It supports both games using Proton and native Linux games and works on both X11 and Wayland. An incredible wrapper with a menu that lets you easily toggle and modify various settings for games on Linux. Anything from proton versions to startup and exit scripts, proton/dxvk/etc. settings, FSR, reshade, and even options for various tools like game mode, replay-sorcery, game scope, etc. Tons more too. I just set my default proton version to "steam tinker launcher" and then every game launches with a 2-second menu that allows you to easily change any of the settings. If you don't press any buttons it just goes with the defaults and launches the game.

    Rofi

    Rofi

    A window switcher, application launcher and dmenu replacement

    Rofi started as a clone of the simple switcher, written by Sean Pringle - a popup window switcher roughly based on a super switcher. Simpleswitcher laid the foundations, and therefore Sean Pringle deserves most of the credit for this tool. Rofi (renamed, as it lost the simple property) has been extended with extra features, like an application launcher and ssh-launcher, and can act as a drop-in menu replacement, making it a very versatile tool. Rofi, like dmenu, will provide the user with a textual list of options where one or more can be selected. This can either be running an application, selecting a window, or options provided by an external script. It's not an application that can support every possible use case. It tries to be generic enough to be usable by everybody. Rofi has several built-in modes implementing common use cases and can be extended by scripts (either called from Rofi or calling Rofi) or plugins.
