Steam Play compatibility tool to run adventure games using native Linux ScummVM

Wine GUI using Zenity

GameMode is a Linux system daemon that automatically applies CPU, GPU, and I/O performance optimizations when a game starts and reverts them when the game exits. It coordinates system-level tweaks by reading a plain-text configuration file, switching the CPU frequency scaling governor to performance mode, adjusting the I/O scheduler for low latency, and setting the graphics card to a high-performance power state through direct sysfs or driver interface writes. The project includes a daemon that communicates with game launchers via Unix domain sockets, a hybrid GPU launcher that wraps game exe

MangoHud is a Linux hardware monitor and performance overlay that displays real-time metrics and frame rates. It functions as a graphics API hook, intercepting Vulkan and OpenGL pipelines to render performance data directly onto the graphics buffer. The project serves as both a real-time monitor for CPU and GPU utilization, temperatures, and power draw, and a frametime data logger that records execution speed to disk for later benchmarking and analysis. Users can modify the overlay display, visual styles, and active metrics through configuration files, environment variables, or predefined pe

Steamtinkerlaunch is a game launch wrapper and Wine prefix orchestrator designed to manage the execution environment of games on Linux. It functions as a compatibility layer manager that downloads and organizes custom Wine and Proton versions, while creating isolated filesystem hierarchies and registry hives to prevent configuration conflicts between games. The project specializes in automating the installation of mod managers and script extenders within these isolated environments. It acts as a post-processing shader injector, managing the installation and dynamic library overrides required

Decky Loader is an open-source plugin system that extends the Steam Deck's gaming mode interface with community-made plugins and customizations. It functions as a plugin loader that injects JavaScript plugins into the Steam Deck's web-based interface at runtime, enabling real-time appearance and behavior changes without leaving the active gaming session. The system combines a CORS-bypassing proxy layer that intercepts and modifies HTTP fetch requests from plugins to remove same-origin restrictions, with a Python-to-TypeScript bridge that exposes Python functions as callable TypeScript methods
