Gamescope is a Wayland micro-compositor that manages frame rates, resolution upscaling, shader application, and virtual displays. It functions as a system to isolate applications within a sandboxed session and control their display output.
The project provides a virtual display manager that spoofs resolution and refresh rates to create a consistent screen environment independent of physical hardware. It includes a GPU post-processing wrapper to apply visual shaders and filters to an application stream and a game resolution upscaler to improve visual clarity on larger displays.
The system manages frame rate limiting for focused and unfocused windows and utilizes asynchronous compute and direct flipping to reduce input lag. It also features a scripting extension interface that executes custom scripts via operational hooks to modify configuration and behavior at runtime.
