Valve continues Develop a composite server GameScope (previously known as SteamCompmgr), using Wayland protocol and used in the operating system for Steamos 3 . February 1 in GameScope was Added Support SuperMepling technology AMD FSR (FidelityFX Super Resolution), which allows you to reduce the loss of quality pictures when scaling on high-resolution screens.
The Steamos 3 operating system is based on Arch Linux, comes with only accessible to reading the root FS, supports FlatPAK packets and uses the PipeWire multimedia server. Initially, Steamos 3 is developing for the Steam Deck game console, but Valve also promises that this OS can be downloaded separately on any computer.
GameScope is positioned as a specialized composite server for running games capable of working on top of other desktop environments and providing a virtual screen or a separate insulated XWayland instance for games using the X11 protocol (a separate update and permission can be configured in the virtual screen). Improving performance is achieved by organizing output to the screen via direct access to DRM / KMS without copying data to intermediate buffers, as well as due to the use of funds provided in the VULKAN API for asynchronous computing execution.
