GlouOSGame Mode
When you launch a game, GlouOS shifts the whole system into Game Mode. Here is what that actually changes.
Gamescope and the display pipeline
GlouOS integrates Gamescope, a micro-compositor that gives clean, tear-free frame pacing. On a Wayland desktop with variable refresh rate, frames are shown the moment they are ready, and HDR is supported on capable displays. You can cap a game's frame rate just below your monitor's refresh for the lowest-latency VRR, and there is a controller-friendly session that boots straight into a big-picture game UI.
Power that follows the game
While a game is focused, the CPU switches to its performance profile for quick response, then returns to a balanced or power-saving profile at idle. The governor, scheduler and power settings all move together, and laptops and handhelds keep sensible battery-aware defaults.
Game first, everything else in eco mode
Game Mode raises the priority of the game and its render threads and pushes everything else down. Background tasks are moved into a capped eco mode group with lower CPU weight and I/O priority, and the usual stutter culprits (file indexers, update daemons, telemetry) are paused for the session and resumed when you finish.
Low-latency audio and online play
GlouOS uses PipeWire with a low latency setting for games, raised again for stability when you are not playing. Bad audio latency is a common, under-diagnosed "feels off" complaint, so the defaults are set to avoid it. Audio threads are also granted real-time priority (through the realtime and audio groups), so sound stays clean even when the CPU is fully loaded.
For online play, sane network defaults keep things smooth without adding jitter: BBR congestion control with the fq queueing discipline, TCP Fast Open and larger network buffers. It is exactly the set the community has settled on and nothing more, since piling on extra tuning tends to add the very jitter you are trying to remove.
Seeing what is happening
MangoHud is preconfigured, so you can bring up an overlay with frame rate, frame times and hardware usage, with a GUI for tweaking it. It is the quickest way to see the smoothness improvements for yourself.
