Check PC activity with Game Booster, keep shortcuts nearby with Gaming Overlay, or choose a screen tint with Blue-Light Filter.
Inside Game Booster
Two short recordings from the Windows app show the memory view and cleanup controls. Playback is optional; the captions explain each clip.
Game Booster
See the memory readings and cleanup controls in the app. Memory use can rise again as background apps continue working; a lower reading does not guarantee higher FPS.
The interface compares memory use around a cleanup action.
The app sits beside Windows tools so activity is easy to inspect.
Two more tools
Gaming Overlay opens app shortcuts where your game and display mode allow it. Blue-Light Filter gives you a tint and same-day schedule you can adjust.
Quick access
Open app shortcuts and reference pictures, check CPU and memory use, and adjust audio from an overlay menu.
Screen tint
Choose from three screen-tint strengths, set a same-day schedule, and use a scratchpad for notes during your session.
Jitsumi makes three Windows utilities: Game Booster for system readings and game-session controls, Gaming Overlay for shortcuts and picture references, and Blue-Light Filter for screen tint.
See the controls in the screenshots and demos, then check the requirements before choosing a tool.
