  1. Game Booster

    Check memory use before and after cleanup

    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.

    Memory cleanup

    The interface compares memory use around a cleanup action.

    Game Booster beside Windows tools

    The app sits beside Windows tools so activity is easy to inspect.

  2. Game Booster

    Choose what stays open

    Review background apps before closing or suspending them. Save your work first: closing an app can force it to stop.

    Background processes

    Review the process list before suspending or lowering a task.

    Windows options

    Open available Windows settings from the same interface.

  3. Game Booster

    Make a game setup repeatable

    Choose which actions run when a game is detected. Review the app lists first; apps that are closed will not reopen when the game ends.

    Performance setup

    The performance panel groups the session options in one place.

    Game automation

    Choose actions that run when a selected game is detected.

  4. Game Booster

    Check NVIDIA support before tuning

    GPU and video-memory clock controls require supported NVIDIA hardware and drivers. Overclocking can cause crashes, overheating, or hardware damage; leave these controls alone unless you understand the risks.

    GPU and vRAM controls

    Inspect the graphics controls listed for supported NVIDIA systems.

    Configuration

    Adjust the available settings to match your own setup.

  5. Game Booster

    Check system activity and hardware

    Check CPU and memory use alongside your hardware details. GPU activity and temperature readings are available on supported NVIDIA systems.

    Performance monitor

    View CPU and memory use, with GPU readings on supported NVIDIA systems.

    Hardware details

    Check system and graphics information before choosing settings.

Check what is running before you change it

Game Booster puts system readings, background-app controls, and Windows maintenance tools in one place. Check CPU and memory use, review the apps running alongside your game, and choose the settings you want to change.

Choose your game-session actions

Bring Game Booster to the front after launching a game and check the detected game. Detection can trigger memory cleanup, app closure or suspension, priority changes, and a Windows power-plan change. Review the separate close and suspend lists, and save work before enabling app closure. Closed apps will not reopen when the game ends, and file-cleanup timers can run outside a game session.

Cleanup controls remove temporary files, configured caches, and crash dumps, or empty the Recycle Bin. Check the selected action first: cleanup deletes files directly rather than offering a file-by-file approval screen.

NVIDIA graphics tools

GPU readings and GPU/video-memory clock controls require supported NVIDIA hardware and drivers. AMD and integrated graphics are not fully supported. Overclocking can cause instability, overheating, or hardware damage, so leave it alone unless you understand the risks. NVIDIA driver-setting changes can affect other games too.

    "Been using Jitsumi Booster.exe for a little while now and I’m honestly impressed with the performance boost. It noticeably improved responsiveness and helped reduce lag/stuttering during gaming and multitasking. The interface is simple, lightweight, and easy to use without a bunch of unnecessary clutter. Setup was quick, and the optimization features actually made a difference compared to other ‘booster’ apps I’ve tried. Definitely worth checking out if you want smoother overall system performance."

    "Pretty damn good for a game booster. Just dumb people who don't understand how to use it downvoting it. It even let's you ajust you video card setting better then the NVIDIA control panel let's you. So..... Up to you how you wana use it. But if you arnt tech savy I'de stay away and go with another game booster that is more "user" friendly."

Before you install

Common questions

What to check before you install or change a setting.

Will it increase my FPS?

There is no guaranteed increase. It depends on the game, your hardware, and what else is running. Compare the same game scene before and after one change. Game Booster shows system activity, not an FPS counter.

Does memory cleanup make my PC faster?

It can reduce the memory held by background apps at that moment, but they may use memory again as they work. A lower memory reading does not by itself mean a game will run faster.

What should I check before closing background apps?

Save open work and review the app list. Closing can force apps to stop. Leave security tools, anti-cheat, drivers, and anything you need for chat, recording, or cloud saves running.

Do I need Steam?

Yes. Game Booster starts through Steam. Check the requirements below and the Steam page before installing.
