Summary
OpenGameBoost is an open-source gaming optimizer for 64-bit Windows 10 and Windows 11. Its Game Mode can suspend Explorer, browsers and game launchers to free CPU and RAM, then resume those processes when Game Mode is deactivated. It suspends processes rather than killing them. Other functions flush unused process memory, switch to the High Performance power plan, change network settings and adjust game GPU scheduling priority through registry changes. The original power plan is restored when optimization is turned off. Automatic game detection can activate Game Mode for listed supported games, including Fortnite, Counter-Strike 2, Valorant and Minecraft. Supported launchers include Steam, Epic, Battle.net, EA, Ubisoft Connect and GOG; listed browsers include Chrome, Firefox, Edge, Opera and Brave. The project says it has no hidden functionality or telemetry and uses the MIT License. The README directs users to download OpenGameBoost.exe from Releases and run it as Administrator; full functionality requires administrator privileges. Running from source requires Python 3.9 or later. The project says system changes are reversible and advises users to use it at their own risk.
Who it is for
It suits Windows 10 or 11 users who want to manage game-related processes and system settings with manual controls or automatic game detection. Users must be able to run it with administrator privileges.
What is good
- Game Mode suspends and resumes processes rather than killing them.
- Restores the original power plan when deactivated.
- Automatic detection supports 18 listed games.
- Project says it has no telemetry.
What to know first
- Requires 64-bit Windows 10 or Windows 11.
- Administrator privileges are required for full functionality.
- Modifies Windows settings; users assume risk of resulting issues.
- No game profiles or performance overlay.
Verdict
OpenGameBoost combines process management and several Windows setting changes, with automatic detection for supported games. It requires administrator access and modifies system settings, although the project says those changes are reversible.
