OpenGameBoost is a free, 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. Other options include flushing unused process memory, switching to the High Performance power plan, changing network settings, and adjusting game GPU scheduling priority through registry changes. The original power plan is restored when optimization is turned off. Automatic detection can activate Game Mode for supported games; the listed titles include Fortnite, Counter-Strike 2, Valorant, and Minecraft. Supported launchers include Steam, Epic, Battle.net, EA, Ubisoft Connect, and GOG. The project says it has no hidden functionality or telemetry and uses the MIT License. The README directs users to download the executable from Releases and run it as Administrator. Full functionality requires administrator privileges; running from source requires Python 3.9 or later. The project says changes are reversible and advises using the software at the user's own risk.
Who it is for
It suits Windows 10 or 11 users who want manual or automatic controls for suspending background processes during supported games. Users comfortable granting administrator privileges can access its full functionality.
What is good
- Automatically detects listed supported games.
- Suspends rather than kills processes, then resumes them.
- Restores the original power plan when deactivated.
- Distributed under the MIT License.
What to know first
- Requires 64-bit Windows 10 or Windows 11.
- Full functionality requires administrator privileges.
- Running from source requires Python 3.9 or newer.
- The project advises using it at your own risk.
Verdict
OpenGameBoost combines process suspension with memory, power, network, and GPU-priority adjustments. It requires administrator access and changes Windows settings, which the project says are reversible.
