OpenGameBoost
What it is
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 deactivated. The tool 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 ends, and the project says system changes are reversible. Automatic detection can activate Game Mode when supported games launch; the list includes Call of Duty, Fortnite, Apex Legends, Counter-Strike 2, Valorant, League of Legends, 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 reports no hidden functionality or telemetry and uses the MIT License. Download the executable from Releases and run it as Administrator; source use requires Python 3.9 or newer.
