Dynamically adjust process priority of background applications to maximize game performance
GameBoostHD is a tiny application that will watch for various game launches. When a game is detected, GameBoostHD will lower the priority of common background apps that often use CPU. This includes things like game launchers (Battle.Net, Steam, etc) and web browsers (Chrome, Firefox, Opera, IE). The system power profile will also be set to "High Performance" while a game is running. This will hopefully improve performance of the game (increased FPS and fewer stutters) as it won't be competing for timeslices with other processes.
- Diablo 3
- Dota 2
- Half-Life 2
- Heroes of the Storm
- League of Legends
- Left 4 Dead 2
- Quake Champions
- Rocket League
- StarCraft 2
GameBoostHD has no installer or user interface. Simply run the .exe file and the program will be running. It will work continuously until a shutdown / reboot. It's written in C / Win32 API so it's extremely lightweight and will use minimal resources running in the background. If you want it to run when you start your PC (recommended), make a shortcut to it in your Start / Programs / Startup folder or set up a scheduled task.
The program will work on 32 and 64 bit Windows Vista / 7 / 8 / 10. No additional files are needed, just unzip and run.
