GameBoostHD

Dynamically adjust process priority of background applications to maximize game performance

About

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) and web browsers (Chrome, Firefox, Opera, IE). This will hopefully improve performance of the game as it won't be competing for timeslices with other processes.

The idea behind this came about when I was playing Overwatch and noticed the Battle.net launcher was using up to 12% of my CPU due to the animated GIFs and javascript and whatever else it was running. Using GameBoostHD won't reduce the CPU usage percent - it only alters the scheduling priority. For example, after running GameBoostHD, the Battle.net launcher will never be allowed to "steal" CPU attention from Overwatch, but if there is spare CPU power it is still allowed to use it.

Usage

GameBoostHD has no installer or user interface. Simply run the GameBoostHD.exe file and the program will be running. It will run 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, make a shortcut to it in your Start / Programs / Startup folder.

Download

The program will work on 32 and 64 bit Windows XP / Vista / 7 / 8 / 10. No additional files are needed, just unzip and run.
