Game Booster is an easy-to-use program that shuts down unnecessary system processes in order to improve the performance of resource-thirsty games. With an intuitive interface that makes it easy to switch between gaming mode and normal mode, Game Booster is a simple but powerful program.Game Booster's interface is basic, with a list of 24 noncritical processes that can be shut down during gaming. Check boxes allow users to select specific processes. It is true that you have to take a leap of faith with some of these; if you're not extremely computer savvy, you may have no idea what it is that you're shutting down. We can say that our system suffered no ill effects from temporarily disabling all of the listed processes, and the program quickly started them again when we switched back to normal mode. We do wish that the program came with a Help file that went into detail about this issue, though. In addition to disabling unnecessary system processes, Game Booster offers a game defragmenter that specifically defragments the game directories, allowing a given game to start and run more quickly. Overall, we found Game Booster to be both easy to use and effective. We noticed a significant difference in game performance when using gaming mode, and we think this is a great choice for users who need to optimize their systems for gameplay.Game Booster is free. It installs and uninstalls without issues. We recommend this program to all users.
