The Top Five Game Boosters - The Epic Showdown

The core idea is to kill services, processes, background tasks and programs that are not required to run the game or the operating system to free up RAM, reduce CPU load and disk activity.

The question we are going to answer is if running Game Booster software has a positive effect on a PC game's performance or if the gain is negligible or even counterproductive.

The setup

  • Intel Core i-2500K CPU @ 3.30 GHz

  • 8 Gigabyte of RAM

  • NVIDIA GeForce GTX 560 Ti video card

  • Corsair Force GT Solid State Drive

  • Resolution: 1920x1080

  • Windows 10 Build 10122

  • Benchmark 1: Star Swarm Stress Test (default settings)

  • Benchmark 2: Resident Evil 6 (default settings)

  • Benchmark 3: 3D Mark Demo (default settings, primary tests)

The Game Booster List

Game Fire

Game Fire 4 uses a profile system that determines which services, background processes, features and programs are stopped when game mode is enabled.

You need to make that decision as it does not ship with a default profile. A long list of features can be disabled including network access and sharing, Windows Search, visual effects or Windows Defender.

In addition to that, it supports the termination of custom services and applications that you need to specify for each profile you configure.

Game Fire 4 displays a list of applications and services that you can terminate when you enter game mode.

Other features that it supports are game defragmentation and quick access to Windows tools such as Memory Diagnostics or the Performance Monitor.

IOBit Game Assistant

The program scans the system for installed PC games and displays those in its interface. It supports custom games as well as you can add those to the list of games.

Game Assistant supports an automated mode that cleans RAM when enabled. Instead of using that mode, you may select processes manually that you want closed to free up RAM on the system.

Since it seems to do nothing else than stop processes and free up RAM, it may even be less effective than other boosters especially if the system has plenty of RAM.

Razer Cortex Game Booster

Game Booster requires that you create an account before you can run the program. It scans the system for installed games and displays them in its interface.

The program uses a recommended boost by default but provides you with the means to customize the boosting.

It lists plenty of options to do so, from terminating processes and services to tweaks that you can apply to the system.

ToolWiz Game Boost

The program is as simple as it gets. It displays several boost options on start, for instance to stop scheduled tasks or network shares while in GameBoost Mode.

Since all options are selected by default, it is only a matter of enabling game mode in the program to get started.

It lacks advanced features like disabling services or terminating processes that other programs in this test support.

EZ Game Booster

The highlight of the tool stems from the fact that it helps you identify unnecessary processes and services that are running in the background and suspending them. As a consequence, your processor, RAM and video card are going to have free resources that can be employed for enhancing the PC game you want to play


In addition, the program includes a useful defragmentation tool that enables you to speed up the loading and running of games you usually play. On a side note, the function can just as well be used for applications you have installed on your computer.

Analysis of results

Default results and boosted results are in close range of each other in all tests and it is likely that users notice improvements when they run these tools to improve gaming performance.

For instance, if you run a BitTorrent client or large file download in the background, it may impact game performance significantly.

Some booster apps offer additional features, like screen capturing which you may find useful.
