Toolwiz GameBoost FREE aims to optimise your PC to deliver the maximum possible performance, using three speedup ideas.

The first claims to "defragment your memory". In our experience this isn't likely to be of the slightest use, but if you agree then you can tell the program not to bother by clearing a checkbox so it's no great issue.

The second approach sees the program "defrag the path of the game", which may be more effective: try it and see.

And the third approach sees GameBoost disable various Windows features to free up system resources: Aero, task scheduler, printer support and more. You may not want to turn off everything here (Windows updates, network shares and so on), and also we're not entirely sure what every option does: "Stop Graphics Scanner and other Device", for instance?

But those concerns aside, the program is at least easy to use. You can get started with the default settings just by clicking Enter GameBoost Mode, then try a game and see if you notice any improvement. And when it's all done, close the program and your original system settings will be restored.
