GBoost improves game speed by closing all programs that are running and that are using a lot of system resources such as processor and memory.
It displays a nice graph with CPU usage, free memory and services.
In “Advanced mode” you can turn off different programs that are active on your computer and see the improvement in more CPU and free memory.
By default, the program is set to close all programs that are not necessary for gaming, but if you want to prevent that or you receive an error, go to Options and disable “Auto Kill Processes”.
Is a good replacement or equivalent of popular tools such as IObit Razer Game Booster and others.
