Games, especially online games, are some of the most demanding PC applications in existence. Because of the need to provide near-instant reaction to users' actions, lack of processing power will result in delays in packet transmission, adversely affecting the gaming experience.

GameSafe's gamer mode can be turned on with one click. When activated it will:

Minimize processor time & memory consumption
Postpone automatic updates & scans
Eliminate all alerts and pop-ups
Scan only the most important files

Processor time 
Processor time used is probably the best measure of "responsiveness". Background processes that dramatically reduce CPU cycles (like on-access antivirus) are highly undesirable.

Memory consumption 
The amount of memory antivirus scanners use, greatly influences the overall "responsiveness" of the operating system.
