Using this app is super easy: first you have to define the parameters that you want your 'gaming mode' to have. By doing so, you can deactivate a series of Windows features that take up memory and that you don't really need while you’re playing.
Once you've configured your gaming mode to meet your needs, you just need to click on it to activate it. After that step, the program window minimizes in the system and you just need to click it again in order to deactivate it.
Game Fire is a relatively useful app that can improve the game's performance. However, be warned that you can't always appreciate the frame rate changes.
