Microsoft’s limited explanation of Game Mode also says that, in Game Mode, Windows Update won’t automatically install hardware drivers or notify you to restart your PC while you’re playing a game. The game you’re focused on playing gets more CPU and GPU resources, while other applications and background processes get fewer resources. This only works if Windows 10 detects that you’re playing a game. Technically, it works by detecting games and giving them priority access to your computer’s resources.
Here’s the official description: Microsoft says that Game Mode “helps achieve a more stable frame rate depending on the specific game and system.”
First introduced in Windows 10’s Creators Update, which was released back in April 2017, “ Game Mode” promises to boost the performance of many PC games.
