Game Mode is a term coined by Microsoft for computer gamers. This mode helps users to use the most of the system resource for the game so that the gamer can get a much better user experience. To get rid of unwanted lagging, frame rate lacking, etc. this mode has been introduced in Windows 10 V1703 or Creators Update. After enabling Game Mode, your computer will use most of the CPU and GPU power to play the game. Unwanted and non-priority background processes will be stopped automatically. Unwanted background processes include random anti-virus scans, etc. – unfortunately, there is no option for a user to stop or run a particular background process while having Game Mode enabled.
