The Windows Insiders team have released a new build for PC users of Windows 10 that are on the fast ring. This one has quite a few updates, but a big warning: some bugs will impact your gaming abilities! These are unrelated to the Game Mode, and it’s sad that these bugs surface when the Game Mode is released. However, I’m sure it will be a fixed issue next release (I hope!).
Game Mode: With Game Mode, it’s our goal to make Windows 10 the best Windows ever for gaming. Our vision is that Game Mode optimizes your Windows 10 PC for an improvement in game performance. To enable Game Mode, go to Settings > Gaming > Game Mode toggle the feature on. Doing this will give you the ability to enable the feature for each UWP and Win32 title you play by pulling up the Game bar (Windows + G) and the clicking the Settings button. There you’ll be able to opt individual games into using Game Mode. (See below for an known issue regarding Game Mode in this build.)
