If your PC games are lagging or running slow, you can free up resources in Windows 10 using a new XBOX Game Bar task manager that overlays on top of running games.

Earlier this month, Xbox Insiders began testing a new 'Resources' feature of the XBOX Game Bar that can be accessed as an overlay in games by pressing the Win+G keyboard combination.
