Cause 3: DVR mode does not work properly

DVR mode runs by default in the background, using system resources, which can cause lag in games, especially demanding ones. This Microsoft feature is designed to record video and take screenshots during gameplay, but not all gamers take advantage of it.

After installing Windows 10, the mode is enabled by default, (although it may have been disabled before, so there are no problems with games either). Turn it off and check if the problem is gone. You can do this through Xbox's own software that comes pre-installed on your PC, as well as through the Xbox app. "Settings". o "Registry Editor". All methods are explained in our other manual.
