Whenever I play a 3D Game, after 20 minutes or so, my Nvidia GPU usage drops from 40 to 0, my CPU drops from 30-40 to 10, but my Intel GPU goes up to 100%, causing INSANE fps drops for 1 minute, then everything turns back to normal and then glitches again soon after. Watching in Task Manager, Desktop Window Manager is the cause of the problem. Is there anything I can do to fix this?
