In most games that I play (Rainbow Six, Battlefield 1) my CPU (i5-4460) is being maxed out at 100% usage, while my GPU remains at around 70%. I have set the settings to ultra but it does not work. When I look in the task manager, and go to 'Details', the game only uses 20-30% and system idle processes uses the rest, but that's probably because the game is minimized. What can I look into that could be causing this?
