Doing some more tests. I realized that with this process of turning the camera sideways. My CPU usage goes from 36% to 100% and only returns to normal after I stop playing with the camera.
This happens when I use the video settings at maximum or minimum, not making any difference.
Remembering that my processor is an I7 7700k
