If you disabled both of those, and you were at 100 FPS when that happened in the video, I don't know what it is.
G-SYNC can flicker at low framerates (30 FPS or under) on some TN panels, but the brightness doesn't fluctuate like your video.
It could be your monitor. I would not go so far as to say it is faulty or broken though.
Have you contacted Acer and shown them the issue?
