I just received my 2017 5k iMac (3.4/256/570). I installed bootcamp and two games on it: overwatch and CS. Overwatch plays just fine but as I show in the video below, when I launch CS this awful noise comes from the internal speakers. This does not happen when playing overwatch.

This happens even when I have external speakers attached. The noise is quite loud too, I had to lower the volume all the way in the video. The noise does not go away until I close CS.

Anyone have any idea what this could be? Everything else seems to run just fine.

Thanks.
