Feedback from a user, which I am posting here to centralize:
Firefox 64, AMD FX8350, GPU Radeon R9 380, 16GB DDR3
16.7 ms starting point, starting rotation of the character
16.7 ms same position but looking back, at the rear mirror
24 ms Looking at that same mirror, but with the butt colliding with the green sphere
16.7 ms just in front of that mirror
25 ms looking at the 3 small mirrors being just in front of the sculpture
The more I move the mouse in this place, the slower it gets (While recording it is slower, obviosly, so don't trust those numbers. I got it to 30 ms instead of what appears in the video)
