btw, from what Wizard you said, I assume it means that you tested, and found that there isn't any differences compared to OW1?
As in, the FOV system used is identical, and the way the screen is distorted for the FOV is also identical?
I tried to do some simple testing myself, but I can't find out any mouse smoothing in the game. It feels like moving your mouse fast and slow results in the same distance.
Yet when playing the game, I can clearly feel it is "difficult" to turn the camera a long distance.
I do "feel" that playing around with controller settings changes mouse behavior. But yeah, it's a really weird thing.
