Typically 100/100 horiz and vertical, 0 aim smoothing, 100 aim assist, 20 aim assist window for the large majority of my heroes. (Mercy doesn’t have aim assist though).
Widow? 65/65 horiz/vertical, 0 aim smoothing, 100 aim assist, 25 aim assist window, 65 in-scope sensitivity.
*100 is still too slow for me for main sens
