How to increase chuvstvitelnosti mouse in the game? (Tom Clancy's Rainbow Six: Siege)

If you have adjustable Sens on the mouse (Bloody 8), but I have a bad habit to press the button (double nagative on it include regime change Sosny) of her shift and while scrolling with the mouse wheel, I have sence changed, so I disabled this feature and every time you just touch the icon dipiay I do not, because the Siege is not the only game on the planet, and not the most interesting to her for so many unnecessary movements to do. So. If it is possible to increase the Sens? I have all Maxim unscrewed, Mr. oats is still quite low (which is half my usual Sens).
PS. Dipiay I have about 400-500, don't remember exactly
