A big amount of players, who have played a competitive shooter or two will know, that in order level a field with mouse and keyboard players, the sensitivity has to be adjusted to allow more quick movements, along with that DEADZONE settings have to be adjusted as well, most commonly by setting it to 0% or the lowest amount that the stick drift, if its present, would allow it to. but lack of the aim deadzone settings is a incredibly harsh especially if you combine it with aim assist not being available in cross play games with PC Players, since, the distance the aim stick has to travel for it to be considered as moving is to large, compared to the sensitivity the players have to use when using controllers. To have a competitive advantage without aim assist, the Players have to increase the sensitivity almost to the maximum allowed value, which is also fine for most if not all competitive games with crossplay, but. Without being able to set the deadzone lower than the default value, you have to move the stick A LOT before it starts moving in game, and since the sensitivity is to high, it is exponentially harder to make fine aim adjustments leading to the only possible solutions: disabling crossplay, and forget about playing with friends, or buying a PC.
