TenZ's sensitivity in Valorant is relatively low compared to many other professional players, which means he has to make larger hand movements to achieve the same in-game movements compared to other players with higher sensitivities.
TenZ's in-game sensitivity is set to 0.36, with a DPI of 800. This translates to an eDPI (effective DPI) of 288, which is considered quite low (complete TenZ Valorant Settings).
In comparison, some other professional players have higher sensitivities. For example, s1mple from CS:GO has an eDPI of 880, while ScreaM from Valorant has an eDPI of 352.
However, it's important to note that the "best" sensitivity for an individual player can vary depending on their personal preferences and playstyle. Some players prefer higher sensitivities for quicker reaction times and more precise aiming, while others prefer lower sensitivities for more consistent and controlled movements. Ultimately, the best sensitivity for a player is the one that allows them to perform at their best.
