Fortnite DPI / sensi unlike pro players?

I'm currently playing with the Roccat kone aimo, and I would like to have the sensitivity x / y of Mongraal as an example,

prosettings.net states that he plays with 800 DPI and a sensi of "0.050". In the stream, I also saw that the X / Y sensi is really at 0.050, but if I put in the Roccat software to 800 DPI, and in Fortnite to 0.050, I have to pull the mouse over the whole mousepad once to me to move a bit.

Is it because of the software that I have to make my sens on about 600 that I can play reasonably normal or what can it still be?

Now you know why it's called esports. Playing low sense goes pretty well on the arms. XD

Something must be wrong, because with the Handcams it is never so extremely really extremely slow

Do you have any weird settings in windows regarding muzzle velocity / acceleration?
