As a headsup: The multiplier mouse-sens uses is not right anymore. They did an update to how mouse movement ist calculated in late 2016 to better log makro abuse or smth.
But whatever: i made a paper to test this, 1000dpi with 23cm 360°, line to line on my paper i need something between 0,255 and 0,265 ingame (while mouse-sensitivity says 0,23 which ingame is more like 24,5 to 25cm 360°). Would be cool to get this updated.
Game on
