My convertet sens (from r6) is 3.5 in battlefield at 800 dpi. But if i am converting to 400 dpi my battlefield sens is 10.4. But why isnt it 7 at 400 dpi?

Sorry for bad english.

 

This is one of the main reasons the calculator exists, many games do not scale 1:1 with distance. So you can't assume it works to half the DPI and double the sensitivity.

Think about it this way, Battlefield supports 0 and even negative sensitivity, so if your sensitivity is 0 with 800 DPI you can't double it to get the sensitivity for 400 DPI.

Ohh thank you very much for the fast answer
