So I always want the same sens based off FOV on every game I play.
I converted my sens from Apex to Shatterline (120 for shatterline)
Apex sens: 1.407021 (FOV 100, 4:3) (FOV 115.633556, 16:9)
Shatterline: IDK (FOV 120, 1:1) (FOV 144.016602, 16:9)
Then i use this: https://jscalc.io/embed/Q1gf45VCY4tmm2dq
To convert my Apex sens from 115 FOV to 144 FOV.
= 2.726550
then I convert this to shatterline sens with your calculator
= ~ 86
And it was to fast
So i did the same steps with 16:9 and 4:3 and see if Shatterline was using another FOV Type.
Using kovaaks and Shatterline to easily recognize the sens feeling.
4:3 was too fast and 16:9 was spot on.
