There is for ADS sensitivity. Upon opening the developer console I've discovered they have a command called sensitivity_IronSightMultiplier.
Paging @DPI Wizard to see if this actually does anything and if it does hopefully he can incorporate this into the calculator.
Seems like this is a bug. By default when I first load it up the output doesn't have the discrepancy field.
To make it appear I have to switch to Simple then back to Advanced calculator mode.
Thank you! I missed that completely!
I fooled around in a custom server with 100 FOV and the sensitivity felt right so I wanted the equivalent in the default 90 FOV.
I would like to report that if you edit the FOV value using the config file and it has decimal values, the game will just backup that config file and generate a default one.
Look sensitivity is fine though.
