Games that support monitor distance (BF4, BF1, BFV, Black Ops 4) will now through magic use your conversion setup and resolution to calculate the most appropriate coefficient for MDH, MDV and both Viewspeeds.
This will make all the aims scale to your preference without you having to figure out the coefficient yourself.
The calculated coefficient will be a placeholder value for the sensitivity field, so you can override if you like. If you want to use the calculated value just delete any value you have entered.
