    I got a datas from expriment below
    200 1/5
    100 2/6
    50 3/6
    25 4/6
    12.5 4/5
    10 5/6
    5 10/11
    1 2.941176

    then simply derived to 
    velocity * 50 / (50 + x)

    and It applies earlier than 
    FixedUpdate

    Yes, I know what drag is and I replied above giving you links. What else is it you want?

    3D Physics is PhysX. The link is above.

    I think he just wanted to say that he reverseengineered the formula for drag, but i could be wrong :D.

    wait I got some misunderstanding.
    the actual formula was 
    velocity /= 1 + drag * Time.fixedDeltaTime
