FMoveRunMult

fMoveRunMult
Default value	4
Description	This setting controls how much faster an actor will move when they are running compared to walking speed. This setting applies to NPC actors too, not just the player!

Note: changes to this value will not be reflected until an actor re-evaluates its speed. This can be done by changing sneak state or holstering / unholstering a weapon. Changing walk/run state will not work.

A possible workaround is to do 1 point of mobility damage to the actor then heal it a frame later. This should cause their speed to recalculate.
