Posting again for at least one more page:
I desperately want to make my aim down sights mouse sensitivity in Titanfall match what it is in Battlefield 4 (which I believe to be 0.6 times my hipfire sensitivity).
I found in a Google search that you can add this to the CounterStrike: GO config to achieve the same thing in that game:
bind MOUSE2 +sens
alias +sens "sensitivity 1" //Mouse Sensitivity when holding down right Mousebutton.
alias -sens "sensitivity 5" //Mouse Sensitivity when right Mousebutton is released.
I figured this might work in Titanfall since it is also based on Source engine, but Titanfall just overwrites my config files whenever I add this to them and removes the lines.
Anyone have any ideas on modifying aim down sights sensitivity separately from hipfire? Someone else must be interested in this.
Perhaps make the config file read-only?
Or if that doesn't work maybe adding a line to the config file to 'exec autoconfig.cfg' and add those two lines inside that autoconfig.cfg file.
