Game Input MultipleXer

I've been trying to modify the PS4 Battlefield 4 foxy config for my personal setup. However, when I have found a decent setup DZ, sens and acc-wise, whenever I press left shift (for sprinting, toggled), the mouse movements become ultra sensitive. Has anybody else encountered this? In short, my problem is that when just walking everything works great when aiming, but when I start to sprint the slightest mouse movement makes me perform a rotation of about 180 degrees.

There's a third profile in that config!
It's possible to remove it using gimx-config.

Thanks for the swift reply! I'll look into the gimx config
