Razer Cortex causes crazy input lags

Hey there

I downloaded Cortex by my friend's recommendation today. Cortex did help for FPS and loading speed for textures in GTA V, however I have high input lag playing with my Dualshock 3 (SCP Toolkit) controller. (High as in +1 second latency.)

Made a check through my gamepad viewer, it looks alright.

The issue occured at all games at first, somehow I got it fixed in Rocket League, but in GTA V latency increased. (GTA V got a defrag too.)

What causes this? Are there any way to fix it?
Thanks for your help.
