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.
