Horrible screen tearing with mouselook script

Im working on a prototype game for use with some of my ideas. I started the project a while ago and I recently restored my computer to factory settings and wiped my hard drive for a clean install. I reinstalled unity and brought my projects back from my backup. Without any other changes to the PROJECT, I get massive screen tearing when I try to use my mouse to interact with my look script, but my FPS remains at a decent value. I recently included X360 Controllers in my script and found that while using the controller, I get no tearing whatsoever, and my FPS remains at 60 fps almost constantly. Do I possibly have issues in my project settings? Or maybe its an issue with my new install? Maybe driver issues? Thanks in advance.

It wouldnt hurt to try to clear everything in your project settings folder. Try that and run it like it was.

I found the solution. I was running my code for player movement and camera control under Update(). I moved this code to FixedUpdate() and everything is smooth again.
