The issue:
The Frame rate is erratic, both in the editor and in the game when compiled, even though I'm using a time.deltaTime to rotate the camera, nothing fancy going on here, which is why it's peculiar, I looked therough the Profiler, but could see nothing of mine that would cause this.

To reproduce:
Run the game in editor or in game, and watch for hitching in horizontal movement, this also has nothing to do with vSync, since that involves tearing, not hitching.
