Microstutters when moving and turning at the same time

In Creative Mode, I built a tower of any kind of block. When I fly (orbiting) around the tower and continuously move my camera to point at it, I notice multiple lag spikes of a frame or two. This also happens if I walk or run around the tower on foot while pointing at it, or if I stand in place and turn around, but to a much lesser degree.

I'm usually getting over 60fps, and the spikes can drop it as far as below 30.
