Mouse movement at the hardware level isn't smooth either. The only way to render smooth movement is to buffer the change in mouse cursor position and apply the change over time. This can cause a problem in its own right by introducing what's known as input lag. This is how long it takes for the game to catch up to movements made with the mouse or inputs from any other device.

That being said, addons don't have the ability to change the way the game renders the world. Also, the lack of movement smoothing isn't really an "issue". The game is working as intended and just doesn't have this feature.



PS: This isn't anything close to micro-stuttering. Micro-stuttering is entirely a GPU problem and very rarely has anything to do with the game engine itself. It's when frames are delivered to your monitor slightly out of order and causes a jitter effect as a result when moving. This is a more common occurrence when running in multi-GPU setups. Micro-stuttering is identified by brief and often frequent appearances of frames that seem to have moved the picture backwards before jumping forward in time.
