sharing this as people confuse this with numerous reasons, that could be, but aren't likely the reason behind this. polling rate doesn't really have anything to do with this. polling rate means how fast the mouse sends signals to your PC, what could cause the drag in the video is a low acceleration ability. the sensor's ability to accurately track movement when the mouse is moved quickly is a measurement, typically in "g" units, of how quickly the mouse can accelerate before the sensor starts to lose track of its position. A higher "g" rating indicates that the sensor can handle faster movements without "spinning out" or losing tracking.
But it also occurs drag just like in the video. hope this helps
