Lag movement with high fps

[haxx4real]

So i was playing fine until the movement starts stopping randomly like with jetpack it would stop mid flight and then back on again.I cant go walking in a straight line without stopping 3 or 4 times and it doesnt freeze just stops because everything around keeps moving when this happens. i tried many things none worked .My fps is constantly 150+ even when this spikes appen. i have no idea, if someone know how to fix pls help 

Repluged keyboard and now its fine
