When playing on a server, everyone in the game has minor/moderate stutter.
I have experienced this on multiple community servers, however I have yet to play on the NWI official servers to see if this bug is replicated there.
The stutter is also happening though. I think the term is microstutter. When looking around there's a slight, yet perceptible "cracking" in the frames or lack of smoothness. I really don't know how to describe it other than a microstutter.
