I tried uninstalling both. Put NW on my SSD along with Teamspeak, still lags. Only progress I have got is if I change the priority of teamspeak to Realtime through task manager. It still lags when I do that but it isn't as bad. I bought a new PC a while back and its high tier so I know it isn't because of weak equipment.
Discord works fine so it's something with teamspeak.
