I've been experiencing some lag while playing some online games lately and I'm not sure if my connection is just bad or if I have too much stuff running in the background. Does anyone know what would be a good amount of processes running, I think with my computer it's anywhere between 50-65 processes running all at once depending on what games I'm playing, is this way to much and what can I do to get the amount down? thanks for any help you can give.
