Go to device manager, check your properties of your network card, go to driver date. Now find the latest driver online for your network card or onboard network device, update that #@@!. Your problem if it was truly stuttering multiplayer game without real lag or fps drops, you should have it fixed.
Let me know if this works .. also double check to make sure you updated your driver correctly.
So I have been trying to troubleshoot and search for a fix to the stuttering I experience every 3-5 seconds, I get 140 fps maxed graphics, tried all different settings, downloaded all drivers, tried rollbacked drivers, reinstalled windows (7). My net connection is DSL. I dont stutter lag in any other game, Please, people need a fix for this.
Watch this video: The guy has a solid frame rate but gets stuttering for no reason. This is what a ton of people are getting.
Edit #2: I stutter worse or as bad as that video, it varies depending on unknown variables.

The stutter is usually an issue with limited internet connectivity. Other online games from MMOs to FPS all run smoothly with decent ping. I even have leatrix configged. Um so yeah thanks blizzard for ruining my life
