Stuttering on Blackrock Realm

Hi guys, i recently discovered the obnoxious screen stuttering ive been getting whilist playing on the Blackrock realm, it doesn't happen at any other realm, literally just on Blackrock, it doesn't even stutter on the original game (Warlords of Draenor), neither does it stutter on other private servers.

So my question is; is there any way to fix this? Because i actually enjoy playing and it would be alot more fun if i could actually play smoothly, my specs are good, and i have good fps in-game, probably around 120+ in BG's its just that it stutters so it makes it uncomfortable to play.

what do you mean? freeze? fps drop randomly?
try to disable all of your addon

Well i do fps drop too, sometimes when im just running around in Stormwind or waiting for the queues, my fps drops like 20 or 30 frames, but it stutters very often when i play battlegrounds, freezes for like half a second then it gets back to normal, then it keeps on doing that forever.

Fixed; removed all addons i had and the game is running smoothly agian.

Im having error 132 from time to time aswell.. maybe if i remove all addons it will be fixed aswell but.. cant play without my addons heh :P
