Lag in dungeons, trials, raids etc. PLEASE HELP

The specs on my computer are Geforce GTX 1070, intel i5 6600, 16 GB ram.
I've been experiencing massive lag in dungeons and raids, outside of it, the game seems perfectly fine by all accounts.

The game will pretty much freeze for a second and the information on screen wont update, and then it will go back to normal, it will be fine for a few seconds and then stutter the same way once again, this has been happening to me ever since patch 5.2

If anyone can help I'd greatly appreciate it. The game is literally unplayable in this state.
