I can run dungeons and raids fine with playable fps, and my usual ping is ~40ms which is good compared to most people. For the ping lag I noticed that in Koldrak when I look at task manager the game is using up ~2.1 mbs of my network until the boss dies then goes back down, which is 100% of my bandwidth so my ping rockets to the moon. Usually the game only takes 0.1 - 0.3 mbs no matter what else I'm doing. Can't exactly tab out during Sanctum but I suspect the same thing is happening there, and I have no clue why or how to fix it because sometimes in Koldrak it stays at 0.1 - 0.3 mbs and my ping is completely fine.
As for hardware for fps lag, that other dude roasting my rig but I meet all the recommended requirements except for RAM, which meets the minimum requirements.
