After the latest hotfix I am experiencing a major drop on FPS. It happened right after the latest hotfix that gone live on 12 of August. I used to have around 50-60 in many areas of the game especially in dungeons and areas where i was alone with very little movement. Now since patch I'm having max 43 and most of the times around 20-30 which is a problem because animation is breaking. Especially when I'm running veteran dungeons where is very difficult to do things due to the low frame rate.
I have the late 2013 27 inch iMac with 3,5 intel core i7, 16 Gb RAM, NVIDIA GTX 780M 3GB RAM.
I don't know if I have to report this somewhere else or some send debug files etc but I'm prepared to do everything because this is spoiling my game experience.
