Its modded to most of whats mentioned in this thread, not played it since ESO came out and just fancied to give it a go again on my new rig. Its like in some areas it doesn't matter what hardware you have got it struggles to get over 40-50fps. Even if I turn on my ENB's Ambient Occlusion in Whiterun it stays the same fps even though in other areas it would cut your fps by 30%.
My gpu mem usage is at just over 3gb and Im using 4gpb 970's.
This hasn't just started to happen, it was like this 12 months ago where I got slightly higher minimum fps with my single 780TI classy in these areas but not much. something is choking the game.
Im using Serenity ENB which was always a bit more demanding than the others but looked the best at the time. I dont know if there are much better ones now?
