While I like the new graphics a lot, they have taken quite a toll on performance. While in The Commons, Ravenwood and Shopping District, my FPS count often goes as low as 30. Keep in mind that my PC is packed with an I5 7400 and a GTX 1050 Ti, considered to be a mid-end gaming rig that can handle AAA titles. Does this happen to anyone else?
It is most likely adjusting. I had a similar issue but its fine now. I'm sure you had the same thing happen when first getting into wizard. your computer will (if it hasn't already) get back to the running speed it was at before the update shortly most likely.
