My Notebook with NVIDIA used to run the game just fine. Not on full settings but fine. I saw on patch notes that some of the changes included game performance tweaks. Well whatever they changed it made it harder for my PC.
More importantly thou is the fact that loading screens now usually take 10 - 15 minutes to complete. I'm not sure how related those things are but I wanted to throw it out there for the devs.
