Sorry in advance if the question is dumb, I am not a person with much or any hardware experience.
My CPU has 4gb ram, and it played wow well in wod. since legion however, graphics have gone to shit. I hearth to dal and not only does the loading screen take forever, everything in dal takes ages to load (as in to visually appear), and throughout the entire time fps is extremely unbearable. Legion has been great for me so far aside from this graphics issue. Most of my graphics options have already been reduced to near minimal settings.
My GPU is nvidia gt720. Any idea or advise on how to improve my situation would be much appreciated.
