I didn't see any change in anything graphically. I did wonder if since you have to download all the areas again whether maybe they optimized the code for the spaces to load faster or something but I couldn't really see a difference there either.
nope sorry, I dont see any difference either. They lower the detail of characters when you're not close to them and increase the detail as they get closer, maybe this is what you're noticing? It dosent always shift immediatly and people can look horrible until the load is complete.
