The game will need a graphic engine update to implement new graphical options like new AA methods and better textures or anything else.
As far as I know they do not plan a graphic update soon unless they secretly working on it.
More AA options and better textures are on my wishlist. And for the love of Hydaelyn the game needs a sound update as well. The most annoying technical aspect of the game is the lack of ability to switch to Headphones via front panel on PC without restating the game itself. Even games more 8 years old can do this.
