Would it be possible to add more options for higher resolution graphics?

I’m playing the game at 3440x1440 Resolution with duo 980 TI cards (which need to be upgraded, but not going to yet) and every setting is set to Ultra and Anti Aliasing set to 6X…

Would it be possible to add an option for Anti Aliasing 8X or even up to 12X (preferred)?
Or can you tell me where the .ini file is located to set the options that way?
My graphics on my PC look like graphics on console =(

Download and run sweetFX.
AA settings do nothing but blur the game.
