Exactly, the only real way to get Bioware to really listen is by not subscribing until its fixed and make sure you list it as the exact reason you are leaving.
I will gladly subscribe another month whenever they give us high res textures, they are already in the game it is not that hard to program in a slider or high res texture box that uses the same amount of "draw calls" as cinematics, If it makes some people get bad fps put a warning saying its only for high end systems.
Even if it meant some textures taking longer then other to draw those better textures causing texture popin(The game already does this to a point)., it would still be better then the current implementation.
