This this and more this. I have the very same issue when playing on the ps3. I have not read one single line of dialogue from npcs during quests or anything because I can never see any of the words due to a sizing issue. However, when I took a screenshot at one point (on accident) on the ps3, the image saved on the ps3 showed the words in clarity. It sucks that I pretty much had to miss the entire dialogue of the main game because an issue that was mentioned from beta is still present and has not been fixed.
