SWTOR: Medium texture setting "a bug", never intended as option
Bioware's community manager Stephen Reid, as promised, as gotten to the bottom of discrepancies between the "low," "medium," and "high" texture options in Star Wars: The Old Republic. Turns out, the "medium" choice was never meant to exist in the game, meaning only "low" and "high" were actually implemented. So, the choice of "medium" was a bug. Interesting. Reid explains everything in lovely technical detail, and much better than we could, through here.
