@gauzy: No way, man. No mods period. Don't change a texture, and leave every one of the game's flaws intact. It's art, my friend... art. You don't paint teeth on the Mona Lisa.
eh. dark souls without DSfix was a much messier experience. i have no issue modding games for stuff like that. pcgamingwiki lists a decent looking widescreen fix, so that should do the trick.
