But they released the game for PS3. Should have though about that before designing the engine. And well, they did make Skyrim work. Even tho they did it after a month or two, basically my 60$ game was unplayable, which is incompetence. And also, that is a theory thrown around by a Obsidian developer. We dont really know the cause.
