Why in the nine hells, have they not implemented a borderless window option in skyrim yet?
It makes absolutely no sense that they to this day, have not fixed this issue, and im guessing fixing it for skyrim would mean fixing it for fallout as well, as its pretty much the exact same engine.
But its a bloody disgrace, that they are using the awesome mod community to provide a function that any decent game in this day and age should have as default.
