I've read both parts of the change log. I guess we'll see if the Steam overlay is fixed on April 17th. If not, I guess I'll be uninstalling and never looking back. And never buying a CDPR game again. I know this probably sound elitist and cry babyish. But I bought the game on Steam for a reason, and that reason does not work now. So why play if I can't take advantage of those features? Could a dev chime in and confirm whether or not the overlay is fixed, or if it will ever get fixed?
EDIT: You can install a friend's GOG copy if you're that bothered.
