Tried all the fixes and whatnot, so I'm just stuck here waiting for them to hopefully fix it, and by the looks of various forums I'm not alone. Thankfully Steam refunds now exist, so I'll be getting one of those if this isn't addressed soon.
Disappointing, but not unexpected. I'm not one to purchase games at release, precisely because of things like this, but Fallout is one of the few exceptions I'm willing to make.
Granted, the game is not looking great, especially for someone whose idea of a perfect Fallout game is New Vegas. From what I've read and seen, a lot of it is dumbed down compared to the previous games, with things like the new dialogue wheel looking especially terrible, along with a smörgåsbord of other issues to give modders a ton of work to do. The story and writing are also apparently typical Bethesda, which is to say they're trash.
Hopefully once I can actually play it I'll be pleasantly surprised, but I've played enough Bethesda games to not set my expectations too high. Oh well, we'll see.
